摘要
采用活性粘土代替传统的无机强酸作催化剂,苯胺和N,N'-二甲基苯胺分别与甲醛和苯甲醛缩合得到对应氨基苯甲烷产物。结果表明,活性粘土的催化效果好,而且简化了合成工艺,生产过程也无腐蚀。
The condensation products of aniline, N,N'-dimethylaniline with formaldehyde, benzaldehyde have been respectively prepared with active clays as catalysts instead of inorganic acids. The results show that the catalystic effect is better and the prepared procedure is simpler than the tradition one. It is non-corrosive in industrial production.
