Essays on Acetic Anhydride

Abstract

This lab experiment involved P-Methyl-Acetanilide synthesis from acetic anhydride and a solution of sodium acetate. Different techniques were used in this lab exercise including; vacuum filtration, crystallization, and spectral analysis. The main aim of performing this experiment was to synthesise, isolate, evaluate and analyse P-Methyl-Acetanilide product. We synthesised the product and then, isolated the product by the process of the vacuum filtration. We evaluated the products purity by melting point analysis and performed a spectral analysis (1HNMR spectroscopy) later. The 1HNMR spectroscopy interpretation is a method/ technique used to determine the structures of organic compounds that are unknown (Pavia 128). It stands ...

Chemistry can be described as the branch of science concerned with the substances of which matter is composed, the investigation of their properties and reactions, and the use of such reactions to form new substances.

The Mechanisms and Synthesis of Aspirin

Aspirin is also known as acetylsalicylic acid (ASA). It is a salicylate drug used as an analgesic (something that relieves pain without producing anesthesia or loss of consciousness) for minor aches and pains, as an anti-inflammatory drug, and as an antipyretic to suppress fever. (Vane & Bottling 2000) The name “Salicylic acid’ was derived from salix, which is the willow family of plants. In ancient ...

Introduction

Aspirin is a commonly used drug. One of the properties of aspirin is that it is an analgesic, meaning that it relieves of pain. Aspirin is also an antipyretic drug meaning that it relieves on of fever. It also has anti-inflammatory properties meaning that if readily relieves swelling from tissues (Ahluwalia, Sunita & Adarsh 231). Salicylic acid has two functional groups. One of the functional groups is the phenolic group while the other functional group is carboxylic acid group. The presence of these two functional groups means that salicylic acid can undergo esterification in two different reactions. In one reaction, ...

Lab report on Preparation of Aspirin

Lab report on Preparation of Aspirin Introduction The chemical name for aspirin is the acetylsalicylic acid and is a drug that is used as an antipyretic. Aspirin reduces fever, relieves the pain and inflammation (Thomson Healthcare, 2012). The compound structure of acetylsalicylic acid has an ester group and is produced through an esterification reaction. Aspirin is synthesized through a reaction of salicylic acid with acetic acid using sulfuric acid as a catalyst. The reaction equation occurs as shown below. The experiment aimed at synthesizing aspirin, providing an opportunity to familiarize with vacuum filtration as well as melting point techniques. ...
