FIELD: synthesis of lubricant oil additives.
SUBSTANCE: method for production of O-(2-ethyl-n-hexil)-O-3,4,5-trithiatricyclo
-dez-8-yl-methyl)-dithiophosphoric acid 1-(N,N-dimethylaminomethyl)-benzotriazole salt of general formula 
2 is disclosed. 1-(N,N-dimethylaminomethyl)-benzotriazole is brought into reaction with equimolar amount of O-(2-ethyl-n-hexyl)-O-3,4,5-trithiatricyclo
-dez-8-yl-methyl)-dithiophosphoric acid in toluene medium at 80-100°C for 2-4 h.
EFFECT: ash-free antiscoring lubricant oil additive operating under high pressure.
