摘要
考察了将C_(10)芳烃中四甲苯异构化制备均四甲苯的工艺,通过自制催化剂,使C_(10)重芳烃中的均四甲苯质量分数显著提高,达到或超过其平衡组成。最佳反应条件:反应温度305℃,反应压力2 MPa,空速1．4 h^(-1)。
A method for the preparation of durene by isomerization of tetramethylbenzene was reported. Using self-made catalyst, the durene content in C10 aromatic hydrocarbons reached or even excee- ded the equilibrium concentration. The optimal reaction conditions were found as follows, reaction temperature 305℃ ,pressure 2 MPa and space velocity 1.4 h^-1.
