摘　　要：　研究了蒎烷的氧化反应,实现了用空气代替纯氧气进行氧化以制备蒎烷氢过氧化物(PHP)的设想。蒎烷的空气氧化反应需要用催化剂;反应时间约在25h左右,比用纯氧氧化延长了3～5h;反应温度一般控制在110℃以内,与纯氧氧化温度类似。在空气氧化蒎烷得到的产物中,PHP含量一般可达到45%～50%,与用纯氧氧化的结果相当。氧化产物进行常压催化加氢所得还原产物粗蒎醇用GC分析的结果表明,其蒎醇含量(超过38%)及主要产物组成与用纯氧氧化所得产物基本一致。在回收蒎烷中含较多反式蒎烷。实验结果表明,空气氧化工艺有可能代替纯氧氧化工艺应用于合成PHP的工业生产。Air oxidation process of pinane was studied to prepare pinane hydroperoxide(PHP),instead of using pure oxygen.The reaction occurred smoothly at the presence of a catalyst,taking about 25 h that is a little longer(about 3-5 h) than that of pure oxygen oxidation process,and oxidation temperature was below 110 ℃,similar to the latter process.Content of PHP in the crude product is about 45%-50%.Content(more than 38%) of pinols and the composition of the reaction product are about similar in both catalytic air oxidation and pure oxygen oxidation based on GC analysis of crude pinanol that is derived from reduction of PHP by catalytic hydrogenation under atmospheric pressure.However,there is more transpinane in the recovered pinane than in the fresh material.It is concluded that catalytic air oxidation process could be industrialized to produce PHP instead of pure oxygen oxidation process.
