| titleOfInvention | A kind of preparation method of aromatic amine compounds |
| abstract | The invention discloses a kind of preparation methods of aromatic amine compounds, and steps are as follows: (1) organosilan and aromatic nitro compound being added into alcohols solvent, nano porous palladium silver alloy catalyst is added, in 20~80 DEG C of 1~3h of reaction；(2) method for utilizing column chromatography for separation, purified product obtain corresponding aromatic diaminodithiol compound.This method uses heterogeneous palladium-silver catalyst, can in normal pressure, realize under room temperature and go back original aromatic nitro compound and prepare aromatic amine compounds；Using nano porous palladium silver alloy catalyst, the hydrogen transfer reaction that aromatic amine compounds are prepared using the hydrogen that silane oxidation generates is realized, while the catalyst performance is more stable, can reuse, to reduce costs；The preparation method has high-activity high-selectivity, and yield is high, and yield avoids the problem of traditional preparation methods need the harshness reaction condition such as high temperature or high pressure up to 95%. |
