This experiment allowed the students to conduct the synthesis of aspirin‚ acquire the skills of recrystallisation using normal filtration and reinforce the technique of the melting point determination. The method used to synthesize aspirin was esterification by reacting salicylic acid with acetic anhydride with the presence of dehydrating agent‚ conc. sulphuric acid‚ to speed up the reaction. Having obtained the crude aspirin which was still impure‚ recrystallisation was conducted to remove the impurities

Date of Experiment: September 10th‚ 2013 Organic Chemistry II – CHLB330 Name: Symone E. MoxeyLab Partner: Lynden Cooper Synthesis of Aspirin (Acetylsalicylic Acid) Abstract:- Aspirin (acetylsalicylic acid) is produced experimentally in the lab. The resulting percentage yield is 65.5%. The purity of the obtained product is tested using the melting point and Ferric Chloride Test (FCT). The aspirin was massed‚ and the melting point was determined. Based on the data collected‚ there was a total

INTRODUCTION: Carboxylic acids are organic acids characterized by the presence of a carboxyl group‚ -COOH. This acid acts as a weak acid‚ which can react with a strong base. Carboxylic acids form hydrogen bonds with many water molecules and are more soluble with one to four carbon atoms. Also‚ it may have an R group that consist of hydrogen or an alkyl group that changes its water solubility. Carboxylic acids with low molecular weight have odor at room temperature and higher molecular weight

The Guardian is a 2006 action-adventure drama film directed by Andrew David. The lead characters are Ben Randal and Jake Fischer. The setting for the movie is the United States coast guard and their Aviation Survival Technician (AST) program. The movie’s title introduces a mythical tale: people lost at sea often claim they feel something lifting them to the surface‚ breathing life into their bodies while they are waiting for help to come. They call this something “The Guardian.” Ben Randall (Kevin

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 is called crystallization‚ which consists in allowing the reaction to cool‚ decreasing the solubility of acetylsalicyclic acid and
