Abstract
A micro-reaction system and a method for preparing 2-methyl-4-amino-5-aminomethyl pyrimidine. A Raney nickel catalyst is modified with formalin, and the modified Raney nickel catalyst is filled into a micro-channel reactor of the micro-reaction system. A substrate solution containing 2-methyl-4-amino-5-cyanopyrimidine and a base and hydrogen are transported to the micro-mixer and the micro-channel reactor in sequence for continuous catalytic hydrogenation to obtain 2-methyl-4-amino-5-aminomethyl pyrimidine.
