実験手順
A ten-fold excess, fifty (50) ml, of anhydrous ammonia gas were condensed into a four-neck flask fitted with an agitator, reflux condenser, dropping funnel, thermometer, and a drying tube (filled with solid KOH) which had been cooled in a dry ice/ethanol bath. The ammonia was condensed into the flask via the drying tube. With good agitation and cooling, 60 g of a reaction product (perfluoroheptanonitrile), made in accordance with the technique described in Example 4 for conversion of a perfluoroacid to a nitrile, having the structure C6F13CN was added slowly. After addition was completed, the temperature was allowed to slowly rise to ambient allowing the excess ammonia to evaporate. The resulting white solid product was air dried to yield 62.0 g of perfluoroheptanamide having the following formula (a yield of 98.5% with a m.p. at 75-76° C.).
