    摘要: A process for catalytic direct oxidation of hydrocarbons, particularly lower alkanes and single ring aromatics, to acids by dioxygen under mild temperature conditions using specified metal or metal salt catalysts. Turnovers in excess of 1000 for acetic acid formation from ethane and in excess of 100 for formic acid formation from methane have been obtained at reaction temperatures below about 100.degree. C. using palladium catalyst. A coreductant of carbon monoxide in an aqueous system is preferred.

    摘要: Polymer blends having improved electromechanical responses and mechanical properties for use in electromechanical application are disclosed. In particular, polymer blend including at least one electrostrictive terpolymer, e.g., poly(vinylidene fluoride-trifluoroethylene-chlorofluoroethylene) (P(VDF-TrFE-CFE)) or a derivative thereof, and at least one fluoropolymer, e.g., PVDF or derivative thereof such as PVD-TrFE are disclosed. The polymer blends advantageously have a transverse strain, i.e., a strain perpendicular to the applied electric field direction, that is about 1.5% or higher (as measured at 100 MV/m) while also having an elastic modulus of no less than about 400 MPa (as measured at 30° C. and 1 Hz by dynamic mechanical analyzer).

    摘要: A process for direct oxidative carbonylation of lower alkanes to acids having one greater carbon atom. The process uses a metal salt catalyst promoted by halide ions and/or a metal with oxygen as the oxidant in an aqueous medium. The process is especially effective for conversion of methane to acetic acid.
