Glycerin formal is a chemical compound that is liquid at room temperature. It consists of a 60:40 mixture of 5-hydroxy-1,3-dioxane and 4-hydroxymethyl-1,3-dioxolane . It is used as a synthesis component or as a solvent on a biogenic basis.

Manufacturing

Glycerine formal is obtained synthetically from glycerine and formaldehyde .

Chemical properties

Glycerin formal consists of a mixture of 5-hydroxy-1,3-dioxane and 4-hydroxymethyl-1,3-dioxolane which are in equilibrium with one another. The equilibrium between the isomers takes place via the open-chain form of the hemiacetal and is comparable to the mutarotation of carbohydrates .

The isomer 4-hydroxymethyl-1,3-dioxolane has a center of chirality and therefore occurs as a pair of enantiomers .

use

It is used as a synthesis component in the chemical and pharmaceutical industries. It is also considered a biogenic solvent in so-called green chemistry .
