as crude oil and sour and residual oil (2). The complex refining and distillation processes for Valero can be compared to the experiments performed in an Organic chemistry lab. From what the company’s procedures are to what the Lab

Organic Lab 1: Fractional Distillation Discussion: With the purpose of the experiment being to identify the 30 mL of unknown liquid, the theoretical basis of simple and fractional distillation must be deconstructed and applied to the data obtained describing the liquid in question. Simple distillation is a separation technique which can be used to separate and purify distillates from a liquid mixture which ideally contains one volatile and one non-volatile compound. If such ideal conditions are

Fractional Distillation and Gas Chromatography Lab Report Introduction: Distillation is a method of separating two volatile chemicals on the basis of their differing boiling points. During this lab, students were given 30 mL of an unknown solution containing two colorless chemicals. Because the chemicals may have had a relatively close boiling point, we had to employ a fractional distillation over a simple distillation. By adding a fractionating column between the boiling flask and the condenser

LAB REPORT I: FRACTIONAL DISTILLATION AND GAS CHROMATOGRAPHY INTRODUCTION The purpose of this lab is to investigate the processes that can be used to separate two volatile liquids in a mixture based on their chemical properties. This is accomplished by fractional distillation, which separates chemicals in a mixture by differentiating them by their boiling points at atmospheric pressure. Specifically in this lab, fractional distillation is used to separate an unknown mixture into its respective pure

form of the drug, is marketed and sold by the pharmaceutical companies Pfizer and Eisai. However, the company Sandoz now makes a generic brand form of the drug as well, known as Sandoz’s Donepezil. Another generic form of donepezil created by Ranaxby Labs gained USDA approval in November of 2010, and a third generic form, made by Wockhardt, is in the process of gaining approval for sale (RxList). Figure 1: Chemical structure of donepezil (TRC). 3 Major Alternative Products to Donepezil Apart from donepezil
