摘要
以改性 HZSM-5沸石催化剂用于甲苯-乙醇的烷基化反应,在常压和350℃下得到不含邻位异构体的间、对甲基乙苯,继而在315铁系催化剂上于630℃脱氢,得到间、对甲基苯乙烯(其中对位占60%,间位占40%)。该产品可用作塑料闪烁体载体。
For alkylation of toluene-ethanol a denatured HZSM-5 zeolite was used ascatalyst to obtain m-and p-methyletylbenzenes free of the o-isomer underordinary pressure and at 350℃;m-and p-methylstyrenes in proportions of 40%and 60% respectively were then prepared by dehydrogenation at 630℃ over Fe-catalysts.The products may be used as carrier for plastic scintillators.
