Reaction Steps
Finally, 170 ml/h of hydrogen fluoride (measured as liquid) and 148 g/h of 2-chloro-2,3,3-trifluorobenzodioxane were passed over the catalyst at 300° C. In the course of 7 hours, 930 g of 2,2,3,3-tetrafluorobenzodioxane were obtained. This corresponds to a degree of fluorination of 97%.
