N-(2-丙氧基乙基)-2,6-二乙基苯胺是除草剂丙草胺的重要中间体,其合成方法有:1)2,6-二乙基苯胺与溴乙基丙基醚或氯代乙基丙基醚反应合成;2)2,6-二乙基苯胺与乙二醇单丙醚直接烷基化反应合成。第1种方法存在着单烷基化选择性不高的问题;而第2种方法需贵金属催化剂及高温、高压等反应条件。芳香胺的N-烷基化还可以通过芳香胺与醛或酮 N- (2-propoxyethyl) -2,6-diethylaniline is an important herbicide intermediates, its synthesis method: 1) 2,6-diethyl aniline and bromoethyl Propyl ether or chloroethyl propyl ether synthesis; 2) 2,6-diethyl aniline and ethylene glycol monopropyl ether direct alkylation synthesis. The first method has the problem of low selectivity of monoalkylation. The second method requires noble metal catalysts and reaction conditions such as high temperature and high pressure. N-alkylation of aromatic amines can also be by aromatic amines with aldehydes or ketones
