    摘要: A process for reducing volatile, odor-causing impurities in alkoxylated alcohols comprising adjusting the pH of an alkoxylated alcohol product mixture containing such impurities to a range of from about 7 to about 8.5 to produce an alkaline alkoxylated alcohol mixture and steam stripping the alkaline alkoxylated alcohol mixture at an elevated temperature for a period of time sufficient to produce a steam stripped alkoxylated alcohol containing a reduced amount of odor-causing impurities.

    摘要: The present invention provides a method for obtaining reduced coenzyme Q 10 which is useful as an ingredient in foods, functional nutritive foods, specific health foods, nutritional supplements, nutrients, drinks, feeds, cosmetics, medicines, remedies, preventive drugs, etc. suited for a commercial scale production in high quality and efficiently.
    The high-quality oily reduced coenzyme Q 10 which has low viscosity and thereby easily handled may be produced by separating an aqueous phase from the reaction mixture obtainable by oily reacting oxidized coenzyme Q 10 with a reducing agent in water, or by distilling off an coexisting organic solvent at or above the melting temperature of reduced coenzyme Q 10 in concentrating the organic phase containing reduced coenzyme Q 10 . Moreover, a solution or slurry of reduced coenzyme Q 10 may be obtained by adding a desired solvent to the obtained oily product, or a solid of reduced coenzyme Q 10 may be produced by contacting the oily product with a seed crystal.

    摘要: The application relates to a process which comprises:

    A) forming a reaction product composition comprising arylcarboxylic acid or substituted arylcarboxylic acid in a polar organic solvent medium by palladium-catalyzed hydrocarboxylation of an arylolefin or substituted arylolefin in a liquid medium comprising polar organic solvent, water, HCl, and at least one ether;
    B) mixing with said reaction product composition an aqueous solution of inorganic base to form a mixture comprising an aqueous phase containing dissolved inorganic salt of said arylcarboxylic acid or substituted arylcarboxylic, and before and/or during and/or after such mixing, distilling a substantial portion of the ether from the reaction mixture, such that a mixture of residual organic phase and such aqueous phase remain as a distillation residue;
    C) separating the phases from each other;
    D) distilling residual organic impurities from the aqueous phase and providing an aqueous solution having a concentration in the range of 10 and 35 wt%, by, if necessary, adjusting the concentration of such aqueous solution by removal therefrom or addition thereto of water;
    E) washing the aqueous solution with non-polar organic solvent at least twice;
    F) mixing non-oxidizing mineral acid with the aqueous phase in the presence of non-polar liquid solvent to form (i) an organic phase composed of a solution of arylcarboxylic acid or substituted arylcarboxylic acid in non-polar liquid organic solvent and (ii) an aqueous phase;
    G) separating the phases from each other; and
    H) crystallizing arylcarboxylic acid or substituted arylcarboxylic acid from organic solvent.

    摘要: Beim neuen Verfahren zur Reinigung eines Alkylenoxid-­Adduktes, das unter Verwendung von halogenhaltigen Metallkatalysatoren hergestellt worden ist und Halogen enthaltende Verbindungen sowie Metalle als Verunreinigung enthält, wird das zu reinigende Alkylenoxid-Addukt mit Alkalimetallverbindung in Überschuß behandelt und die erhaltene alkalische Mischung mit einer Säure auf einen pH-Wert von höchstens 7 eingestellt, mit der Maßgabe, daß in der nun vorliegenden Produktmischung eine Wassermenge von mindestens 0,1 Gew.-%, bezogen auf das Gewicht des Produktes, anwesend ist. Diese Produktmischung wird von Wasser und anderen Lösungsmitteln befreit, wobei die im Alkylenoxid-Addukt unlöslichen Salze grob-kristallin ausfallen und zur Gewinnung des angestrebten reinen Alkylenoxid-Adduktes leicht abgetrennt werden können.
