用氨基钠还原剂合成香料乙基柏木醚

Synthesis of Perfume Cedryl Ethyl Ether Using Aminosodium Reducing Agent

柏木醚是柏木醇的脂肪族醚。由柏木油中提取的柏木醇３２ｇ、１７６ｍｌ二甲苯、氨基钠７ｇ，在１１５～１２５℃下回流２ｈ，冷却，慢慢滴加３２ｇ硫酸二乙酯，在１１５～１２５℃回流１ｈ，分馏，在１１３～１１４℃／０．１６ｋＰａ下收集乙基柏木醚，产率８９％，含量９６％。

Cedryl ether is one of the cedar series perfumes with high quality fragrance.It is an aliphatic ether of the cedrol.32g cedrol extracted from cedar wood oil,176ml dried dimethyl benzene and 7g aminosodium,the reactants were refluxed for 2h at 115～125℃. After cooling the mixture,32g diethyl sulfate was slowly added dropwise into it, and refluxed for 1hr at 115～125℃.The fraction at 113～114℃/0 16kPa was collected as the product.The yield of cedryl ethyl ether was 89%.The product has a cedryl ethyl ether content of 96%.
