Abstract: Disclosed are methods of producing a supported organic catalyst system comprising the steps of: (a) providing an organic catalyst solution comprising an organic catalyst dissolved in a supercritical-like solvent; (b) contacting a support material with the organic catalyst solution; and (c) removing substantially all of the supercritical-like solvent from the organic catalyst and the support material.

Abstract: A process for removing a chlorinated methane impurity from a stream comprising a halogenated compound other than the chlorinated methane impurity, the process comprising contacting the stream with a polymer adsorbent to produce a purified product stream, the polymer adsorbent having a pore size distribution characterized by a higher cumulative porosity as a function of the log of pore diameter than that of activated carbon.

Abstract: Disclosed are methods of cleaning articles of manufacture using hydrofluorocarbon and hydrochlorofluorocarbon fluids. The methods comprise generally the steps of (a) providing a hydrofluorocarbon and/or hydrochlorofluorocarbon fluid in liquid or supercritical state; (b) contacting an article of manufacture with said fluid; and (c) removing substantially all of said fluid from said article of manufacture.

Abstract: Provided are azeotropic and azeotrope-like mixtures of 1,1,1,3,3-pentafluoropropane (HFC-245fa) and 1-chloro-1,1,3,3,3-pentafluoropropane (HCFC-235fa) that are useful as intermediates in the production of HFC-245fa. A process for separating HFC-245fa and HCFC-235fa is also provided. HFC-245fa is useful as a nontoxic, zero ozone depleting fluorocarbon useful as solvents, blowing agents, refrigerants, cleaning agents, aerosol propellants, heat transfer media, gaseous dielectrics, fire extinguishing compositions and power cycle working fluids.

Abstract: Disclosed are methods of producing supported organic catalyst systems which find particular use in polymerization reactions. The methods comprise generally, the steps of (a) providing an organic catalyst solution comprising an organic catalyst dissolved in a solvent; (b) contacting the organic catalyst solution with a solid support material; and (c) removing the solvent from the support material by using one or more supercritical-like solvents.

Abstract: A method for removing unsaturated impurities from 1,1-difluoroethane by intimately contacting the impure 1,1-difluoroethane with sulfuric acid. This process is especially useful for removing one or more unsaturated halocarbons having two carbon atoms such as vinyl chloride, vinyl fluoride and blends thereof from the 1,1-difluoroethane.
