YieldReaction ConditionsOperation in experiment
71.5%; 21.4% With hydrogen fluoride; at 5 - 120℃; under 15001.5 Torr; for 2h;Product distribution / selectivity; The mixture of benzotrichlorides from Example 1a is passed directly to the fluorination reactor, which consists of an AISI 316 steel autoclave equipped with a stirrer and connected via a valve for pressure control to the gaseous hydrogen chloride absorption system. Once the mixture of benzotrichlorides has been charged into the autoclave, it is cooled to 5 C and 25.5 mmol (510 g) of anhydrous hydrofluoric acid are added. While the mixture is subjected to vigorous stirring in such a manner as to permit the two phases to react, it is heated until it reaches a final temperature of 120 C which is maintained for 2 hours. The pressure within the autoclave is maintained at 20 bar by means of a control valve and the stream of gaseous HCl leaving the autoclave (15 mol, 547.5 g) is absorbed in water to produce 32% HCl for commercial use. When the production of gaseous HCl has ceased and the pressure remains constant, the reaction is complete. The temperature is lowered, stirring is stopped and the phases are separated in appropriate apparatus. The resultant organic phase (5 mol, 1133.5 g) is vacuum distilled to obtain 3.58 mol (768 g) of 3,4-dichlorobenzotrifluoride of a purity of 99.5% (yield 71.5%) and 1.07 mol (268 g) of 3,4,5-trichlorobenzotrifluoride of a purity of 99% (yield 21.4%). The remaining 98 g consist of 2,4,5-trichlorobenzotrifluoride and 2,3,4,5-tetrachlorobenzotrifluoride and remain as heavy bottoms products
