실험 절차

0.5 g of potassium chloride and 10 g of difluoromethoxybenzene were placed in 100 ml of 1,3-bistrifluoromethylbenzene and chlorine was then introduced at 100° C. under UV irradiation. A further 20 g of difluoromethoxybenzene were metered in over a period of 1 hour. When the chlorine uptake had ended, the mixture was purged with nitrogen and then distilled to give 35.5 g of chlorodifluoromethoxybenzene (boiling point: 144° C., refractive index nD20 : 1.4479).
