A STUDY OF ADDITIVES SYNTHESIZED FROM DERIVATIVES OF NAPHTHENIC HYDROCARBONS

Abstract : In order to develop antioxidant motor-oil additives whose composition includes phosphorus and sulfur, monochlorides of cyclohexyl- and methylcyclohexylphosphorous acids were prepared. The chlorides obtained were subjected to condensation reactions with various alkyl phenols (C3-C10) and sulfide-disulfide alkyl phenols. The effect of the synthesized compounds on the performance characteristics of D-11 oil was investigated.
