A PROCESS FOR THE PRODUCTION OF .alpha., .alpha., .alpha., .alpha.', .alpha.', .alpha.'-HEXAKISARYL- 1,3- AND -1,4-DIMETHYL BENZENES Abstract of the Disclosure The present invention relates to a process of pro- ducing .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. The present invention also relates to a process for the production of the bis-chlorocarbonic acid esters of .alpha., .alpha., .alpha.', .alpha.', .alpha.'- hexakisaryl-1,3- and -1,4-dimethyl benzenes by reacting .alpha., .alpha., .alpha., .alpha.', .alpha.', .alpha.'-hexakisaryl-1,3- or -1,4-dimethyl benzene with 2 to 10 times the mo.lar quantity of phosgene. ~The products produced according to the instant invention have been found to be valuable intermediates, for example, for the production of high molecular weight aromatic poly- carbonates.
