    摘要： A plurality of stages is employed to reduce the total organic carbon (TOC) content of a brine by-product stream to produce a recyclable brine stream having a TOC content of less than about 10 ppm. In a first stage treatment, a brine by-product stream may be subjected to chlorinolysis at a temperature of less than about 125 0C to obtain a chlorinolysis product having a TOC content of less than about 100 ppm, which may be treated in a second stage with activated carbon to obtain a TOC content of less than about 10 ppm. The chlorinolysis may be a reaction with sodium hypochlorite, which may be produced in situ by treatment of the brine by-product stream with chlorine gas and sodium hydroxide. The brine by-product stream may contain a high amount of difficult to remove glycerin, such as a brine by-product stream from the production of epichlorohydrin from glycerin.

    摘要翻译： 采用多个阶段来降低盐水副产物流的总有机碳（TOC）含量，以产生TOC含量小于约10ppm的可再循环盐水。 在第一阶段处理中，盐水副产物流可以在小于约125℃的温度下进行氯解，得到TOC含量小于约100ppm的氯解产物，其可以在第二阶段 用活性炭获得小于约10ppm的TOC含量。 氯解可能是次氯酸钠的反应，其可以通过用氯气和氢氧化钠处理盐水副产物流而原位产生。 盐水副产物流可能含有大量难以除去甘油，例如从丙三醇生产表氯醇的盐水副产物流。

    摘要： Inorganic oxide supported chromium-containing catalysts are improved by depositing the chromium onto the inorganic oxide support in the vapor phase rather than as an inorganic or organic compound. Polymers resulting from polymerizing one or more .alpha.-olefins in the presence of such catalysts exhibit a higher molecular weight as compared to those polymers prepared in the presence of such chromium-containing catalysts prepared in the conventional manner.

    摘要： Copper is removed from spent solutions of complexing agents containing cuprous aluminum tetrahalide, such as CuAlCl.sub.4.toluene by (1) contacting said solutions with water so as to form a precipitate of cuprous halide, an aqueous phase and an organic phase; (2) oxidizing the cuprous halide to cupric halide thereby rendering it water soluble; (3) separating the organic phase and aqueous phase, (4) contacting the aqueous phase with an environmentally suitable metal higher than copper from the electromotive series, such as aluminum, thereby precipitating copper metal and (5) separating the precipitated copper metal from the aqueous salt-containing mixture.Alternatively, the spent complex solutions can be contacted with 1 molar to 6 molar aqueous solution of a non-oxidizing acid such as HCl thereby eliminating the necessity of the oxidizing step (2) since the cuprous halide is soluble in the acidified aqueous phase.

    摘要： The invention is an adhesive composition comprising: a) an isocyanate functional polyether base prepolymers having a z molecular weight average (Mz) of about 10,000 to about 80,000 g/mole; a carbon black having an average oil absorption number of at least about 80 to at most about 400 cubic centimeters of dibutyl phthalate per 100 grams of the carbon black; (c) reactive silicon in an amount from about 0.001% to about 10% by weight of the adhesive composition; and (d) one or more catalysts for the reaction of isocyanate with hydroxyl groups. The adhesive compositions of the invention surprisingly may have improved sag performance (i.e., decreased sag) when heated, while also making them more easily pumped.
