Date: May 22‚ 2012 Name: Cristhian Valor Organic Laboratory Pre-Lab 1. Main reaction sequence including side reaction products: 2. 3 Sentence Summary of the Experiment: The OH group on the benzene ring in salicyclic acid reacts with acetic anhydride to form an ester functional group. Thus the formation of acetylsalicyclic acid (aspirin) is referred to as an esterification reaction‚ which requires the presence of H+ (H2SO4 in our case). The technique used to purify the aspirin content

Organic Chemistry II Laboratory (ABCT357) Although studying fundamental theories of chemistry in the class is important to understand the concept of chemistry‚ carrying out experiments to corroborate the theories is also important. It is very important for students to get used to experiments in order to speed up their experiments. Expt.1.

Many people will die every day if we do not research on animals. Animal research is important because scientists will learn how to operate‚ also animals are considered like models for human diseases‚ and scientists use animals to create
