Description

General description

4-tert-Butyl-o-xylene (1,2-dimethyl-4-tert-Butylbenzene, DMTBB) is a dimethylalkylbenzene. It has been synthesized by reacting o-xylene with tert-butyl alcohol over zeolite based catalytic system.

Application

4-tert-Butyl-o-xylene may be used as a starting material in the synthesis of 1,2-bis(bromomethyl )-4-tert-butylbenzene. It may also be used as a solvent in the synthesis of 2,7-di-tert-butylcarbazole, via ring closure of 4,4′-di-tert-butyl-2,2′-diaminobiphenyl in the presence of Nafion-H.
