Reaction Steps

According to another embodiment of the present invention, a 34 cubic centimeter Inconel™ reactor tube is equipped with a ceramic fiber heater. The reactor is purged with nitrogen between 150° C. and 200° C. The reactor is connected to tubing providing chlorine and the hydrofluorocarbon heptafluoropropane (HFC-227). The flow of the chlorine and HFC-227 is controlled with gas flowmeters. Table 3 below indicates the suggested reaction parameters as well as the expected results. Fluoromonomer precursor chloroheptafluoropropane (CFC-217) exiting the reactor is first passed through a 10% (wt./wt.) KOH solution and then dried over CaSO4, before being captured for subsequent gas chromatography analysis.
