【摘要】 以对甲苯磺酸为催化剂,油酸和1,3-丙二醇为原料合成了1,3-丙二醇油酸双酯。最佳反应条件为:油酸60 mmol,n(油酸)∶n(丙二醇)=2.1,催化剂对甲苯磺酸的用量为油酸质量的3.5%,带水剂甲苯20 mL,于160℃反应1 h。在优化反应条件下,酯化率98%,收率77%。更多还原

【Abstract】 1,3-Propanediol bisoleate were synthesized from oleic acid and 1,3-propanediol using p-toluene sulfonic acid as the catalyst.The optimal reaction conditions at 160 ℃ for 1 h were as follows: oleic acid was 60 mmol;n(oleic acid) ∶n(1,3-propanediol) was 2.1;w(p-toluene sulfonic acid)=3.5%(upon mass percent of oleic acid);toluene was 20 mL.The conversion of 1,3-propanediol was 98% and the yield was 77% under the optimal reaction conditions.更多还原
