    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: Anionic surfactant concentrates in the form of solid free-flowing powders and/or granules which may also be present as compounds in admixture with other auxiliaries and/or useful materials suitable for use in detergents and/or cleaning products and which have apparent densities of at least about 150 g/l are produced by hot drying of the water-containing preparations with superheated steam as the drying gas. Preferred apparent densities are above about 200 g/l and are preferably at least about 350 g/l. In addition, the pourable and free-flowing material is preferably in the form of a substantially dust-free material through the presence of dust-binding auxiliaries and/or useful materials and/or by regulation of the residual water content. In one preferred embodiment, the anionic surfactant concentrate is in the form of porous carrier beads with an absorbent porous inner structure.

    摘要: A process for the production of wetting-, washing- or cleaning-active anionic surfactant salts by reacting inorganic or organic bases with anionic surfactant intermediates containing hydrophilic negatively charged groups attached to hydrophobic hydrocarbon radicals. The salts are combined in a spray which is introduced into an inert gas phase of superheated steam whereby the spray is at least partly dried. In an embodiment of the process, the anionic surfactant intermediates are neutralized during the spraying step to form the salts.

    摘要: The invention relates to a solid material (primary drying product) containing alkali metal silicate with a modulus (molar ratio of SiO.sub.2 to M.sub.2 O, M=alkali metal) of 0.8 to 4 in homogeneous admixture with other inorganic and/or organic useful materials and/or auxiliaries, which has been dried from a finely sprayed aqueous preparation of mixtures of the alkali metal silicates and the inorganic and/or organic useful materials and/or auxiliaries by means of a hot gas stream. The solid material according to the invention is characterized in that, as a primary drying product in homogeneous admixture with the alkali metal silicate, it contains at least 10% by weight of water-soluble inorganic and/or organic salts, has apparent densities of at least 150 g/l, possesses a microporous absorbent internal structure and has been dried with superheated steam as the hot gas stream. The invention also relates in particular to detergent builder systems based on multicomponent systems containing this overdried alkali metal silicate and to their use for subsequent impregnation with other free-flowing useful materials and mixtures thereof from the field of detergents and to the detergents obtained.
