METHOD OF PREPARING AMINE SALTS OF DITHIOPHOSPHORIC ACID ESTERS Russian patent published in 1999 - IPC

FIELD: organoelemental compounds. SUBSTANCE: to prepare dithiophosphoric acid ester salts, elementary phosphorus interacts with elementary sulfur, aliphatic alcohol or mixture of aliphatic alcohols and phenol, or substituted phenol, or aliphatic alcohol-substituted phenol mixture at molar ratio 1:(2-2.2): (2-3):(1-1.2), respectively, at 50 to 140 C until conversion of phosphorus and sulfur is completed. Salts are obtained by using following amines: ammonia, primary, secondary, and tertiary aliphatic, aromatic, and heterocyclic amines, and carboxylic acid amides. EFFECT: simplified synthetic procedure. 4 cl, 1 tbl, 31 ex
