I graduated college and my father fell ill. I felt I must start working somewhere to bring in a source of income since the breadwinner as out of commission. ON the plus side I also learned how to paint automotive cars and have a degree in Egineering. I was then hired on by Amazon as area manager and excelled in associate relations, daily reports, communication, coaching, and engagement. I learned much about operations and received several verification and completed an on boarding academy. Yet, my desire lies in the engineering, research, laboratory fields. I want to get back to my roots.

Characterization of Photo-processes of HEPRC Dye

https://documentcloud.adobe.com/link/review?uri=urn:aaid:scds:US:f6a1c88f-30ca-4867-ad22-a5f5aaa9d274 May 2017

Leuco dyes are characterized by their ability to switch between chemical forms, resulting

in a change of color as a response to pH, temperature or radiation. The dye Hexahydoxyethyl Pararosanaline Cyanide (HEPRC) was examined for its unique light-sensitive properties. At higher temperatures, it displays photochemistry by turning from colorless to blue, and, at lower temperatures, it displays photophysics by fluorescing. Using a 337 nm laser as the source of excitation, the emission spectra of HEPRC changed over a range of temperatures indicating this change in photo-based behavior. The appearance of the peak at 650 nm in the emission spectra taken indicates the change from photochemistry to photophysics occurs around -100 ºC.

Analysis of the Effects of Separating Ethanol from Water Using a Distillation Column

https://drive.google.com/file/d/1-1NEakv1S2mkx0g_mabQtQ2Xx9--b2mO/view?usp=sharing April 2017

The objectives of the experiment were to analyze efficiency and contacting behaviors throughout the column under varying boil-up rates, and to identify the differences in column efficiency between the Fenske equation and the McCabe-Thiele method. In a different experiment, a computer program (HYSYS) was used to simulate the continuous operation of a distillation column to meet specific target purities, with the objective of comparing the theoretical values against experimental data.

Synthesis of Umbelliferone via Pechmann Condensation

https://documentcloud.adobe.com/link/track?uri=urn:aaid:scds:US:ba5ad98c-608b-47a8-be4b-a1e34cd784e4 February 2017

Umbelliferone is a compound from plants that contains the structure of coumarin, which

is known for its herbal medicinal uses, making umbelliferone useful for its biological assets. Coumarins are formed of natural products and are common in pharmacology compounds.1 They are synthesized from different pathways including Pechmann, Perkin, Knoevenagel, etc., making them a useful factor.1 For example, zinc oxide has been used as a heterogeneous catalyst because of its non-toxic, inexpensive, and environmental benefits and has also been used in cancer treatments.1 The zinc oxide nanoparticle acts as a catalyst by synthesis of coumarins in Knoevenagel condensation.1 Coumarins are in the spotlight for researchers in the medicinal

fields due to their biological properties. They are also intensely fluorogenic compounds naturally, increasing the importance of the organic structure. Umbelliferone has fluorescence properties that effect the function of pH and excited wavelength.2 It’s commonly used for its fluorescent substrate functions including analyzing enzymatic activity at different pH levels to determine enzymes.2 The synthetic experiment produces umbelliferone through the Pechmann condensation whereas the Knoevenagel condensation was used in the example above

Dissociation of a Propionic Acid Vapor

https://documentcloud.adobe.com/link/track?uri=urn:aaid:scds:US:c5fe239c-61dc-4b3c-a57a-5edb4d2327c7 September 2017

The dissociation of propionic acid in the vapor phase was examined in order to determine thermodynamic data such as Gibbs free energy enthalpy, entropy, and the equilibrium constant for the acid dimer. This data was ascertained as a function of temperature. A glass tubed system initially under vacuum conditions was used to transport propionic acid vapor to a bulb residing inside a closed off oven. The initial mass of the propionic acid was measured and the tubing was primed. The propionic acid’s vapor pressure due to monomer dissociation was recorded over 3ºC temperature intervals. The standard enthalpy ΔH0 was calculated to be 77.7 1 kJ/mol, ΔS0 was derived as 0.187 0.008 kJ/mol K, and ΔG0 was calculated as 21.96 2 kJ/mol. Two hydrogen bonds break during per dissociation of one dimer, thus the strength of the hydrogen bond was found to be half that of ΔH0 equal to 44.9 0.9 kJ/mol.

