dioli

Dioli is the Italian plural form of diolo, a term used in chemistry to describe diols, organic compounds that contain two hydroxyl groups (-OH). The English equivalent is diol; in Italian literature you will often see dioli used for these compounds.

In chemistry, a diol is characterized by two hydroxyl functional groups. They can be classified by the positions of the hydroxyl groups, such as geminal diols (two -OH on the same carbon) and vicinal diols (two -OH on adjacent carbons). Common examples include ethylene glycol (ethanediol) and propylene glycol (propanediol). Diols are widely used as solvents, in the preparation of polyesters and polyurethanes, as plasticizers, and in antifreeze formulations. Their synthesis often involves oxidation of glycols or hydration and substitution reactions of carbonyl compounds.

Dioli is also a surname of Italian origin. It appears in Italian records and in communities descended from Italy. The surname is relatively uncommon, and individuals bearing it may be found in various professions and regions.
