【Abstract】 The synthetic reaction of isolongifolene isomerized directly from heavy turpentine oil was studied.The suitable compound catalyst was selected and the corresponding reacting conditions were studied.The optimum conditions were determined as follows:the compound catalyst was Y harmoniously combined with H2SO4;the dosage of Y was 10%(mass fraction) of the mass of heavy turpentine oil,and the dosage of H2SO4 was 3%(mass fraction) of the mass of heavy turpentine oil;the reaction temperature was 65～75℃ and the reaction time was 3.5h.On the above conditions the yield of isolongifolene was 83.9%.更多还原
