Abstract

PURPOSE: To prevent the discoloration of the titled compound with time, and to obtain the titled compound having high commercial value, by adding a specific amount of a phosphaphenanthrene compound such as triphenyl phosphite, to crude o-phenylphenol before or after purification.
CONSTITUTION: Before or after the purification of a reaction mixture containing o-phenylphenol obtained by the dehydrogenation, etc. of cyclohexenyl cyclohexanone or o-cyclohexylphenol, 0.01W2.0wt%, based on o-phenylphenol, of a phosphite of formulas IWIII (R1WR3 are alkyl, aryl or alkylaryl) and/or a phosphaphenanthrene compound of formula IV (R1'WR1' are H or alkyl) is added to the reaction mixture. It is effective to melt the o-phenylphenol at 60°C before the addition of the above compound.
