    摘要: A phosphate-reduced, granular free-flowing detergent containing (a) from 5 to 40% nonionic surfactant, (b) from 3 to 20% anionic surfactant, (c) from 15 to 50% zeolite, (d) from 0.5 to 15% homopolymeric or copolymeric carboxylic acid or alkali metal salts thereof and (e) from 10 to 72.5% detergent constituents which are stable under spray-drying conditions, with the proviso that the detergent comprises a mixture of two powder components (A) and (B) in a weight ratio of from 1:5 to 3:1, component (A) containing from 50 to 100% of constituent (a), from 80 to 100% of constituent (c) and from 50 to 100% of constituent (d). Component (A) has an average particle size of from 0.4 to 0.8 mm and a powder density of from 500 to 800 g/l. Component (B) contains from 80 to 100% of constituent (b) and 100% of constituent (e), has a powder density of from 300 to 500 g/l and differs in its particle size distribution by at most 50% from the particle size distribution of component (A).

    摘要: A process for the production of pourable, free-flowing granules which are suitable for use as wetting agents, detergents or cleaning products from aqueous solutions or suspensions of such materials in a fluidized-bed spray granulation apparatus employing a hot fluidizing gas. The aqueous selections or suspensions are dried with superheated steam as the fluidizing and drying gas wherein the drying step is carried out in a closed-loop system comprising a steam circuit from which the water evaporated from the aqueous solutions or suspensions of starting materials is removed as a partial stream and the thermal energy released is returned to the steam circuit. The granules are discharged from the granulation apparatus before they can be damaged by heat.

    摘要: A process for the continuous processing of vinyl polymer latices to produce thermoplastically processible vinyl polymer powder by coagulating a stream of a vinyl polymer latex by the addition of a stream of a coagulant with intensive mixing and shearing in a cascade of vessels at an average residence time per vessel of 10 to 60 minutes and at temperatures from 50 to 120.degree. C., volatile auxiliary substances and residual monomers in the polymer being optionally removed by steam distillation and part of the serum separated from the vinyl polymer being added to the stream of coagulant.
