To dilute glacial acetic acid safely, one should always add acid to water, never the other way around. This method is known as the acid to water principle and is a critical safety guideline. When water is added to acid, it can cause a highly exothermic reaction that may lead to splattering or even boiling of the liquid. By adding acid to water, the heat generated is dissipated throughout the larger volume of water, significantly reducing the risk of splashes and accidents.

In addition to esterification, glacial acetic acid and ethanol may also be involved in other chemical reactions within industrial processes. For example, both compounds can serve as precursors in the synthesis of various pharmaceuticals, agrochemicals, and other important organic molecules.

In cases of accidental exposure, it is vital to follow first aid protocols, which may include flushing the affected area with water and seeking medical attention for severe reactions. Additionally, proper storage practices should be followed, keeping the acid in a cool, dry place away from incompatible substances such as strong bases and oxidizing agents.

In the food industry, diluted acetic acid is commonly used as a preservative and flavoring agent. It is the primary ingredient in vinegar, which is utilized in food preservation and culinary applications. Additionally, in the agricultural sector, acetic acid can act as a herbicide, helping to control weeds in organic farming practices.
