The combination of 3% CrO3 in glacial acetic acid finds numerous applications in organic synthesis. Notably, it is employed in the selective oxidation of alcohols, where chemists can carefully manipulate reaction conditions to achieve high selectivity and efficiency. Additionally, this system has been utilized in the oxidative cleavage of carbon-carbon double bonds, which is crucial for synthesizing a wide range of organic compounds. The mild yet effective nature of this oxidizing system has made it a valuable tool in both academic research and industrial applications.

The production of glacial acetic acid is predominantly through the carbonylation of methanol, a process catalyzed by metal salts. This method has largely replaced earlier methods that involved the oxidation of acetaldehyde or the hydrolysis of acetyl chloride. The main reaction involves the conversion of methanol and carbon monoxide into acetic acid, yielding a highly concentrated solution. The efficiency of this process has enabled the mass production of glacial acetic acid, making it readily available for various industrial applications.

In addition to its role in the chemical industry, glacial acetic acid is widely employed in the food sector as a food preservative and flavoring agent. It is the primary component of vinegar, which is used in various culinary applications, ranging from pickling vegetables to dressing salads. In this context, glacial acetic acid can be diluted to produce the desired concentration for safe consumption and preservation.
