METHOD FOR PRODUCTION OF O-(2-ETHYL-N-HEXYL)-O-(3,4,5-TRITHIATRICYCLO[5.2.1.0]-DEZ-8-YL-METHYL)-DITHIOPHOSPHORIC 1-(N,N-DIMETHYLAMINOMETHYL)-1,2,4-TRIAZOLE SALT AS LUBRICANT OIL ADDITIVE Russian patent published in 2005 - IPC

Abstract RU 2249596 C1

FIELD: synthesis of lubricant oil additives.

SUBSTANCE: method for production of O-(2-ethyl-n-hexil)-O-3,4,5-trithiatricyclo[5.2.1.0^2,6]-dez-8-yl-methyl)-dithiophosphoric acid 1-(N,N-dimethylaminomethyl)-1,2,4-triazole salt of general formula

is disclosed. 1-(N,N-dimethylaminomethyl)-1,2,4-triazole is brought into reaction with equimolar amount of O-(2-ethyl-n-hexyl)-O-3,4,5-trithiatricyclo[5.2.1.0^2,6]-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.
