摘要：以光皮树果油(WFO)和橡胶籽油(RSO)为原料,采用过氧乙酸法制备环氧化光皮树果油(EWFO)和环氧化橡胶籽油(ERSO),并以四氟硼酸为催化剂,乙二醇为羟基化试剂,对EWFO和ERSO进行羟基化改性制备羟基化光皮树果油(HWFO)和羟基化橡胶籽油(HRSO)。正交试验结果表明:EWFO的最佳制备工艺为WFO原料质量30 g,乙酸用量11 g,双氧水用量23 g,浓硫酸用量0.4 g,反应时间2 h,反应温度65℃,此条件下制备的EWFO的环氧值可达4.13%。以产物羟值为考察目标,对EWFO和ERSO羟基化条件进行优化,结果表明:m(乙二醇)∶m(ERSO)=3∶1,催化剂用量1%,90℃反应2 h的优化条件下,HRSO的羟值可达241.1 mg/g;催化剂用量1%,m(乙二醇)∶m(EWFO)=2∶1,100℃反应2 h的优化条件下,HWFO的羟值可达179.7 mg/g。FT-IR和1H NMR分析结果表明:在上述实验条件下,环氧化和羟基化反应均顺利进行,得到了相应的环氧化木本油脂和羟基化木本油脂。
The epoxidized wilsoniana fruit oil(EWFO)and epoxidized rubber seed oil(ERSO)were prepared by peracetic acid method from wilsoniana oil(WFO)and rubber seed oil(RSO).The hydroxylation of EWFO and ERSO were carried out to obtain hydroxyl wilsoniana fruit oil(HWFO)and hydroxyl rubber seed oil(HRSO)using tetrafluoroborate as catalyst,and ethylene glycol as the hydroxyl reagent.The results of orthogonal test showed that the optimum preparation process of EWFO was as followed:the weight of WFO 30 g,the amount of acetic acid 11 g,the amount of hydrogen peroxide 23 g,the amount of concentrated sulfuric acid 0.4 g,the reaction time 2 h,the reaction temperature 65℃,and the epoxy value of the EWFO could reach 4.13%.The conditions of hydroxylation of EWFO and ERSO were potimized based on the hydroxy value of hydroxylation products.The results showed that the hydroxy value of the HRSO could reach 241.1 mg/g under the conditions of m(ethylene glycol)∶m(ERSO)=3∶1,the amount of catalyst 1%,90℃ and 2 h;the hydroxy value of HWFO could reach 179.7 mg/g under the conditions of m(ethylene glycol)∶m(EWFO)=2∶1,the amount of catalyst 1%,100℃and 2 h.FT-IR and 1^H NMR analyses indicated that the epoxidation and hydroxylation reactions were carried out successfully under the above experimental conditions,and the corresponding epoxy woody oil and hydroxyl woody oil were obtained.
