【摘要】 <正>龙脑分为内向构型的正龙脑和外向构型的异龙脑,其中,正龙脑是许多名贵中成药的主要成分。天然龙脑价格昂贵,用合成龙脑代替天然龙脑是发展趋势。本研究以铝片为阳极,石墨为阴极,以异丙醇为溶剂,四丁基溴化铵为支持电解质,用电还原樟脑来制备龙脑。电解结束后,将电解液倒人过量水中,用乙醚萃取产品,醚液用无水硫酸钠干燥,过滤后减压蒸去乙醚即得龙脑。反应机理如下:更多还原

【Abstract】 Electro-generation of bomeol using camphor as raw material was studied.The aluminum anode and the graphite cathode were used.The effections of reaction time, temperature and the content of conduct salt on the experimental result were discussed.The results showed that the yield of bomeol was 40.0%,in which the yield of bomeol and isoborneol were 31.3%and 8.7%respectively at 40℃for 8h.更多还原
