Experiment Four: Organic Synthesis of Aspirin Abstract The purpose of this experiment is to synthesize a common organic product called acetylsalicylic acid (aspirin)‚ and to become familiar with the optimum conditions needed for successful yields. Aspirin is produced from an acid catalyzed reaction between salicylic acid with acetic anhydride. The crystalline aspirin is synthesized and purified by recrystallization‚ although there is not a hundred percent yield due to sources of error. Introduction

In this lab‚ we will be finding the limiting reactant between Copper(II) Chloride and Aluminum. The limiting reactant is‚ reactant is‚ the reactant in a chemical reactant that limit’s the amount of the product that can be formed. We will also need to find the molarity of Copper (II) Chloride in the solution. The molarity

The Synthesis of Organic Aspirin ABSTRACT: The purpose of this experiment was to find out how a reaction undergoes for a globally known painkiller called aspirin‚ and to become familiar with achieving successful yields. Aspirin is synthesized from salicylic acid and acetic anhydride. Those two chemicals are mixed together along with sulfuric acid to form a crude solid. Filtration is used separate the impurities from the crude aspirin. To get purified aspirin‚ the precipitate was heated until all
