反応手順

10 g (51.5 m mols) terephtalic acid dimethylester was dissolved in 100 g methane-sulfonic acid under agitation at room temperature. The solution was cooled to 15° C., whereupon 15 g (0.309 mol) 70% hydrogen peroxide was added by drops under agitation. The temperature was increased and kept at 50° C. for 2 hours. The product was cooled to 0°-10° C., whereupon the solid particles were filtered off, washed with 4×30 ml ice-water and dried in a desiccator until constant weight.
