Carbon fluoride - by reacting carbon black with fluorine

摘要

The carbon fluoride is prepd. by heating a carbon black at temp. above 700 degrees C in the absence of air and subjecting to the action of fluorine at 500-600 degrees C. Fluorination is effected at atmospheric or superatmospheric pressure. Carbon black can be more easily fluorinated than graphite, and more uniformly fluorinated prodts. are obtd.
