Abstract: 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 ¹H 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.
