摘要
以混合C9芳烃(169-178℃馏分)为原料,其中含连三甲苯40％-50％,以三氯化铝为催化剂与异丁烯进 行烷基化反应,合成出5-叔丁基-1,2,3-三甲基苯中间体,经蒸馏后,用混酸进行硝化反应得到西藏麝香。本方法不但具 有工艺路线简单、生产成本低的特点,同时也解决了富集连三甲苯的利用问题。
In this process , the heavy fraction solvent (169-17℃)--mixed C9 aromatic hydrocarbon, is
alkylated by isobutene in presence of aluminium trichloride as catalyst to synthesize 5-tert-butyl-l ,2,3-trimeth-yl benzene intermediate product. The intermediate , after distillation , is nitrated with nitro-sulfuric acid to obtain musk tibetene. This method is low cost and simple in design , and the pregnant hemimellitene is fully used in this process.
