Glycerine acetate explained

Glycerine acetate is a mixture of esters produced from the esterification of glycerol (1) with acetic acid. This reaction produces five congeners:

• the two monoacetylglycerols / MAG / monoacetin (2 and 3)
• the two diacetylglycerols / DAG / diacetin / glyceryl diacetate (4 and 5)
• the one triacetalglycerol / TAG / triacetin (6)

In addition, two of the congeners, 2 and 4, are chiral and can exist in either of two enantiomeric forms.

Uses

DAG and TAG can be used as fuel additives for improving the cold and viscosity properties of biodiesel or the antiknocking properties of gasoline.^[1]
