摘要： This invention relates to a process for the removal of dissolved species from aqueous solutions, which comprises contacting said aqueous solution with an emulsion, said emulsion comprising an exterior phase which is characterized as being immiscible with said aqueous solution and yet permeable to said dissolved species, and an interior phase which contains a reactant capable of converting said dissolved species to a non-permeable form. The dissolved species permeate the exterior phase, into the interior phase where they are converted into nonpermeable forms and thus retained in the interior phase of said emulsion. The aqueous solution, depleted in said dissolved species, is separated from said emulsion and the emulsion cycled for reuse. In one preferred embodiment said dissolved species are ions, and an ion exchange compound is incorporated in the exterior phase of the emulsion, to promote the permeation of said ions through the exterior phase.

摘要： Lubricating oil fractions are dewaxed by contacting them with successive increments of cold solvent at a plurality of points along a vertical tower while maintaining a zone of intense agitation at each point of solvent injection so that substantially instantaneous mixing occurs at each point, continuing the chilling by means of cold solvent injection until a temperature greater than the filtering temperature but less than about 35*F. above the filtering temperature is reached and completing the cooling of the oil to the separation temperature in a scraped-surface cooler.

摘要： UNSATURATED ALCOHOLS AND ETHERS ARE PREPARED THROUGH THE REACTION OF C4 TO C6 ALIPHATIC CONJUGATED DIOLEFINS WITH WATER, A LOWER ALKANOL OR MIXTURES THEREOF IN THE PRESENCE OF A ZERO VALENT PALLADIUM BASED CATALYST SYSTEM. THE PREFERRED CATALYST IS TETRAKIS(TRIBENZYLPHOSPHINE) PALLADIUM TETRAKIS(DIPHENYLALKLPHOSPHINE)PALLADIUM OR TETRAKIS(TRIPHENYLPHOSPHINE)PALLADIUM ALONE OR IN COMBINATION WITH A BASIC MATERIAL SUCH AS A QUATERNARY AMMONIUM HYDROXIDE. WHERE ONE OF THE COREACTANTS IS WATER, THE REACTION IS CONDUCTED IN THE PRESENCE OF A SOLVENT. THE UNSATURATED ALCOHOL AND ETHER PRODUCTS CAN BE CATALYTICALLY HYDROGENATED TO PLASTICIZER ALCOHOLS AND ETHER SOLVENT MEDIA.

摘要： A HIGHLY TEAR RESISTANT NONWOVEN MAT OF THERMOPLASTIC POLYMER FIBERS IS MADE IN A MELT-BLOWING PROCESS IN WHICH A MOLTEN POLYMERIC RESIN IS EXTRUDED THROUGH A ROW OF DIE OPENINGS INTO A STREAM OF HOT GAS WHICH ATTENUATES THE RESIN INTO FIBERS HAVING DIAMETERS BETWEEN ABOUT 10-40 MICRONS. THE FIBERS ARE COLLECTED ON A CONTINUOUSLY MOVING SURFACE POSITIONED FROM ABOUT 10 TO ABOUT 30 INCHES FROM THE DIE OPENINGS.
