Abstract: Green synthetic method of allyl isobornyl ether was investigated by using camphene and allyl alcohol as the raw materials in this paper. Influence of catalysts and their usages， reaction temperature， reaction time， and the molar ratio of allyl alcohol to camphene on the selectivity of etherification and the yield of allyl isobornyl ether were examined， and the optimum synthesis conditions were determined based on the orthogonal test results as follows： A15 resin was used as the catalyst for etherification， and the amount of A15 cationic exchange resin was 5 ％ （based on the total weight of camphene and allyl alcohol）； molar ratio of allyl alcohol to camphene was 15〖DK〗∶1； reaction temperature and reaction time were 75 ℃ and 7 h， respectively. The conversion ratio of camphene and the reaction selectivity reached 855 ％ and 975 ％ respectively， and the yield of allyl isobornyl ether also reached 834 ％. The structure of allyl isobornyl ether was identified by GCMS and IR spectra.
