1. Carbonylation of Methanol This is the most commonly used method in the industry today. It involves a chemical reaction where methanol (CH₃OH) is reacted with carbon monoxide (CO) in the presence of a catalyst, usually rhodium or iridium. The process is carried out under high temperature and pressure conditions, resulting in the formation of acetic acid. The reaction is as follows

In laboratories, glacial acetic acid serves as a solvent or reagent in chemical reactions. Its hygroscopic nature allows it to absorb moisture from the environment, making it valuable in dehydrating agents and electrolyte solutions. Furthermore, it is frequently employed in titrations and can facilitate reactions requiring a strong acid. Scientists also utilize glacial acetic acid in the esterification process to synthesize various esters that are vital in flavoring and fragrance industries.

It is important to note that glacial acetic acid is a hazardous chemical and should be handled with care. Before purchasing, be sure to familiarize yourself with the proper safety guidelines for storing, handling, and disposing of the chemical. Always wear appropriate personal protective equipment, such as gloves and goggles, when working with glacial acetic acid.
