A. Abstract Aspirin is the common name for the compound acetylsalicylic acid, widely used as a fever reducer and as a pain killer. The first part of the experiment aims to synthesize aspirin from the reaction of salicylic acid with acetic anhydride with the aid of phosphoric acid as a catalyst. The second part of …
Introduction: The Diels-Alder reaction is a [4+2] cycloaddition of a conjugated diene and a dienophile. This type of reaction was named for Otto Diels and Kurt Alder who were the first to investigate this reaction (Weldegirma, 2012). The Diels- Alder reaction is one of the most important reactions in all of organic chemistry because of …
Abstract: The purpose of this lab is to synthesise acetylsalicylic acid (aspirin) by creating a reaction between acetic anhydride and salicylic acid. This was be accomplished through the use of recrystallization. Acetic anhydride and salicylic acid are mixed together, and then acidified by the addition of a few drops of concentrated sulfuric acid, which catalyzed …

But when you start playing around with constitutions, just to prohibit somebody who cares about another person, it just seems to me that’s not what America’s about.” Barack Obama The marriage has traditionally defined between man and …
VI. RESULTS AND DISCUSSION Aspirin is prepared by the esterification of salicylic acid with acetic anhydride under acidic conditions. The phenol group in salicylic acid is replaced by a carboxyl group through electrophilic substitution. The mechanism for the reaction can be summarized as follows:
