    摘要： A method for disposing of non-polar organic wastes including the steps of dissolving the organic waste in an organic solvent which is not environmentally objectionable, in combination with a suitable surfactant, mixing the resultant solution with a quantity of water to develop an emulsion in which the organic element is effectively dispersed in the water and thereafter mixing the emulsion with cement which, when allowed to solidify, encapsulates the organic waste within the solid cementitious mass. This solid mass is suitable for disposal in a landfill or the like. This invention is useful in safely disposing of environmentally hazardous organic wastes.

    摘要： A method is provided for the preparation of stable aqueous dispersions of non-solvated, un-neutralized, low amine, low acid number polymerized fatty acid polyamide resins. In the preferred method of this invention, a polymerized fatty acid polyamide resin which has been prepared so as to have a low acid and low amine number is liquified by heating the polyamide resin to a temperature where it is at or above its melting point. The liquified polymerized fatty acid polyamide resin is then blended with a predetermined amount of water which is heated to a temperature such that the resulting blend will have a temperature above the melting point of the polyamide resin. A cationic surfactant which is the salt of the amine of the formula:R--NH--CH.sub.2).sub.n.sbsb.1 (NH--CH.sub.2).sub.n.sbsb.2).sub.n.sbsb.3 NH.sub.2wherein R represents an alkyl having 16-20 carbon atoms and n.sub.1 and n.sub.2 are the same or different and each represents a whole number from 1-3 and n.sub.3 is 0 or 1, is included in the mixture. The resulting mixture is then subjected to sufficient comminuting forces to form an emulsion in which droplets of the polyamide resin have a volume average size distribution of about 20 microns or less in diameter and preferably 5 microns or less. The resulting emulsion is then cooled to a temperature below the melting point of the polyamide resin causing the emulsified droplets of the polyamide resin to solidify as finely divided particles which are dispersed uniformly through the aqueous phase. The resulting stable aqueous dispersions of the polymerized fatty acid polyamide resin which are obtained are especially useful for hot melted adhesive applications, when utilized in coatings, inks, and the like.

    摘要： A method is provided for the preparation of stable aqeuous dispersions of non-solvated, un-neutralized, low amine, low acid number polymerized fatty acid polyamider resins. In the preferred method of this invention, a polymerized fatty acid polyamide resin which has been prepared so as to have a low acid and low amine number is liquefied by heating the polyamide resin to a temperature where it is at or above its melting point. The liquified polymerized fatty acid polyamide resin is then blended with a predetermined amount of water which is heated to a temperature such that the resulting blend will have a temperature above the melting point of the polyamide resin. A cationic surfactant which is the salt of the amide of the formula:R--NH--CH.sub.2).sub.n.sbsb.1 (NH--CH.sub.2).sub.n.sbsb.2).sub.n.sbsb.3 NH.sub.2wherein R represents an alkyl having 16-20 carbon atoms and n.sub.1 and n.sub.2 are the same or different and each represents a whole number from 1-3 and n.sub.3 is 0 or 1, is included in the mixture.

    摘要： Disclosed is an industrial cleaning process in which a contaminant comprising soldering flux and/or adhesive tape residue is removed from a substrate contaminated therewith. The process comprises the steps of contacting the substrate with a terpene-based cleaning composition which is substantially free of water-soluble organic material; removing the composition and solubilized contaminant from the substrate by contact with water having a temperature of about 70.degree. F. to about 140.degree. F. for a period of time of no longer than about 10 minutes to provide a substrate having a contamination rating of no greater than about 14 micrograms NaCl equivalent/square inch (MIL-P-28809A), and to thereby form a mixture comprising the composition, contaminant and water. The process also comprises separating the water from said mixture, the separated water being substantially free of water-soluble organic material and having a chemical oxygen demand of no greater than about 1,000 ppm.
