FIELD: chemistry.
SUBSTANCE: emulsifying composition suitable for mixing with oil in order to obtain lubricating materials contains mixture, which includes: A) product of joined sulfonation of mixture: i) petroleum oil, ii) dialkylbenzol with unbranched chain, and, probably, iii) monoalkylbenzol with unbranched chain, and B) low-soluble synthetic sulphonate of unbranched monoalkylbenzol with molecular weight of about 520. Lubricating-cooling composition contains petroleum oil and said emulsifying composition.
EFFECT: stabilisation of emulsifying properties, improvement of anti-corrosion properties.
