Production of bisphenol monoester

A bisphenol monoester represented by the formula (I): STR1 wherein R1 is hydrogen or alkyl, R2 and R3 are each alkyl, and R4 is alkyl, alkenyl or phenyl, is produced by continuous two step reactions in which an aldehyde R1 -CHO and 2,4-dialkylphenol are subjected to a condensation reaction in a C6 -C10 aliphatic or C6 -C12 aromatic hydrocarbon solvent, and then a resulting bisphenol compound dissolved in the solvent is subjected to an esterification with a carboxylic acid R4 --COOH or its derivative. Prior to the esterification, the organic layer containing the bisphenol compound is subjected to a dehydration treatment, thereby enabling the two steps to proceed continuously without isolating the intermediate bisphenol compound. A purification process for the bisphenol monoester of the formula (I) is also disclosed in which the monoester is purified from a mixed solvent comprising a C6 -C12 aromatic hydrocarbon solvent and a C1 -C8 alcohol or C2 -C3 aliphatic nitrile solvent.
