The present invention relates to a process to prepare dialkyl monophenyl phosphate, monoalkyl diphenyl phosphate or mixtures thereof wherein dichloromonophenyl phosphate and/or monochlorodiphenyl phosphate is reacted with an aliphatic alcohol in the presence of a Lewis acid catalyst and in the absence of solvent at a temperature of 40 to 200°C and a pressure of 0 to 1 bar. The present invention further relates to mixtures of monoalkyl diphenyl phosphates and dialkyl monophenyl phosphates obtainable from the above process and the use of such mixtures as a plasticiser and/or a flame retardant.
