以甲苯、乙苯、异丙苯、间二甲苯和均三甲苯为原料,在由路易斯酸、有机酸和无机酸所组成的新型复合催化剂协同催化下,经多氯甲基化反应制备了2,4,6-三(氯甲基)甲苯、2,4,6-三(氯甲基)乙苯、2,4,6-三(氯甲基)异丙苯、2,4,6-三(氯甲基)间二甲苯和2,4,6-三(氯甲基)均三甲苯。利用IR、~1H NMR、~(13)C NMR等手段对所合成产物的结构进行了表征,在优化反应条件下,5种产物的收率分别可达24.5%、31.7%、15.3%、78.1%和89.6%。
With toluene, ethylbenzene, cumene, m-xylene and mesitylene as raw materials, Lewis acid, organic acids and inorganic acids consisting of a new composite catalyst synergistic catalysis, prepared by the chloromethylation 2 , Tris (chloromethyl) toluene, 2,4,6-tris (chloromethyl) ethylbenzene, 2,4,6-tris (chloromethyl) cumene, Tris (chloromethyl) m-xylene and 2,4,6-tris (chloromethyl) mesitylene. The structures of the synthesized products were characterized by means of IR, 1H NMR and 13 C NMR. The yield of the five products reached 24.5%, 31.7%, 15.3% and 78.1 % And 89.6%.
