Catalytic Synthesis of Ethylene Glycol Stearate by Silicotungstic Acid Immobilized on Ion Exchange Resin
2009
Silicotungstic acid Immobilized on ion exchange resin as a catalyst,ethylene glycol and stearic acid as raw materials,Synthesis of glycol stearate.Influecing on the yield of reaction craft like the type of ion exchange resin,the amount of catalyst,reaction time,with the type and amount of water-carrying agent,molar ratio of glycol to acid was investigated.The results showed that the amount of catalyst was 25%,reaction time was 4.5h,the molar ration of alcohol to acid was 3.0:1,cyclohexane was 10mL.The conversion of acetic acid was 94%,and the catalyst can be reused.
