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
