摘要:
The present invention relates to a process of producing .alpha., .alpha., .alpha., .alpha.', .alpha.', .alpha.'-hexakisaryl-1,3- and -1,4-dimethyl benzenes by reacting .alpha., .alpha., .alpha.', .alpha.'-tetrakisaryl-1,3 or -1,4-bis-(chloromethyl)- or -bis-(hydroxymethyl)- benzenes with 2 to 30 times the molar quantity (based on the tetrakis benzene) of phenol or a substituted phenol.
