摘要:
The present invention provides a novel lubricating composition comprising polybutylene glycol having a cap of a fluorinated alkyl group on at least one end thereof. The composition has a molecular weight between about 300 and about 4,000, and a viscosity of about 5 to about 150 centistokes at 37.degree. C. The composition is miscible in combination with refrigerant.As such, the present invention provides a composition for use in compression refrigeration and air-conditioning comprising: (a) a refrigerant selected from the group consisting of hydrofluorocarbon, hydrochlorofluorocarbon, fluorocarbon, and chlorofluorocarbon; and (b) a sufficient amount to provide lubrication of at least one polybutylene glycol having a cap of a fluorinated alkyl group on at least one end thereof.

摘要:
Azeotrope-like compositions comprising trichlorotrifluoroethane, ethanol, nitromethane and 2-methylpentane or a mixture of hexanes which are stable and have utility as degreasing agents and as solvents in a variety of industrial cleaning applications.
摘要:
Provided are azeotropic and azeotrope-like compositions of trans-1,3,3,3-tetrafluoropropene (HFO-1234ze(E)) and water. Such azeotropic and azeotrope-like compositions are useful in isolating trans-1,3,3,3-tetrafluoropropene from impurities during production. Azeotropes of the instant invention are similarly useful in final compositions or for the manufacture of final compositions, such as blowing agent, propellants, refrigerants, diluents for gaseous sterilization and the like.