Distillation column efficiency for batch versus continuous distillation of ethanol/water

https://documentcloud.adobe.com/link/track?uri=urn:aaid:scds:US:83a0b7bf-ceb8-4b46-9382-685579198103 April 2017

The objective of our experiment was to observe distillation column operation with varying boil up rate and to determine the efficiency of this operation. Also, we observed the column and continuous operation, and compared the temperature profiles and efficiencies of the theoretical values.

In conclusion, this experiment showed that increasing pressure drop over the column caused an increase in boil up rate. This initially increased efficiency of the column until foaming began to occur at too high of a rate, which caused more water to go into the distillate, and thus decreased efficiency. When comparing the actual tray temperatures with the HYSYS data for continuous distillation, we found that the temperatures of our experiment were relatively close to the values predicted by HYSYS. Also, the compositions that were desired by using the PI control showed to be also very close to the target compositions. Ultimately, this shows that our experiment was carried out successfully relative to the theoretical and target temperatures and compositions.

Determination of the Second Virial Coefficient for Carbon Dioxide

https://documentcloud.adobe.com/link/review?uri=urn:aaid:scds:US:764b2678-0b2f-4a96-843e-ce7f5d5df71a September 2017

The ability to accurately calculate the virial coefficient, given the other necessary variables, as discussed previously, is very common in laboratory setting and said values are used widely in industry. These coefficients, that numerically address the issue in environments outside the scope of the ideal gas law, are used to optimize processes such as those containing chemical reactions. For example, given reading of temperature and pressure the molar volume or number or moles needed or remaining can be determined with less error resulting in less waste and more efficient deployment of reactant ratios to maximize output. Majority of industrial processes such as ammonia synthesis are conducted outside the range of the ideal gas law and virial coefficients for its equation of state help to eliminate uncertainties under these conditions and facilitate accurate numerical analysis.

Separation of Porcine Pepsin and Mucor Rennet using HPLC

https://documentcloud.adobe.com/link/review?uri=urn:aaid:scds:US:0eeb7f0a-fed4-4f22-ae9b-0eff29b78d87

The objective for this experiment was to design a fast and efficient method to separate porcine pepsin and mucor rennet in a buffer solution using high-performance liquid chromatography (HPLC). To accomplish this, the salt concentrations required to elute each protein were determined and a method was designed based on the retention time and the determined salt concentrations. The results for the fast and efficient method were then compared with the gradient elution method to evaluate the effectiveness of the separation method.

Synthesis of 4-chloro-N-(2-morpholinethyl)benzamide (Moclobemide)

https://documentcloud.adobe.com/link/track?uri=urn:aaid:scds:US:d8c3ffb4-d785-4e49-abc6-e910f75fe15d

The purpose of this experiment was to synthesize 4-chloro-N-(2-morpholinethyl)benzamide (3) using nucleophilic acyl substitution from 4-chlorobenzoyl chloride (1) and 2-morpholinoethan-1amine (2) in a cold water bath. Upon completion, extraction via vacuum filtration isolated the crude product hydrochloride salt. Recrystallization was used to purify the moclobemide salt, which was then converted into its neutral form by extraction using a biphasic basic mixture. The purified opaque white solid moclobemide was to be analyzed by 1HNMR, 13CNMR, IR, and melting point to determine the success of the synthesis and determine any impurities.7 However, during the final purification to the neutral salt using concentrated ammonium hydroxide, the isolated neutral moclobemide was an opaque white solid as desired, with a yield of 47% and mass of 477 mg.

ADDITIONAL INFORMATION

Team E: David Shagin, Bradley Nixon, L. Erik Woistman, Kevin Yanchitis

The objective of this experiment was to determine the overall mass transfer coefficient for the extraction of propionic acid (PA) from an organic phase of N-propyl bromide (NPB) to an aqueous phase (water) using a continuous countercurrent liquid-liquid extraction (LLE) column. The process was repeated at various flow rates to determine the impact of flow rate on the mass transfer coefficient, the fractional extraction, and the column efficiency.

