When the molar ratio of TBA to HQ was 1.2:1, using 3mol% of PPFSI as catalyst in 1,2-dichloroethane at 130°C for 5h, the maximum of selectivity (85.9%) of 2-TBHQ was obtained while the conversion of HQ was 76.7%. Compared with other solid acid catalysts PPFSI was found to be a very effective and reusable catalyst for alkylation of hydroquinone with tert-butanol.
