Abstract: Green chemical product - safflower oil sucrose have been are obtained by two-step approach. By means of orthogonal experiment, the optimum conditions of synthesis of sucrose fatty acid esters were obtained: sucrose: safflower oil fatty acid esters =1:0.8 (mol:mol), fatty acid soap 15% (wt), catalyst 2%, reaction temperature 135℃, reaction time 2h and reaction pressure≤5mmHg. Through analysis of TLC, the results showed that product was made of sucrose monoesters and sucrose diesters. SE structure was confirmed by IR spectroscopy with yields 60%.

Key words: safflower oil sucrose esters, interesterification, green chemistry
