clear liquid | [Uses]
Diacetin has been used to design and evaluate gliclazide push-pull osmotic pump (PPOP) coated with aqueous colloidal polymer dispersions. | [Uses]
Diacetin is used as a solvent, plasticizer, and softening agent. | [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. |
