Title
Poly(styrene sulfonic acid)–grafted carbon nanotube as a stable protonic acid catalyst
Abstract

Poly(styrene sulfonic acid)–grafted carbon nanotube was prepared and used as a solid acid catalyst in the alkylation of hydroquinone with tert-butanol. The material exhibits high activity as well as good stability as compared with other carbon-based solid acids. 73.3% of conversion and 53.7% of 2-TBHQ yield can be reached at 150 °C.
