【摘要】 以油酸和三羟甲基丙烷(TMP)为原料,用SnCl2.2H2O作催化剂,通过减压酯化的方法合成了三羟甲基丙烷油酸酯。反应的优化条件如下:n(油酸)n∶(TMP)=3.11∶,催化剂用量4%,反应温度170℃,反应时间4h,真空度0.09MPa。优化条件下TMP的酯化率达到94%。产物结构经IR光谱证实。更多还原

【Abstract】 Oleic acid trimethylolpropane ester was synthesized from esterification of oleic acid and trimethylolpropane under reduced pressure with SnCl2·2H2O as catalyst.The optimum conditions were found as follows: n(oleic acid)/n(trimethylolpropane) was 3.1,amount of SnCl2·2H2O 4%(based upon mass percent oleic acid),reaction for 4 h at temperature 170℃ and vacuum degree 0.09 MPa.In the optimum conditions,the conversion rate of trimethylolpropane was 94%.The structure of product was identified by IR.更多还原
