Despite their widespread use, it is crucial to handle glacial acetic acid and ethanol with care. Glacial acetic acid is corrosive and can cause severe burns, while ethanol, in large quantities, is flammable and poses potential health risks when ingested or inhaled. Proper safety protocols, including using personal protective equipment and working in well-ventilated areas, are essential when working with these substances.

While glacial acetic acid is an important industrial and laboratory chemical, it poses significant safety risks. Exposure can cause severe skin and eye irritation, burns, and respiratory distress. Therefore, it is crucial to handle this chemical with great care. Appropriate personal protective equipment (PPE), such as gloves, goggles, and lab coats, should always be worn when working with concentrated acetic acid.

Following the formation of acetic acid, the product mixture often contains water, unreacted methanol, and other by-products. Therefore, it is necessary to separate the acetic acid from these contaminants. This separation can typically be achieved through distillation, resulting in a high purity of glacial acetic acid. The distillation process utilizes the difference in boiling points to isolate acetic acid from water and methanol.
