摘　　要：采用阳离子交换树脂催化莰烯水合反应所制得的粗异龙脑中含较少的葑醇和３－莰醇，最主要的副产物是水合莰烯。在酸性催化剂硼酸的存在下，水合莰烯发生脱水变成莰烯而易被从樟脑中分离出去，因此可得到纯度９８％以上，烙点高达１７６～１７９℃的高质量的樟脑。本文报道制取高纯度樟脑过程的合成路线、产物、樟脑纯化以及物料平衡方面的研究结果。Using cation exchange resin as the catalyst of camphene hydration,isoborneol,camphene hy-drate,small amount of 3-camphanol and fenchols are obtainted.The main impurity is carnphene hydrate.In the presence of H_3BO_3,the camphene hydrate dehydrates and becomes camphene which can be easilyseparated from camphor.The purity of camphor is 98%or more in the final product and the m.p. canreach 176～179℃. In this article,the synthesizing process,the results of purifing camphor and the mate-rial balance were reported.
