SYNTHESIS OF NEW HIGH PERFORMANCE LUBRICANTS AND SOLID LUBRICANTS
Technical Progress Report
We have been making very substantial progress during the first year of
our Department of Energy grant number DE-FG05-91ER12119 on many fronts. We
have started to make a number of classes of new perfluoropolyethers both in
the solid lubricant area and liquid lubricant area.
One of the steps that we have taken that we think is most significant is
that we have prepared some chlorofluoroethers for testing as additives for
normal petroleum and polyalphaolefin lubricants which are so widely used in
the United States. We have recently made (see pages 53 and 54 of our original
proposal) arrangements with Shell Development Company located in Houston,
Texas to test these as motor oil additives and polyalphaolefin additive
packages. Dr. Larry Olejnik, Manager of Fuels and Lubricants at Shell
Development company's Westhollow Research Center in Houston is in charge of
this testing. We are very anxious in the future to receive reports that
confirm our feelings that these have the potential to become superb energy
saving additives. As stated in the proposal, these perfluoropolyethers are
not soluble in hydrocarbons. On the other hand, these chlorofluoropolyethers
are soluble in substantial amounts in simple hydrocarbons. These are uniquely
capable of being additives that flow with the motor oil or the
polyalphaolefin. Teflon (polytetrafluoroethylene) which has been used as an
additive in motor oils is not soluble in hydrocarbons and is simply burnished
(coated) on piston and cylinder walls. In spite of the fact that
fluorocarbons are extraordinarily stable, no oil or fluorocarbon is stable for
long periods of time at the temperatures at which internal combustion engines
