On January 23, 1974, Bowden, Roy D.; Seaton, Thomas published a patent.Safety of 4-Chloro-2,6-difluoropyridine The title of the patent was Chlorofluoropyridines. And the patent contained the following:
Chlorofluoropyridines were prepared by vaporization of CCl4, CCl3F, or F2ClCCFCl2 solutions of fluoropyridines at 290-350° with solvent and reactant feed rates 0.18-0.6 and 0.025-0.125 mole/hr, resp., and contacting the vapor with Cl feed rate 0.5-1.10 mole/hr at 335-695° for 9.0-25.0 sec. Thus, CCl4 solution of 2-fluoropyridine, feed rates 0.3 and 0.025 mole/hr, resp., was vaporized at 290° and the vapor contacted with Cl feed rate 0.52 mole/hr at 375° for 23.5 sec to give 70% 6-chloro-2-fluoropyridine and traces of 5,6-, 4,6-, and 3,6-dichloro-2-fluoropyridines. The experimental process involved the reaction of 4-Chloro-2,6-difluoropyridine(cas: 34968-33-7).Safety of 4-Chloro-2,6-difluoropyridine
