    摘要： The present invention relates to a novel mixed glycerol ester composition comprising glycerol ester molecules comprising both valeric acid moieties and lauric acid moieties in the same molecule. The mixed glycerol ester composition can be useful for mitigating moderate to severe gut health challenges in animals and, in particular, it has shown to be effective for alleviating and/or mitigating coccidiosis in poultry.
    The present invention also relates to an animal feed additive comprising said mixed glycerol ester composition and to the use of said animal feed additive for improving the feed conversion ratio of animals.

    摘要： Use of a method for reduction of heavy end formation and catalyst loss in a hydroformylation process, wherein the method comprises the steps;

    a) Reacting an olefin and syngas in a reactor assembly (1) utilizing at least one catalyst and at least one ligand,
    b) Separating an obtained aldehyde from a mixture of aldehyde, catalyst, ligand and early heavy ends in a distillation unit (2),
    c) Entering the mixture of catalyst, ligand, early heavy ends and rest aldehyde into a short residence time evaporator unit (3) having at least a first rest aldehyde stripper stage (3a) and at least one last early heavy ends stripper stage (3b). Said evaporator units (3) being of a falling film and/or wiped film type,
    d) That the catalyst/ligand mixture from a lower end (3b1) of the at least one last early heavy ends stripping stage (3b) is entered into a cooling unit (4) immediately after stripping of early heavy ends.

    摘要： An antimicrobial composition for use as a preservative for waterborne coating compositions where said antimicrobial composition comprise at least two organic compounds in combination selected from a combination of compound group i) and compound group ii). Compound group i) is selected from the group consisting of dodecanoic acid, metal dodecaonoate, ammonium dodecanoate and a combination thereof, while compound group ii) is selected from the group consisting of propionic acid, metal formate, metal propionate, ammonium propionate and a combination thereof. The waterborne coating composition is based on an emulsion polymer resin based on a radical polymerization polymer selected from the group consisting of; vinyl acetate (PVA) polymer, vinyl acetate/ethylene (VAE) copolymer, vinyl acrylic copolymer, acrylic polymer, styrene acrylic copolymer, vinyl acetate/ethylene/vinyl chloride copolymer, vinyl acetate versatate and combinations thereof. The antimicrobial composition constitutes 0.3-3.0% by weight of the coating composition.

    摘要： The present invention refers to a polyvinyl chloride composition with high stability, said composition comprising: a) 100 phr (parts per hundred resin) of a polyvinyl chloride resin, b) 10-150 phr of pentaerythritol tetravalerate as plasticizer, said pentaerythritol tetravalerate having an acid value of less than 0.05 mg KOH/g and being obtained through esterification of valeric acid and high purity pentaerythritol having a purity of at least 98%, an ash content of less than 200 ppm and a dipentaerythritol content of 0.1-2 wt%, c) 0.3-14 phr of at least one stabilizer, and optionally d) at least one additive, wherein and the amount of free acid in the polyvinyl chloride composition is less than 30 ppm, preferably less than 20 ppm. The invention further refers to a polyvinyl chloride article comprising said composition and having an amount of free acid less than 30 ppm, preferably less than 20 ppm. The present invention also refers to a method for analyzing the amount of free acid in a polyvinyl chloride sample.

    摘要： The present invention refers to a plasticiser, said plasticiser being an ester formed by reaction of a pentaerythritol and a monocarboxylic acid, having 4-5 carbon atoms. In a further aspect the present invention refers to the use of said plasticiser in blends and in a PVC resin. The plasticiser of the present invention is a non-phthalic plasticiser that has proven to have shorter fusion time and higher plasticising efficiency compared to commercial non-phthalic PVC plasticisers.
