FIELD: chemistry. n SUBSTANCE: use for all-season transmission operation of front-wheel drive cars. Substance: oil contains, mass %: sulphur-containing additive - 3.5, zinc dialkyl dithiophosphate - 0.3, polymethacrylate - 1.9, silicone additive - 0.004, petroleum oil up to 100. Sulphur-containing additive is resultant from reaction of α- olefins of C 16 -C 18 fractions with sulphur with catalyst being reaction product of diisobutyl phosphoric acid and butyl methacrylate taken in equimolar amounts at temperature 70-75°C. n EFFECT: improvement of oil low-temperature properties. n 1 tbl |
