    摘要: Soil fumigation compositions are provided herein that include methyl iodide, at least one fluorocarbon or hydrofluorocarbon, at least one surfactant, and water. The fumigant can be produced by combining the water and surfactant with an intial mixture that is an azeotropic or azeotrope-like mixture of methyl iodide and at least one fluorocarbon or hydrofluorocarbon. The fumigant compositions can be utilized in drip fumigation processes, and have increased volatility as compared to methyl iodide alone, which can reduce the risk of water contamination when utilizing methyl iodide as a fumigant.

    摘要: Disclosed is a process for making hexafluoro-2-butyne comprising the steps of: (a) providing a composition comprising CF3CX=CXCF3, where X = halogen; and (b) treating CF3CX=CXCF3 with a dehalogenation catalyst in the presence of a halogen acceptor compound Y, where Y is not hydrogen. The halogen acceptor compound Y is a material capable of being halogenated, preferably a compound having a multiple bond, such as an alkyne, alkene, allene, or carbon monoxide. Another suitable material capable of being halogenated is a cyclopropane. A catalyst effectively transfers halogen from CF3CX=CXCF3 to the halogen acceptor compound. Since Y is not hydrogen, the formation of CF3CX=CHCF3 is greatly reduced or eliminated.

    摘要: Disclosed is a process for the preparation of fluorine-containing olefins comprising contacting a chlorofluoroalkane with hydrogen in the presence of a catalyst at a temperature sufficient to cause replacement of the chlorine substituents of the chlorofluoroalkane with hydrogen to produce a fluorine-containing olefin. Also disclosed are catalyst compositions for the hydrodechlorination of chlorofluoroalkanes comprising copper metal deposited on a support, and comprising palladium deposited on calcium fluoride, poisoned with lead and reducing the in the presence or absence of a dehydrochlorination catalyst under conditions effective to form a product stream comprising cis-1,1,1,4,4,4-hexafluoro-2-butene (HFO-1336).
