    摘要： Liquid varnish coating compositions having a low or nil solvent content, comprising a mixture of binders and optionally conventional auxiliary agents, which contain, as the binder, a mixture of:A) glycidyl esters produced in the usual manner by the reaction of esterification products containing carboxyl groups with an excess of a 2,3-epoxyhaloalkane in the presence of reactive agents which split off hydrogen halide; andB) one or more polyamines with at least 3 active hydrogen atoms linked to nitrogen atoms, wherein the nitrogen atoms are bound to aliphatic and/or cycloaliphatic residues which, in turn, can optionally be bound to an aromatic residue,In such an amount that 0.8-1.5 amino hydrogen equivalents are present for one epoxide equivalent of the glycidyl esters.

    摘要： Transition metals may be recovered from a salt-containing mixture containing at least one transition metal compound, salts, and organic compounds by separating from the salt-containing mixture a mixture of the transition metal compound and the salts. This mixture, together with any organic impurities, is introduced into a combustion zone, and the flue gas/salt mixture leaving the combustion zone is quenched with water. The combustion residue, containing the transition metal, is separated from the resulting quench solution, dried, and converted to fresh catalyst.

    摘要： A process for preparing an alkoxysilane with an acidic chloride content of less than 10 ppm by weight, comprising:reacting a chlorosilane with an alcohol in a water-free and solvent-free phase to form a product mixture containing alkoxysilane and residual acidic chloride, with removal of resultant hydrogen chloride from the product mixture,then adding liquid or gaseous ammonia, in an amount corresponding to a stoichiometric excess, based on the content of acidic chloride, to form an ammonia-containing product mixture,treating the ammonia-containing product mixture at a temperature between 10 and 50.degree. C., wherein the ammonia and acidic chloride undergo neutralization, to form a crude product, and optionally, then separating off a salt formed in the course of neutralization, from the crude product, andrecovering the alkoxysilane by distilling the crude product.
