Abstract: A new kind of surfactant, i.e. starch fatty acid esters, was prepared with nature soybean oil and starch as raw materials in this paper. The reaction conditions were studied with response surface methodology design. A reaction model and the optimum conditions were got as the results. The optimum synthesis conditions were as follows: the reaction time of 11.6 h, reaction temperature of 56.3 ℃, catalyst of 1.14% and ratio of starch to fatty acid methyl esters of 1:14(W/W). The substitute degree of product was up to 0.10683.

Key words: starch fatty acid esters, synthesis, response surface methodology
