Abstract: In this paper, the synthetic technique of low calorie safflower oil sucrose esters to replace single aliphatic acid bymethyl ester of safflower oil was studied. The effects of reaction temperature, quantity of catalyst and emulsion consumptionon the result of reaction were discussed, and the optimum process conditions of synthetic reaction were assayed. It was shownthat: catalyst C was 3%(W%), emulsion consumption 8%(W%), reaction temperature 130℃ and reaction time 3.5~4.5h. Theconversion rate of methyl ester of safflower oil has thus been attained as 87.70%. The oil-soluble sucrose ester produced was 61.25%(W%); surface intension 30.6mN/m; detersive power 84.7%; degreasing power 34%; steady foam power 8.0/6.0mm/mm(after 5mins); and HLB 12.5.
