    摘要： A process for preparing superparamagnetic transition metal nanoparticles by introducing into a gas stream a hydrocarbon and a transition metal carboxyl wherein the transition metal carbonyl is introduced downstream from the hydrocarbon; wherein at the point of introduction of the hydrocarbon the gas stream is in the form of a plasma, and wherein at the point of introduction of the transition metal carbonyl the gas stream is at a temperature of at least 1000° C.; followed by quenching to form carbon-coated transition metal nanoparticles; and wherein the gas stream consists essentially of at least one inert gas and hydrogen.

    摘要： A process for the preparation of pentafluoroethane is disclosed which involves contacting a mixture comprising hydrogen fluoride and at least one starting material selected from haloethanes of the formula CX3CHX2 and haloethanes of the formula CX2═CX2, where each X is independently selected from the group consisting of F and Cl (provided that no more than four of X are F), with a fluorination catalyst in a reaction zone to produce a product mixture comprising HF, HCl, pentafluoroethane, underfluorinated halogenated hydrocarbon intermediates and less than 0.2 mole percent chloropentafluoroethane based on the total moles of halogenated hydrocarbons in the product mixture. The process is characterized by the fluorination catalyst comprising (i) a crystalline cobalt-substituted alpha-chromium oxide where from about 0.05 atom % to about 6 atom % of the chromium atoms in the alpha-chromium oxide lattice are replaced by trivalent cobalt (Co+3) and/or (ii) a fluorinated crystalline oxide of (i).
