Preparing thiophosphoric acid triamide, useful as additive in urea containing mineral, organic-mineral fertilizers, comprises reacting thiophosphoric acid trichloride with amine and ammonia in an inert solvent in the presence of a base

摘要

Preparing thiophosphoric acid triamide (I) comprises reacting thiophosphoric acid trichloride with at least one amine and ammonia in an inert solvent in the presence of at least one base, which on reaction with hydrogen chloride forms a hydrochloride salt with a melting point of less than 100[deg]C.
