冰片基氯与钠、氧反应,再水解制成冰片的方法
Abstract:
冰片基氯与钠，氧反应再水解制成冰片的方法是这样的：松节油中的a蒎烯与乾燥的HCI气体反应，得到冰片基氯，收率为85％-90％，往后是把它与钠反应，生成冰片基钠，冰片基钠在专用设备中与氧气反应，生成冰片基氧合钠，酸性水解冰片基氧合钠即得合成冰片，此法所得产品中的龙脑含量≥85％，高出中国药典要求30个百分点之多。预计本发明的生产成本要比现行方法下降20％-25％，此外成品的优良品质还能带来销售价增长≥25％的升值效果。？
Abstract(English):

The invention relates to a method for preparing borneol by hydrolyzing after the reaction of bornylchloride and sodium and oxygen, comprising the following steps of: reacting alpha pinene in turpentine with dry HCL gas to obtain the bornylchloride, wherein the yield is 85%-90%; then reacting the bornylchloride with the sodium to generate bornylsodium; reacting the bornylsodium with the oxygen in special equipment to generate bornyl-oxygenated sodium; and then carrying out acidic hydrolysis on the bornyl-oxygenated sodium to produce the borneol. The borneo camphor content of the product obtained by the method is not less than 85% and is over 30% higher than the requirement of the Chinese pharmacopoeia. The production cost of the method is 20%-25% lower than that of the current method; in addition, the fine quality of the finished product can also bring the appreciation effect that the selling price is increased not less than 25%.
