Document Type and Number:
WIPO Patent Application WO/2005/108331
Kind Code:
A1
Abstract:
A process for preparing a halo-olefin to minimize one or more side reactions which form at least one impurity, said process comprising contacting a halogenated hydrocarbon with a metal dehalogenating agent dissolved in a solvent under conditions sufficient to dehalogenate said halogenated hydrocarbon to produce a product stream comprising said halo-olefin and at least one impurity, said metal dehalogenating agent having an average particle size within a range of average particle sizes, said impurity concentration of said product stream being essentially constant within said range and increasing significantly below said range.
