Abstract:Fructone - B was synthesized sing silicotungstic acid catalyst absorbed on activated carbon from ethyl ace-toacetate and 1,2 - propylene glycol with the recovery of 95% . The effects of ratio of reactants, reaction time, quantity of catalyst were discussed. The results show this catalyst has high catalytic activity, good chemical stability, good repeatability and little waste discharged.
Keywords:Fructone - B  Silicotungstic acid  Catalyst  Synthesis
