混合C_9芳烃与异丁烯烷基化制备均三甲苯的研究

Study of mesitylene preparing by alkylation of mix C_9 aromatic hydrocarbon and isobutene

混合C9芳烃与异丁烯烷基化制备均三甲苯,混合C9芳烃中的邻甲乙苯可生成重组分,利用精馏方法除去这些重组分,可得到满足工业要求、纯度为98.5%的均三甲苯产品。

When preparation of mesitylene by alkylation of mix C9 hydrocarbon with isobutene, the methyl ethyl benzene in mix C9 can be transferred to heavy component. Purity of 98.5% of mesitylene for industry use can be obtained by removing heavy component with rectification.
