composed of sucrose (10%)‚ aspirin (40%)‚ and Tylenol (50%). Although this information is reported‚ the true composition of Panacetin is questionable. While sucrose and aspirin are present in Panacetin‚ Tylenol may be replaced by an unknown component (acetanilide or phenacetin). Separation of the components of a sample of Panacetin may prove valuable in identification of the unknown component‚ as well as the true percent composition of each component of Panacetin. This experiment involves two parts‚ covering

Objective: Separate and purify acetanilide from a mixture by recrystallization. Compare the melting points of crude and recrystallized acetanilide. Introduction : The most common method of purifying solid organic compounds is by recrystallization. In this technique‚ an impure solid compound is dissolved in a solvent and then allowed to slowly crystallize out as the solution cools. As the compound crystallizes from the solution‚ the molecules of the other compounds dissolved

The early twentieth century led to the discovery of penicillin‚ which revolutionized the use of curative agents to combat many bacterial contagions found around the globe. This was particularly useful in 1943 when the War Production Board outlined a plan to mass-produce a powdered formula of the drug to aid in the WWII American war effort.1 Penicillin’s use on Allied forces in the field reduced the number of amputations and deaths by an estimated 12-15%.2 Despite penicillin’s continued use today

CHEM 2123 and 2125 – Organic Chemistry Lab I and II GUIDELINES FOR WRITING LAB REPORTS INTRODUCTION Writing reports in organic chemistry lab may differ from the way it’s done in general chemistry. One goal of this course is to introduce you to the record keeping methods used in research labs. Such methods are designed to organize experimental data in a format similar to that required for publication in major scientific journals. Here are some important considerations that apply in research settings

asses the pharmaceutical preparation of Panacetin‚ by using it ’s solubility along with other organic molecules. We know that Panacetin is made up of sucrose‚ aspirin and some other unknown substance. We know the substance has to be Phenacetin or Acetanilide. To help solidify our reasoning‚ we need a % recovery of 8-12% sucrose‚ 35-45% aspirin and 45-55% unknown. Sucrose for example is insoluble in dichloromethane‚ while aspirin is soluble in CH2Cl2‚ but not in H2O. The organic compound sodium hydroxide
