Process for preparing diarylamines from arylamines |
| abstract |
A process for preparing diarylamines in high yield, in which diarylamines are prepared from arylamines in the presence of a solid acid catalyst. The solid acid catalyst with good stability and regeneration ability consists of H-type beta zeolite and active alumina, the ratio of SiO2/Al2O3 in the zeolite is 20 DIFFERENCE 100, and the content of active alumina is 10% DIFFERENCE 70% (wt). |
