YieldReaction ConditionsOperation in experiment
With potassium fluoride; 3-Chloro-2,4-difluoro-benzotrifluoride 3,700 g of potassium fluoride are initially introduced into 10,000 ml of tetramethylene sulphone in a stirred apparatus with exclusion of moisture, and 500 ml of tetramethylene sulphone are distilled off under a pressure of 16 mbar. 3,965 g of 2,3,4-trichlorobenzotrifluoride are then metered in and the mixture is heated to 230 C. The product formed is taken off via a column with a reflux divider. After three hours, a slight vacuum is applied and the mixture is subjected to incipient distillation up to the boiling point of tetramethylene sulphone. The coarse distillate (3,390 g) is subjected to fine distillation. The first runnings of 396 g comprise mainly 2,3,4-trifluoro-benzotrifluoride (boiling point 92-142 C.; the main runnings (3,051 g) have a boiling point of 142-143 C. and comprise 3-chloro-2,4-difluorobenzotrifluoride to the extent of 97.6%.
