[0020] Unreacted free sugar 30.1
[0021] Soap body 13.5
[0022] Fatty acids 3.8
[0023] Fatty acid methyl esters 2.7
[0024] Impurities such as catalysts 1.9
[0025] The monoester content of sucrose ester is 50.2%, the diester is 30.1%, and the polyester is 19.7%.
[0026] To 100 g of the above crude sucrose ester A, add 380 ml of butanone (c, p) and 220 ml of 8% Nacl aqueous solution, stir the mixture at 35° C. for 25 minutes, and separate the water layer. Adjust the pH to 5.9±0.3 with dilute sulfuric acid at 55°C, stir for 12 minutes, and remove the lower aqueous layer. Use anhydrous sodium sulfate to remove excess water in the organic phase, add 1 g of calcium oxide to the organic phase under stirring at 45°C for 40 minutes, filter and evaporate the clear li...
