摘要： Low-ethanol wines and other alcoholic beverages are produced by treating ordinary alcoholic beverages with novel membrane extraction methods. Semipermeable membranes and extraction fluids comprised either of a non-toxic, water-immiscible organic solvent or an aqueous solution of a low-molecular-weight but membrane-impermeable solute are used under mild conditions to selectively extract ethanol from alcoholic beverages, while leaving substantially intact the complement of other organic constituents that contribute to the color, aroma, and taste of the beverage. The methods disclosed may be adapted to continuous processing of alcohol-containing beverages, in which an ethanol-rich product is continuously recovered from the organic or aqueous extraction fluid and the latter is continuously regenerated and subsequently recycled to the membrane extraction unit.

摘要： Novel method for conducting phase transfer catalysis in a multiphase reaction system wherein the different phases are separated by a membrane permeable to the phase transfer catalyst and its various reaction complexes. The invention also relates to membranes and a membrane-containing apparatus useful in carrying out phase transfer catalysis.

摘要： Apparatus for catalysis in multiphase reaction systems in which catalysts are confined within various membranes without the use of covalent coupling. Confinement of the catalysts is achieved by a combination of a small-pore skin on one side of the membrane and the use of a solvent in which the catalysts are not appreciably soluble on the other. Methods are also provided for the preparation of such apparatus and for their regeneration by incorporation of fresh catalyst.
