| titleOfInvention | A kind of preparation method of 5-amino-1,2,3-benzenetricarboxylic acid |
| abstract | The invention belongs to the technical field of fine chemicals, in particular to a method for preparing 5-amino-1,2,3-tristricarboxylic acid, comprising the steps of: dissolving 1,2,3-mellitic acid in a nitric acid environment; The nitric acid solution containing 1,2,3- trimellitic acid is reacted with sulfuric acid; 5-nitro-1,2,3- trimellitic acid is obtained; 5-nitro-1,2,3- trimellitic acid is obtained Dissolve in methanol; react the obtained mixed solution with hydrogen; filter, concentrate, recrystallize, and refine to obtain 5-amino-1,2,3-benzenetricarboxylic acid; 5-amino-1,2,3-benzenetricarboxylic acid of the present invention The preparation method of triformic acid, because the microchannel reactor has the characteristics of low liquid holdup, high heat exchange efficiency, good mass transfer efficiency, etc., it can effectively solve the mass transfer, heat exchange, safety, etc. in the nitrification reaction and catalytic hydrogenation reaction. The problem is that the safety is greatly improved. The two-step reaction of nitration reaction and nitro reductive amination can be continuously synthesized, and the reaction can be started and stopped at any time without amplification effect, which provides an effective method for industrial safety production. |
