摘　　要：用硼酸与异龙脑的异构化产物—龙脑、异龙脑和樟脑的混合物进行反应，得到硼酸莰酯和樟脑。莰酯与樟脑分离后，经水解得到龙脑和异龙脑。A mixture of borneol (isoborneol ) and camphor can be separated by esterification withboric acid. The volatility of borneol (isobmeol) borate is much lower than that of camphor, sothey can be separated by subime , Then the hydrobyzation of the borate will give back borneol(isoborneol).
