14synthesis methods
-

Yield:105-70-4 60%

Reaction Conditions:

at 120; for 4 h;High pressure;Inert atmosphere;

Steps:

1
Adding 15g (0.25mol) of acetic acid, 2.3g (0.025mol) of glycerol and 0.023g of catalyst to the high pressure reaction of stainless steelIn the kettle, under the protection of an inert gas, the reaction was stirred at 120 ° C for 4 hours under normal pressure. After the reaction was completed, the catalyst was centrifuged, and the reaction solution was centrifuged.After filtration through a 0.22 μm filter, the glycerin conversion and the yield of diacetin were measured by gas chromatography, and the results are shown in Table 1.
