Reaction Conditions:

at 150; for 0.5 h;

Steps:

1 example 1

the acetic acid (boiling point 117 ° C) mixed acid is gasified by a fatty acid pre-heater and from the bottom enter into the esterification kettle, so that acetic acid gas filling the kettle, the kettle temperature control at 150 ° C, then the catalyst and glycerol stirred in a premixed pot for 30 min, after that pass through the atomizer from the top of the bottle, and put the acetic acid into the kettle in the presence of atmospheric pressure, the reaction time will be 40min, during the reaction, the acetic acid gas is continuously passed, and after the completion of the reaction, the acetic acid gas is stopped, and the reactant is discharged from the outlet. The esterified product is a colorless, clear oily liquid, acid value (mg KOH/g) is 0.09, Triacetate triglyceride content 99.5%.
