EC / List no.: 246-941-2
CAS no.: 25395-31-7
Mol.Formula: C7H12O5
Description
Contains 1,2-diacetin, 1,3-diacetin and triacetin.
A useful plasticizer.
Also a useful chemical to design and evaluate gliclazide push-pull osmotic pump (PPOP) coated with aqueous colloidal polymer dispersions.
Diacetin is widely used as plasticizer.
Glyceryl diacetate is a food additive with the E number E1517.
This diglyceride is more generally known as diacetin.
It is the diester of glycerol and acetylating agents, such as acetic acid and acetic anhydride.
It is a colorless, viscous and odorless liquid with a high boiling point.
Glycerol diaceate is typically a mixture of two isomers, 1,2-glyceryl diacetate and 1,3-glyceryl diacetate.
Use
Diacetin is used as a solvent, plasticizer, and softening agent.
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).
