Despite its widespread use, handling glacial acetic acid requires caution due to its corrosive nature. It can cause burns on contact with skin or mucous membranes and should always be used in a well-ventilated area with appropriate personal protective equipment. Proper storage and disposal methods are essential to minimize any environmental impact and ensure safety.

Glacial acetic acid is a colorless, hygroscopic liquid with a pungent odor and a high boiling point of 118 °C. It is a key raw material in the production of numerous chemicals, including acetic anhydride, acetate esters, and even some pharmaceuticals. One of its important features is that it can serve as both a solvent and a reagent due to its polar nature, which allows it to dissolve a wide range of polar and non-polar compounds.

Acetanilide, also known as N-phenylacetamide, is synthesized through the acetylation of aniline. Aniline, a primary amine, reacts with acetic anhydride or acetyl chloride to form acetanilide. Both acetic anhydride and acetyl chloride are potent acetylation agents; however, these reactions often require a controlled environment to manage excess reagents and ensure high yield. This is where glacial acetic acid comes into play as an efficient solvent and reagent.

To mitigate these hazards, proper training and awareness programs for all personnel involved in the handling of glacial acetic acid are necessary. Employees should be educated about the risks, safe handling procedures, and emergency response actions in case of an accident. Regular safety audits and assessments can also help identify potential risk areas and enforce adherence to safety protocols.
