中文摘要：

以2，3-环氧蒎烷为原料，在无溶剂的条件下以ZnCl2为催化剂进行重排合成龙脑烯醛。研究结果表明，ZnCl2用量为环氧蒎烷的4％，在80℃下反应1h时，2，3-环氧蒎烷的转化率达99．19％，龙脑烯醛的选择性达到74．33％；以MCM-41、自制SO4-ZrO2-MCM-41为催化剂进行无溶剂重排，2，3-环氧蒎烷的转化率分别达到98．01％、89．40％，选择性分别为63．46％和48．96％。

英文摘要：

An experiment was conducted to synthesize eampholenic aldehyde by rearrangement of 2,3-pinene oxide under solvent free conditions. Results showed that the conversion rate of 2,3-pinene oxide was 99.19% and aldehyde selectivity was up to 74.33% when 4% ZnC12（the mass of 2,3-epoxypinane） was used, reacting at 80 degrees C for 1 hour under the sol- veto-free conditions. The conversion rates of 2,3-epoxypinane were 98.01% and 89.4% , and the selectivity to camphene was up to 63.46% and 48.96% respectively when MCM-41 or SO4-ZrO2-MCM-41 was taken as the catalyst, rearranging at 80 degrees C for 1 hour under the solvent-free conditions.
