METHOD FOR PRODUCING SOLID TRIAZOLINEDIONE COMPOUND, SOLID TRIAZOLINEDIONE COMPOUND, AND METHOD FOR PRODUCING TRIAZOLINEDIONE COMPOUND

摘要

Provided are a method for separating a DAPTAD-containing triazolinedione compound in solid form from a reaction solution, a separated solid triazolinedione compound, and a novel method for producing a triazolinedione compound. A triazolinedione solution in which a DAPTAD-containing triazolinedione compound is dissolved is brought into contact with a C5-15 hydrocarbon-based poor solvent to obtain a solid triazolinedione compound. Also, a triazolinedione compound is oxidized using an oxidizing agent that does not produce acid as a byproduct to obtain a triazolinedione compound.
