  • Monophospha-S-triazines of improved hydrolytic and thermal oxidative stability
    Patent number: 5326910
    Abstract: Hydrolytically and thermooxidatively stable monophospha-s-triazines prepared by reaction of octafluoroisobutylene epoxide with an acid fluoride followed by transformation of the resultant product into an amide, then into a nitrile, reacting the nitrile with ammonia and reacting the imidoylamidine resulting from the previous steps with di-aryltrihalophosphorane to produce mono-phospha-s-triazines that are useful as antioxidant - anticorrosion agents for perfluoroalkylether fluids are disclosed.

  • Trisilahydrocarbon lubricants
    Patent number: 4788312
    Abstract: Trisilahydrocarbon synthetic lubricant base stocks are prepared by the reaction of dienes containing four to sixteen carbon atoms with dihalosilanes, followed by further reaction of the bis(alkenyl)dihalosilane intermediates with trihalosilanes or trialkylsilanes, followed by substitution of the halogen atoms in the second intermediates by organometallic compounds or by hydridometallic compounds plus olefins.
