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%。 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 fol- lows: 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.
