摘要：
Hydrazine sulfate having a relatively large particle diameter and a high purity is produced by hydrolysis of benzophenoneazines by sulfuric acid having a concentration of 75% by weight or less in an amount of 1.1 times by mole or more the stoichiometric amount in a very high conversion and a high yield with less operational loss.
