    Abstract: The present invention relates to a process for the acid digestion of metal-containing compounds by leaching by means of an aqueous leachant, wherein the aqueous leachant i) contains an alkanesulphonic acid and, if appropriate, sulphuric acid and/or surfactant and/or ii) a mixture of an alkanesulphonic acid salt and sulphuric acid and also, if appropriate, surfactant. Furthermore, an aqueous leachant containing one or more alkanesulphonic acids and, if appropriate, sulphuric acid and/or surfactant and also an aqueous leachant containing one or more alkanesulphonic acid salts and sulphuric acid and, if appropriate, surfactant are also provided by the present invention.

    Abstract: La presente invención se refiere a un procedimiento para producir aminopolicarboxilatos a partir de un aminoácido que - en un primer paso procedimental, es hecho reaccionar con óxido de etileno para dar una mezcla intermedia que comprende la correspondiente dialcanolamina, y luego la mezcla intermedia, en un - segundo paso procedimental es transformada por vía catalítica haciendo uso de una base para dar el correspondiente aminopolicarboxilato, en el que - el aminoácido, antes de la reacción con óxido de etileno en el primer paso procedimental, es llevado a una neutralización parcial con 0,70 a 0,99 de equivalente de base por cada grupo ácido, o bien, en el primer paso procedimental, se usa un aminoácido que ya ha sido parcialmente neutralizado con 0,70 a 0,99 de equivalente de base por cada grupo ácido.

    Abstract: Tris-(2,2-di-substituted ethenylamino)-triazines (IA), with cyano, substituted carbonyl, optionally substituted aminocarbonyl or optionally esterified carboxyl, sulfo, sulfonyl and/or phosphono substituents, are new. Tris-(2,2-di-substituted ethenylamino)-triazines (IA) of formula (I) with specified substituents are new: Y = hydrogen (H); X = -CR =CR R ; R , R = -COOR , -COR , -CON(R )2, -CN, -SO2R , -SO2OR or -PO(OR )2; or R ,R = together form a ring; R = H or an optionally substituted (cyclo)aliphatic, araliphatic or aromatic group; R = H or an optionally substituted (cyclo)aliphatic, araliphatic or aromatic group. An Independent claim is also included for the use of enaminotriazines of formula (I) as ultraviolet (UV) filters in cosmetic or pharmaceutical formulations for protecting human skin or hair from sunlight, alone or with known UV-absorbing compounds for cosmetic formulations, in which (I) have the following definitions: Y = H or an optionally substituted (cyclo)aliphatic, araliphatic or aromatic group with up to 18 C atoms; X = -CR'=CR2 in at least one case, otherwise as Y; R = cyano, optionally esterified carboxyl, substituted carbonyl, optionally substituted aminocarbonyl or an optionally esterified sulfo, sulfonyl or phosphono group or 2 adjacent R groups form a ring; R' = H or a (substituted) (cyclo)aliphatic or aromatic group with up to 18 C atoms.
