FIELD: chemistry.
SUBSTANCE: mixture of monoalkyldiphenylphosphates and dialkylmonophenylphosphates is obtained from reacting phosphorous oxychloride with phenol, after which dichloromonophenylphosphate and monochlorodiphenylphosphate are reacted with aliphatic alcohol in the presence of catalyst - Lewis acid in the absence of a solvent at temperature 60-200°C and pressure from 0.001 to 1.1 bar abs.
EFFECT: design of a new method of producing alkylphenylphosphates and their mixtures, suitable for use plasticisers, lubricants and fireproofing compositions.
