Purified para-cumylphenol

摘要

Method of preparing para-cumylphenol including reacting an excess of phenol with alpha-methylstyrene by the slow addition of alpha-methylstyrene to a 50% to 200% molar excess of phenol at a temperature from about 80 DEG C. to about 90 DEG C. in the presence of an acid catalyst and thereafter maintaining the temperature at about 95 DEG to about 100 DEG C. to obtain a crude cumylphenol reaction product containing acid derived from the catalyst, and distilling the reaction product in the presence of an amount of base sufficient to neutralize the acid therein.
