【摘要】 以碱性皂为乳化剂和催化剂,在(125±1)℃、反应物料物质的量之比1∶1,真空度0.090MPa及无溶剂的条件下,通过氢化松香乙酯与蔗糖的酯交换反应合成了氢化松香蔗糖酯(HRSE)。用TLC、IR、UV、HPLC、HPLC-MS、13CNMR等多种方法对产物进行了分析和表征,并测得产物的临界胶束浓度(CMC)为0.009mol/L,此时的表面张力为47mN/m。更多还原

【Abstract】 In the presence of alkaline soap as emulsifier and catalyst, hydrogenated rosin sucrose esters (HRSE) were synthesized by transesterification reaction of hydrogenated rosin ethyl ester and sucrose under the conditions of (125±1)℃,molar ratio of hydrogenated rosin ethyl ester to sucrose 1 ∶1, pressure 0.090 MPa without solvent.The target product was analyzed and characterized by TLC, IR, UV, HPLC, HPLC-MS and 13C NMR. Besides, critical micelle concentration (CMC) and the corresponding surface tension of the target product were measured to be 0.009 mol/L and 47 mN/m, respectively.更多还原
