Another critical aspect of utilizing glacial acetic acid in plasmid isolation is its contribution to the stability of plasmid DNA. Maintaining the integrity of plasmid DNA is paramount for its functionality in later experiments. The presence of glacial acetic acid helps to stabilize the DNA during the purification process by minimizing degradation caused by nucleases that could be present in cellular debris. By creating an acidic environment, glacial acetic acid inhibits the activity of these enzymes, thus protecting the plasmid DNA during isolation.

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

Glacial acetic acid, known chemically as ethanoic acid, is a colorless liquid with a distinctive sharp odor. It is a vital organic compound and a key component in numerous industrial processes. One of its notable physical properties is its density, which is approximately 1.05 g/mL at room temperature. Understanding the density and other characteristics of glacial acetic acid is crucial for its various applications in industries ranging from food production to chemical manufacturing.
