product was then distilled using a Hickman still and characterized using infrared spectroscopy. The percent yield of isopentyl acetate was 61.52%. This may have been low due to not all of the condensed product being removed from the Hickman still‚ some product being lost during transfer of the product from the reaction tube into the Hickman still‚ or the loss of some product due to evaporation during distillation. Infrared spectrum analysis of the product indicated that the product was isopentyl

whether or not fermentation had occurred in the Phenol Red Broth. The first part of this test was for glucose fermentation with my results being +‚ which represented acid fermentation based on the yellow broth‚ and G‚ which represented gas end-products in the tube. The second part of the test was for lactose fermentation with my results coming back -‚ indicating that no fermentation occurred as a result of the red broth. The final part of the Phenol Red Broth tested for sucrose fermentation and my

Aspirin Synthesis Introduction Out of all the pharmaceutical drugs in the worlds‚ aspirin is made the most. Any potential pharmacist must be familiar with synthesizing the drug. The goal of this lab is to synthesize as much pure aspirin as possible. The reactants‚ acetyl anhydride and salicylic acid‚ must react in phosphoric acid. With phosphoric acid as a catalyst‚ the reaction yields aspirin and acetic acid. The equation for the reaction is as follows: “(CH3CO)2O + HOC6H4COOH □(→┴yields ) CH3CO2C6H4CO2H
