The hydrogenation of ethyl p-tolyl ether (1) in ethanol has been studied with five unsupported platinum metals as catalysts, mainly with the purpose of estimating the yields of ethyl 4-methyl-1-cyclohexenyl ether (2) formed as intermediate. Except for ruthenium catalyst, the hydrogenation of 1 in ethanol was accompanied by the formation of acetal 3, ketone 4 and alcohol 5 which seem to be related to
用五种未负载的铂金属作为催化剂研究了乙基对甲苯基醚 (1) 在乙醇中的氢化,主要目的是估计作为中间体形成的 4-甲基-1-环己烯基醚 (2) 的产率。除钌催化剂外,1在乙醇中的加氢伴随着缩醛3、酮4和醇5的形成,这似乎与2的形成有关。从催化剂中解吸的2和相关化合物的量通过应用动力学和外推方法,估计表面为 Ru 32-33%,Rh 32-34%,Pd 72-76%,Ir 3.7% 和 Pt 4.7%。两种方法的结果之间获得了很好的一致性。催化剂金属的氢解比例按Pd顺序增加
