Abstract:

   The goal is to utilize direct fluorination technology to produce perfluoroalkyletherfluids and lubricants.  The direct fluorination process involves the selection of
a hydrocarbon with the proper structure which is converted to fluorocarbon by a controlled
reaction with elemental fluorine.  Since the starting material is a hydrocarbon,
numerous structures can be made due to the wide variety of monomers and synthetic
techniques available.  In contrast, the synthesis of fluorocarbon polymers from fluorocarbon
monomers is costly and the types of reactions that can be carried out are extremely
limited.  The perfluoro-
alkylethers produced will have a variety of uses in environments where extreme stability,
very low vapor pressure, low acute toxicity, high lubricity and very low pour points
are required.  Nowhere is this demand so evident as in the aeronautical and space
industries.
