| titleOfInvention | The method that paranitrobenzaldehyde catalytic hydrogenation prepares para aminotenzaldehyde |
| abstract | The present invention discloses a kind of method that paranitrobenzaldehyde catalytic hydrogenation prepares para aminotenzaldehyde.The method of the present invention is first to add paranitrobenzaldehyde in a kettle., adds ethanol and loaded catalyst, and closed reactor, with the air in the complete replacement reaction kettle of hydrogen, then keeps in kettle being normal pressure（0.1MPa）And begin to warm up stirring, temperature is passed through hydrogen in kettle after reaching 60 DEG C, kettle internal pressure power is set to remain to 1.0~3.0MPa, start hydrogenation reaction, conversion ratio is to reach 88~90% after being hydrogenated with about 0.5 to 1.5 hour, is then demultiplex out reactant mixture and catalyst, the catalyst isolated returns to reactor and is continuing with, and supplements the catalyst of loss amount；Product separation is carried out to reactant mixture, i.e. clear liquid, para aminotenzaldehyde is obtained. |
