摘　　要：以α-蒎烯为主要原料,双氧水经浓缩后再和冰乙酸反应制得过氧乙酸,用自制的过氧乙酸氧化α-蒎烯,高选择性地制备2,3-环氧蒎烷.通过体系预冷至-15℃的方法,容易控制反应温度,确定适宜的反应条件为:m(无水碳酸钠)∶m(α-蒎烯)=0.7,m(过氧乙酸)∶m(α-蒎烯)=3,氯仿为溶剂,在15℃下反应6 h.在此条件下,α-蒎烯的转化率达到99%,2,3-环氧蒎烷的选择性达到95%.Peracetic acid was synthesized by reaction of acetic acid with pre-concentrated hydrogen per- oxide. Then the self-madeperacetic acid was used to oxidize α-pinene to synthesize 2,3-epoxypinane with high selectivity. The reactions were easier to control by precooling the system to 15 ℃. At the condition of m（ Na2CO3 ） ： m （ot-pinene） = 0. 7, m （CH3CHOOOH） ： m （α-pinene） = 3, chloroform as the solvent, 15 ℃,6 h, the conversion rate of α-pinene was above 99 %, and the selectivity of 2,3-epoxypinane was about 95 %.
