| Abstract: | The paper presents a method for producing carboxymethylinulin(CMI) in ethanol.The preparation conditions of carboxymethylinulin were determined by single factor tests and orthogonal experiments.The best CMI with a DS of 0.79 was produced via etheriifcation of a mixture of inulin,sodium hydroxide,chloroacetic acid(mole ratio=1:2.5:1.5) in 0.95%(V/V) ethanol(40 mL) at 50℃ for 3 h,and alkalization at 35 ℃ for 0.5 h. |
