A method is described for producing acyl glycinate salts of formula (II) in which Rrepresents a saturated linear or branched alkyl radical comprising 1 to 21 carbon atoms or a monounsaturated or polyunsaturated linear or branched alkenyl radical comprising 2 to 21 carbon atoms, and B represents a cation, and/or the corresponding protonated acyl glycinic acid. Said method is characterized in that one or more fatty acid monoethanol amides of formula (I) in which Rhas the meaning indicated above is/are oxidized with oxygen in the presence of an optionally supported bimetallic catalyst consisting of gold and a metal from group VIII of the periodic table in the alkaline medium in order to obtain one or more acyl glycinate salts of formula (II). In order to produce the protonated acyl glycinic acids, the acyl glycinate salt/s of formula (II) is/are additionally reacted with an acid.

The invention relates to methods for producing supported gold catalysts from a porous metal oxide support and a chloroauric acid precursor, wherein the support is placed in contact with the aqueous solution of the chloroauric acid precursor. The invention also relates to a metal oxide supported gold catalyst and its use in the oxidation of alcohols, aldehydes, polyhydroxy compounds and carbohydrates.

A process is described for preparing acylglycinate salts of the formula (II) in which Ris a saturated linear or branched alkyl radical having from 1 to 21 carbon atoms or a mono- or polyunsaturated linear or branched alkenyl radical having from 2 to 21 carbon atoms, and B is a cation derived from a base, and/or the corresponding protonated acylglycines, characterized in that one or more fatty acid monoethanolamides of the formula (I) in which Ris as defined above is oxidized with oxygen in the presence of a transition group metal catalyst in an alkaline medium to give one or more acylglycinate salts of the formula (II), and, in the case of preparation of the protonated acylglycines, the acylglycinate salt(s) of the formula (II) is additionally reacted with an acid.

Economic production of solid particles from a liquid medium, which involves the liquid medium being formed as a cohesive liquid jet and being divided into defined sections ( ) by a dividing device which is moved continuously in one direction in a cutting plane ( ) is achieved, according to the invention, while minimizing cutting or spray losses caused by the dividing of the liquid jet ( ), by the fact that a plurality of liquid jets ( ) are provided, beneath which a common dividing device ( ) is arranged, the liquid jets ( ) being inclined with respect to the direction of movement of the dividing device ( ) in such a way that each of the liquid jets ( ) forms an acute angle (&bgr;) with the direction of movement of the dividing device ( ).
