本文研究了异龙脑气相催化脱氢生成樟脑过程，筛选出催化剂金属氧化物CDH。反应温度在240℃时，催化剂CDH有良好的选择性和较高的反应活性、稳定性。本实验结果：樟脑产率达96％，樟脑纯度为98％（熔点176℃）。
In this paper, the isomerising process of gas phase catalytic dehydrogenation of camphor was studied, and the catalyst metal oxide CDH was screened out. When the reaction temperature is 240 ℃, the catalyst CDH has good selectivity and high reactivity and stability. The results of this experiment: 96% camphor yield, camphor purity of 98% (melting point 176 ℃).
