    摘要: A process for separating an unsaponifiable compound from a feed mixture including fatty and/or rosin acids. The process comprises: (a) forming an emulsion with the feed mixture, an organic solvent in which the feed mixture is soluble and an emulsifying liquid capable of forming an emulsion with the feedstock and organic solvent, the polarity index of the emulsifying liquid being at least 2.4 higher than the polarity index of the organic solvent; (b) effecting the formation of three phases from the emulsion, an organic solvent phase containing the major portion of the fatty or rosin acids, an emulsifying liquid phase and a semi-solid sludge phase containing the major portion of the unsaponifiable compound; and (c) separating the three phases.

    摘要: An adsorptive separation process for separating ethanol from a feed mixture comprising ethanol and water, which process comprises contacting the feed mixture with an adsorbent comprising esterified silica selectively adsorbing substantially all of the ethanol to be separated to the substantial exclusion of the water and thereafter recovering high purity ethanol. A desorption step may be used to desorb the adsorbed ethanol.

    摘要: An improved adsorbent comprising a crystalline aluminosilicate, method of manufacture of the adsorbent and improved process for separating a component from a feed mixture comprising an aqueous solution of a mixture of different components, such as a mixture of saccharides. In the process the mixture is contacted with the adsorbent, which selectively adsorbs a component from the feed mixture. The adsorbed component is then recovered by contacting the adsorbent with a desorbent material such as water to effect the desorption of the adsorbed component from the adsorbent. There is an undesirable tendency for the silicon constituent of the crystalline aluminosilicate to dissolve in the aqueous system. The improvement to the adsorbent and process comprises the incorporation of a binder material in the adsorbent comprising a water permeable organic polymer which substantially reduces the undesirable dissolution. The adsorbent is manufactured by mixing together powder of the crystalline aluminosilicate, powders of the organic polymer binder, and a liquid organic solvent, extruding the mixture into an extrudate and drying the extrudate.

    摘要: The present invention is for crosslinked membranes and in particular for crosslinked poly(ethylene oxide)-cellulose acetate-silsesquioxane (PEO-CA-Si) organic-inorganic hybrid membranes and their use in gas separation. These crosslinked PEO-CA-Si membranes were prepared by in-situ sol-gel co-condensation of crosslinkable PEO-organotrialkoxysilane and CA-organotrialkoxysilane polymers in the presence of acetic acid catalyst during the formation of membranes. The crosslinkable PEO- and CA-organotrialkoxysilane polymers were synthesized via the reaction between the hydroxyl groups on PEO (or on CA) and the isocyanate on organotrialkoxysilane to form urethane linkages under mild conditions. The crosslinked PEO-CA-Si membranes exhibited both increased selectivity of CO2/N2 and CO2 permeability as compared to a CA membrane, suggesting that these membranes are very promising for gas separations such as CO2/N2 separation.
