Diacetin Usage And Synthesis

Chemical Properties

clear liquid

Uses

Diacetin is used as a solvent, plasticizer, and softening agent.

Uses

Diacetin has been used to design and evaluate gliclazide push-pull osmotic pump (PPOP) coated with aqueous colloidal polymer dispersions.

Definition

ChEBI: A diglyceride resulting from the formal condensation of any two of the hydroxy groups of glycerol with the carboxy groups of two molecules of acetic acid (either R1 = H and R2 = Ac, or R1 = Ac and R2 = H).

General Description

Diacetin is widely used as plasticizer.

Synthesis

Prod.:
1) from Glycerin with 2 mol. Acetic acid.
2) from AHYIacetate uith Hypoiodous acid, followed by reaction with Potassium acetate.
