  • Patent number: 9045385
    Abstract: A process is disclosed that includes brominating a C2, C3, C4, C5 or C6 alkane with elemental bromine to form a bromo-alkane. The bromo-alkane is reacted to form a C2, C3, C4, C5 or C6 alkene and HBr. The HBr is oxidized to form elemental bromine.
    Type: Grant

  • Patent number: 9017624
    Abstract: A method comprising: providing an alkyl halide stream; contacting at least some of the alkyl halides with a coupling catalyst to form a product stream comprising higher hydrocarbons and hydrogen halide; contacting the product stream with a solid reactant to remove at least a portion of the hydrogen halide from the product stream; and reacting the solid reactant with a source of oxygen to generate a corresponding halogen.

  • Patent number: 9018427
    Abstract: A reactive distillation method comprises introducing a feed stream to a reactive distillation column, contacting the feed stream with one or more catalysts in the reactive distillation column during a distillation, and removing one or more higher alcohols during the distillation from the reactive distillation column as a bottoms stream. The feed stream comprises one or more alpha hydrogen alcohols, and the feed stream reacts in the presence of the one or more catalysts to produce a reaction product comprising the one or more higher alcohols.

  • Patent number: 6605738
    Abstract: Crude butyl acrylate streams, e.g., from the reaction of butanol and acrylic acid, are refined using a splitter distillation column to yield a butyl acrylate- and heavies-containing bottoms fraction and an overhead fraction containing dibutyl ether, butyl acetate, butanol and butyl acrylate. The bottoms fraction is then subjected to separation, e.g., by distillation, to separate heavies from the bottoms fractions and to recover butyl acrylate.
