  • Publication number: 20130219635
    Abstract: In a method of dyeing and finishing cotton fibers, emulsion copolymer treated cotton fibers are prepared by contacting the fibers with an emulsion copolymer and curing the copolymer under conditions to chemically anchor the emulsion copolymer to the cotton and thereby form copolymer-treated cotton fibers. The copolymer-treated cotton fibers are then contacted with a dye material under conditions sufficient to affix at least a portion of the dye material to the copolymer component of the copolymer-treated cotton fibers and produce dyed cotton fibers. Thereafter, the dyed cotton fibers are treated with a surfactant-stabilized aqueous acrylic polymer dispersion to give the fibers a worn or vintage character.

  • Publication number: 20130158297
    Abstract: Disclosed herein are processes for alcohol production by hydrogenating acetic acid to obtain a mixture of ethanol and acetic acid, esterifying the mixture to produce an esterification product and reducing the esterification product. The mixture may provide a sufficient amount of ethanol and acetic acid for esterification and reduces the need for additional acetic acid and/or ethanol. This may reduce the recycle of ethanol in the hydrogenolysis process and improve ethanol productivity.

  • Publication number: 20130158302
    Abstract: Disclosed herein are processes for alcohol production by reducing ethyl acetate produced by hydrogenating acetic acid in the presence of a suitable catalyst. The product of the acetic acid hydrogenation is fed directly to a decanter to separate the hydrogenation product into an aqueous phase comprising water and ethanol and an organic phase comprising ethyl acetate. The organic phase is reduced with hydrogen in the presence of a catalyst to obtain a crude reaction mixture comprising the alcohol, in particular ethanol, which may be separated from the crude reaction mixture. Thus, ethanol may be produced from acetic acid through an ethyl acetate intermediate without an esterification step. This may reduce the recycle of ethanol in the hydrogenolysis process and improve ethanol productivity.

  • Publication number: 20130102809
    Abstract: A carbonylation process for making acetic acid uses a metallic co-catalyst composition effective as a rhodium stabilizer and rate promoter at molar ratios of metal/rhodium of from about 0.5 to 30. A preferred process includes: (a) reacting methanol with a carbon monoxide feedstock in a rhodium-based catalytic reaction mixture having: (i) a rhodium catalyst metal, (ii) methyl iodide maintained from about 1 to 20 weight percent, (iii) a lithium iodide co-catalyst, (iv) a metallic co-catalyst composition, (v) water maintained from 0.1 weight percent to less than 8 weight percent, (vi) methyl acetate maintained from about 0.5 to about 30 weight percent, and (vii) acetic acid; (b) flashing crude acetic acid from the reaction mixture; and (c) purifying the crude acetic acid. This process achieves stability and a STY greater than 10 mol/L/hr, with substantially less than a theoretically equivalent inorganic iodide content corresponding to the metallic co-catalyst and lithium iodide.
