Abstract: According to the invention, oxyalkylates of aliphatic or cyclic, primarily primary diamines or polyamines, or block polymers (having recurring structural units of the abovementioned oxyalkylate type) produced by prior linking of such oxyalkylates with dicarboxylic acids, are converted into novel substances which are suitable for a very wide variety of areas of application in the field of interface-active agents and can be employed, for example, in the preparation of azo pigments to improve the coloristic properties, by esterification of the terminal hydroxyl group in these aminoxyalkylates using fatty acids or aromatic carboxylic acids and/or resin acids, and, if appropriate, subsequent reaction of free hydroxyl groups which are still present with dicarboxylic acids and sulfite to form the corresponding monoester (containing anionic radicals).

Abstract: According to the invention, addition of one or more surfactants having a cloud point in aqueous solution to an aqueous suspension of a solid gives after the isolation of the solid at a temperature above the cloud point aqueous press cakes containing a large amount of this solid. The direct processing of press cakes as obtained for example after the synthesis and isolation of dyes or pigments to give practical aqueous pastes or dispersions requires a minimum solids content in the press cakes. The minimum content is frequently not obtained when conventional methods of isolation are used, so that it is necessary to proceed via the indirect route of drying to obtain the powders and redispersing the powders. By using the process according to the invention it is possible to cut out the costly indirect route or, if desired, to reduce the expense of drying to obtain powders by an appreciable margin.

Abstract: The invention relates to novolak oxyalkylate mixed esters which, on the one hand, contain benzoyl and/or naphthoyl radicals and, on the other hand, contain maleic acid and/or sulfosuccinic acid half-ester groups. They are obtained by reacting novolak oxyalkylates with benzoic acid and/or naphthoic acid or with its anhydride or chloride on the one hand and maleic anhydride on the other hand and, if appropriate, reacting the maleic acid half-ester groups with sulfites to give sulfosuccinic acid half-ester groups. These compounds are highly suitable for use as dispersing agents for the preparation of low-foam dispersions of pigments, dyestuffs and other agents and as emulsifying, leveling and dyeing auxiliaries.
