摘要
苯胺气相Ｎ－烷基化反应研究Ⅱ．苯胺和乙醇常压催化合成Ｎ－乙基苯胺的工业应用陈骏如，李瑞祥，韩银仙，李贤均（四川大学化学系成都６１００６４）Ｎ－乙基苯胺是制造染料、塑料、炸药和医药等许多化工产品的重要中间体，其合成方法过去多采用无机酸催化剂，如Ｈ＿２Ｓ...
Industrial Production of N-cthylaniline and N,N-diethylaniline using solid acid as catalyst has been developed. When the reaction is carried out under the conditions:vapor phase,atmospheric pressure,T=295-305℃’C_6H_5NH_2/C_2H_5OH=1:2 mole ratio),LHSV=0. 6h￣(-1) ,the conversion of aniline is about 80-85%and the selectivity for N-ethytaniline is about 82-86%,The another product is N. N-diethylaniline.
