YieldReaction ConditionsOperation in experiment
88% With sodium hydroxide; In water monomer; at 105 - 140℃; for 5h; Second step reaction: A total of 600 g of 20% sodium hydroxide solution was prepared, the temperature was raised to 105 C and 189.8 g of 3,5-dichloro-2,4,6-trifluorobenzonitrile was added dropwise while stirring. Until the raw materials are completely reacted. The temperature was raised to 140 C and then decarboxylated for 5 hours until the content of 3,5-dichloro-2,4,6-trifluorobenzoic acid was less than or equal to 0.5%, and the reaction was completed. After cooling, the layers were separated, and the lower organic layer was the final product, 1,3-dichloro-2,4,6-trifluorobenzene. A total of 148.5 g of a colorless liquid was obtained, with a yield of 88%.
