Synthesis of acetic acid by oxidation

LC2.4.1.1
Synthesis of acetic acid by oxidation
Synthesis of acetic acid by oxidation

Description

Acetic acid is an important basic chemical in the chemical industry and is also found in everyday life in cooking vinegar, as vinegar essence and in cleaning agents. In this experiment, the students will produce acetic acid by oxidising ethanol with potassium permanganate. In the process, the discolouration of the solution gives an indication of the reaction mechanism and enables the students to develop a general synthesis strategy for carboxylic acids.
