Benzoatos

Benzoatos refers to the salts or esters of benzoic acid. Benzoic acid itself is a simple aromatic carboxylic acid with the formula C6H5CO2H. As salts, benzoatos are formed when the acidic hydrogen of benzoic acid is replaced by a metal cation, such as sodium (forming sodium benzoate) or potassium (forming potassium benzoate). These salts are typically soluble in water and are commonly used as preservatives in food and beverages. They inhibit the growth of mold, yeast, and some bacteria, thus extending the shelf life of products.

Esters of benzoic acid, also referred to as benzoatos, are formed through a reaction between benzoic acid and an alcohol. These compounds have a wide range of applications, including use as solvents, plasticizers, and in the fragrance industry. For example, benzyl benzoate is an ester used as a medication to treat scabies and lice, as well as a fixative in perfumes. The specific properties of benzoate esters vary depending on the alcohol group attached to the benzoate moiety, influencing their volatility, solubility, and reactivity. The term "benzoatos" is a general chemical classification encompassing both the ionic salts and the organic ester derivatives of benzoic acid.
