Study on preparation and properties of lacti-glyceride
Lacti-glyceride were synthesized by Lactic and Glycerol and its properties of moisture retention and hygroscopicity were investigated. The optimum conditions of the reaction were determined as following: Toluene was used as dehyator, amount of catalyst: 7.94 wt%, reaction time: 3h. The properties of production such as moisture retention and hygroscopicity of Lacti-glyceride were determined .The result is that moisture of Lacti-glyceride is better than Glycerol but hygroscopicity is within an inch of Glycerol.
