Procedure

248 g of the 1,2-bistrifluoromethoxybenzene thus obtained were allowed to drop at 0° C. in the course of 2 hours into 250 g of a mixture of 33% by weight of nitric acid and 67% by weight of sulphuric acid. The mixture was subsequently stirred at 0° C. for 5 hours, then added to ice water, and the organic phase was separated off and distilled. 284 g of 99% strength 3,4-bistrifluoromethoxynitrobenzene were obtained.