A block diagram of the countercurrent LLE column is shown in Figure 1. 112 mL of propionic acid was added to the 10L NPB feed reservoir to achieve a concentration of approximately 0.15 M. The calibrated feed pump for NPB was calibrated and verified using a stopwatch and a graduated cylinder and was set to flows of 0.15, 0.20, 0.25, and 0.30 L/min throughout the experiment. The water pump was set to the same flow rate as the NPB feed pump for each of the flow rates. Tap water was used to fill the water solvent feed reservoir. For each feed rate, approximately 50 mL of the water extract was collected at 6-8 times ranging from 0-4τ, where τ is the residence time of the water solvent. Each of these samples was titrated with 0.1M NaOH and phenolphthalein to determine the concentration of propionic acid in the water. At the end of each run, a sample of NPB raffinate was also titrated to determine the propionic acid concentration. The equilibrium distribution

coefficient, Kd, was verified by dissolving 1g of propionic acid in a 50/50 mixture of NPB and water and titrating the aqueous phase after mixing.

The expected feed concentration was 0.15 M based on the amount of propionic acid and the 10L of NPB present in the feed reservoir. The actual concentrations were 0.14, 0.15, 0.19, and 0.16 M for the respective flow rates of 0.15, 0.20, 0.25, and 0.30 L/min. One possible cause for this is that the amount of NPB was not an exact amount as it was measured using only a level indicator on the sight glass. Another possible cause was that the feed reservoir was mixed for several minutes and then allowed to settle. After the mixing stopped, it is possible that propionic acid was no longer perfectly mixed. As the pump took out NPB, the amount of propionic acid could vary depending on where the pump was drawing from.

Figure 2 shows the relationship between the fractional extraction vs. the reduced time for each of the different flow rates. After being normalized by the residence time, each of the different flow rates reaches steady state at approximately 2 residence times. Before that, the fractional extraction is linear with respect to reduced time. This information is useful because it helps you predict how long you need to run the column before reaching steady state. After approximately two residence times, the fractional extraction and extract concentrations remain fairly constant.

The steady state fractional conversion remained relatively constant at different flow rates (85.6% to 88.2%). The flow rate only affected the rate at which the steady state fractional conversion was reached, as faster flow rates had shorter residence times. This indicates that the degree of extraction/mass transfer achieved by this set up is caused by the column packing and tower height, not the flow rate of fluids.

The flow down the packing in the column is expected to be laminar. An estimation for the Reynolds number for the packed column for each flow rate is shown in Table 1. The Reynold’s number was calculated using equation 1:

1.

where v=mean velocity of liquid (m/s), D=diameter of glass tube (0.01 m), and μ=kinematic viscosity (m2/s). Although the Reynold’s number increases slightly with flow rate, all values are still very far below the threshold of 4,000 required for turbulent flow. Based on the expectation of laminar flow, higher NPB pump rates should have no impact on the size of the NPB droplets in the column.

The apparent mass transfer coefficient increases with increasing water flow rate as shown in Figure 3. This is consistent with the theoretical equation for the coefficient as shown below.

The terms in the equation that will have the greatest effect on the observed coefficient and interfacial area are the water flow rate. This is because the log mean driving force does not vary with flow rate, as the concentration gradient through the column is constant. The area and z are known values from the physical design of the column and are also constant. This observation is consistent with the fact that shorter residence times (faster NPB flow rate) require a large mass transfer coefficient. This is because more mass transfer has to be achieved in a shorter time period to maintain the constant steady state fractional extraction.

The operating lines for each flow rate are about the same and share the same distance from the calculated equilibrium line. This indicates that the difficulty of extraction does not vary with flow rate.

The NTU and HTU values for each flow rate vary slightly. However, for each flow rate, the product of their respective NTU and HTU values yield the same required packing height of 120 cm. NTU is a theoretical measure of separation difficulty, similar to theoretical trays in a distillation column. Higher NTU values indicate a more difficult separation but also a more efficient separation as the streams gets closer to equilibrium. Therefore, a higher NTU for a particular flow rate will yield a lower HTU value because the packing height doesn’t change and the fractional conversion for each flow rate is constant. In conclusion, the overall fractional extraction of propionic acid from an organic phase to an aqueous phase in a packed bed column was constant with varying solvent flow rates. The overall mass transfer coefficient was found to increase with increasing flow rates in order to compensate for decreased residence time in the column. The amount of separation in the column is mostly influenced by its height and degree of mixing achieved by its packing.
