| 摘 要：以催化重整C9芳烴分離裝置分離出均三甲苯、偏三甲苯后的副產(chǎn)品重組分溶劑(169～178℃餾分)—混合C9芳烴為原料,其中含連三甲苯40%～50%,以三氯化鋁為催化劑與異丁烯進(jìn)行烷基化反應,合成出5 叔丁基 1,2,3 三甲基苯中間體,經(jīng)蒸餾后,用混酸進(jìn)行硝化反應得到西藏麝香。本方法不但具有工藝路線(xiàn)簡(jiǎn)單,生產(chǎn)成本低的特點(diǎn),同時(shí)也解決了富集連三甲苯的利用問(wèn)題。 |

| Abstract：In this process , the heavy fraction solvent (169～178℃)— mixed C_(9) aromatic hydrocarbon, namely, the by-product of mesitylene and pseudocumene which were separated from C_(9) aromatic hydrocarbon catalytic reforming separation facility , will be the feedstock which was alkylated by isobutene in presence of aluminium trichloride as catalyst to synthesize 5-tert-butyl-1,2,3 trimethyl benzene intermediate product which , after distillation ,was nitrated with nitro-sulfuric acid to obtain Musk Tibetene. This ... |
