acidification of salicylic acid and acetic anhydride. The objective was to convert a specific amount of salicylic acid into the same amount of aspirin that was high in purity. Furthermore‚ the other objectives were to enable students to conduct the synthesis of aspirin‚ reinforce skills or recrystallisation and the technique of melting point determination. The amount of each compound should be the same because there is a 1:1 ratio between them. The purity of the synthesized aspirin was measured by determining

Synthesis of Aspirin Learning Goals 1. To synthesize aspirin from salicylic acid and acetic anhydride. 2. To purify the crude product by Recrystallization. Introduction Most drugs are chemical compounds which are described as "organic compounds" because they are comprised primarily of the elements carbon‚ hydrogen and oxygen. The present experiment will be the synthesis of a familiar organic compound called aspirin. The common chemical name is acetylsalicylic acid. Aspirin‚ the

expression cannot be expected for different individuals with a shared gender. Occasionally‚ a person’s gender expression may not even match their gender identity. In actuality‚ each person’s gender expression varies in different situations. For example‚ someone wakes up in a grumpy mood‚ wearing sweatpants‚ and simply not caring what they look like – at this time‚ they are experiencing a slightly masculine expression; the person walks down the hall‚ pours some cereal‚ and goes to pour the milk but

Lab 3: Grignard Synthesis Objective: The goal of this lab is to synthesize a Grignard reagent from bromobenzene and magnesium metal in diethyl ether. This same Grignard reagent would then be used to prepare a tertiary alcohol and then purify and characterize the product.
