    Abstract: Disclosed is a method for producing (meth)acrylates of C10 alcohol mixtures by reacting (meth)acrylic acid with an isomer mixture of C10 alcohols comprising 2-propylheptanol as the main isomer and at least one of the C10 alcohols 2-propyl-4- methylhexanol, 2-propyl-5-methylhexanol, 2-isopropylheptanol, 2-isopropyl-4- methylhexanol, 2-isopropyl-5-methylhexanol, and/or 2-propyl-4,4-dimethylpentanol in the presence of at least one acid catalyst and at least one polymerization inhibitor and in the presence of a solvent forming an azeotrope along with water, removing the azeotrope by distillation and condensing the same such that the condensate is decomposed into an aqueous and an organic phase. According to said method, a) the esterification process is carried out in a reactor comprising a circulating evaporator, b) in the presence of a solvent, and c) the raw product is purified in a subsequent pure distillation process.

    Preparation of urethane (meth)acrylates, useful for coating e.g. wooden substrates and cellulose fibers, comprises reaction of components, e.g. isocyanate and polyalkyleneoxide polyether in presence of at least one reactive solvent

    Abstract: Preparation of urethane (meth)acrylates (I) comprises reaction of the components (A) e.g. at least an isocyanate (a), polyalkyleneoxide polyether (b), hydroxyfunctions (meth)acrylate (c), optionally a compound (d) with at least a group reactive opposite isocyanate and an acid function, optionally a base compound (e) (if (d) is present), optionally at least a mono alcohol (f), and optionally a compound (g) with a primary and/or secondary amino group, in presence of a reactive solvent (B); and adding isocyanate to the mixture preferably containing (b), (c) and optionally (d). Preparation of urethane (meth)acrylates (I) comprises reaction of the components (A) in the presence of at least one reactive solvent (B), where (A) is at least an isocyanate (a) with at least 2 isocyanate functions, at least a polyalkyleneoxide polyether (b) with at least 2 hydroxyfunctions, at least a hydroxyfunctions (meth)acrylate (c) with a hydroxyfunction and at least (meth)acrylate function, optionally at least one compound (d) with at least an isocyanate reactive group and at least an acid function, optionally at least a base compound (e) (if (d) is present) for the neutralization or partial neutralization of the groups of acids of the component (d), optionally at least a mono alcohol (f), which exhibits exactly a hydroxy function, and optionally at least a compound (g) with at least a primary and/or secondary amino group; and adding isocyanate to the mixture preferably containing (b), (c) and optionally (d).

    Abstract: Se describe un método para producir (met)acrilato de mezclas de alcoholes de C10 mediante la reacción del ácido (met)acrílico con una mezcla de isómeros de alcoholes de C10 que contiene 2-propilheptanol como el isómero principal y al menos uno de los alcoholes de C10 2-propil-4-metilhexanol, 2-propil-5-metilhexanol, 2-isopropilheptanol, 2-isopropil-4-metilhexanol, 2- isopropil-5-metilhexanol y/o 2-propil-4,4-dimetilpentanol en presencia de al menos un catalizador ácido y al menos un inhibidor de la polimerización y en presencia de un solvente que forma un azeótropo junto con agua, la separación del azeótropo por destilación y la condensación del mismo de modo que el condensado se descomponga en una fase acuosa y una orgánica. De acuerdo con el método, a) el proceso de esterificación se lleva a cabo en un reactor que comprende un evaporador de circulación, b) en presencia de un solvente, y c) el producto crudo se purifica en un proceso de destilación para purificación subsiguiente.
