1. Methanol Carbonylation This is the most widely used method for producing industrial-grade acetic acid. In this process, methanol (CH3OH) reacts with carbon monoxide (CO) in the presence of a catalyst (usually rhodium or iridium). The reaction proceeds under high pressure and temperature, resulting in the formation of acetic acid. The overall reaction can be summarized as follows

In recent years, there has been increasing interest in the sustainable production of glacial acetic acid. Traditional methods often involve fossil fuels, leading to environmental concerns. As industries shift towards greener practices, the exploration of bio-based production methods using renewable resources, such as biomass, has gained traction. This transition not only addresses sustainability issues but also aligns with global initiatives aimed at reducing carbon footprints.

Before delving into storage practices, it's important to understand what glacial acetic acid is. This chemical is characterized by its high purity, containing over 99% acetic acid by weight. It has a freezing point of about 16.6 °C (62 °F), at which it solidifies into a crystalline form. As a strong acid, glacial acetic acid can cause severe burns upon contact with skin and can lead to serious injuries if inhaled or ingested.

Glacial Acetic Acid Safety Data Sheet Overview from Sigma Aldrich

Despite its beneficial uses, handling anhydrous acetic acid requires caution due to its corrosive nature. Exposure to concentrated acetic acid can cause severe skin burns and damage to mucous membranes. Therefore, proper safety measures, such as the use of personal protective equipment and effective ventilation, are essential in workplaces that utilize this chemical.
