  • Process for making 2,6-difluoro pyridine
    Patent number: 4071521
    Abstract: It has been found that practical rates of formation of 2,6-difluoropyridine from 2,6-dichloropyridine and KF can be attained without resort to catalysts, high temperatures or large excesses of KF, if:A. dimethyl sulfoxide (DMSO) is employed as the reaction medium,B. the reaction mixture contains less than 0.015 grams of HF and 0.5 grams of K.sub.2 CO.sub.3 or KHCO.sub.3 per 100 grams of KF and less than 0.5 grams of water per 100 grams of DMSO,c. the difluoropyridine is distilled out as formed, andD. the reaction mixture is intensely stirred and kept at a temperature of 175.degree.-192.degree. C.
