SYNTHESIS OF MIXED FULL AND SEMIESTERS OF PHOSPHOROUS ACID AS ORGANIC MOTOR OIL ADDITIVES,

Abstract

The synthesis of mixed full and semiesters of phosphonic acid was effected using alkylphenols produced by the chemical industry. By condensation of acid chlorides of dicyclohexyl-, di-(2-methylcyclohexyl)-, 2-isopropyl-4-oxyphenyl- and 2,5-di-tert-butyl-4-oxyphenylphosphorous acid with an industrial alkylphenol or the condensation of acid chloride of di-(alkylphenyl)-phosphorous acid with diethylamine, the corresponding mixed full and semiesters of phosphorous acid are obtained. The yield of reaction products is 70-80%. Phosphorus content in the obtained phosphites varies from 5-7%. The obtained products are viscous substances of a bright yellow color, well soluble in organic solvents and mineral oils suitable for motor oil additives. (Author)
