    摘要： A bisphenol monoester represented by the formula (I): ##STR1## wherein R.sup.1 is hydrogen or alkyl, R.sup.2 and R.sup.3 are each alkyl, and R.sup.4 is alkyl, alkenyl or phenyl, is produced by continuous two step reactions in which an aldehyde R.sup.1 -CHO and 2,4-dialkylphenol are subjected to a condensation reaction in a C.sub.6 -C.sub.10 aliphatic or C.sub.6 -C.sub.12 aromatic hydrocarbon solvent, and then a resulting bisphenol compound dissolved in the solvent is subjected to an esterification with a carboxylic acid R.sup.4 --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 C.sub.6 -C.sub.12 aromatic hydrocarbon solvent and a C.sub.1 -C.sub.8 alcohol or C.sub.2 -C.sub.3 aliphatic nitrile solvent.
