Procedure
A 34 cubic centimeter Inconel™ reactor tube, equipped with a ceramic fiber heater, was packed with Takeda™ brand activated carbon. The activated carbon and reactor were purged with nitrogen between 150° C. and 200° C. The reactor was connected to tubing providing chlorine and the hydrofluorocarbon heptafluoropropane (HFC-227, containing 839 ppm 227ca and the remainder HFC-227ea). The flow of the chlorine and HFC-227 were controlled with gas flowmeters. Tables 1 and 2 below indicate the reaction parameters as well as the results. Fluoromonomer precursor chloroheptafluoropropane (CFC-217) exiting the reactor was first passed through a 10% (wt./wt.) KOH solution and then dried over CaSO4 before being captured for subsequent gas chromatography analysis.
