Abstract

1. Process for production of 2,4,5,6-tetra-amino-pyrimidine sulfate from 2,4,6-triamino-5-phenylazopyrimidine, characterized in that 2,4,6-triamino-5-phenylazopyrimidine, suspended in water or alcohol or dissolved in a diluted base, is hydrogenated in the presence of a catalyst containing palladium on carbon at 50 to 180 degrees C and an excess pressure of 0 to 60 bar and precipitated by the addition of the sulfuric acid.
