    摘要: A process for the production of compacted granules for use in a detergent composition by providing a homogeneous, solid, free-flowing premix to which a plasticizer or lubricant is added, and extruding the mixture through a perforated die under a pressure of from about 25 bar to about 200 bar to form strands of the mixture. The perforated die has an opening width corresponding to a predetermined size of the granules. After emerging from the perforated die, the strands are cut to the predetermined size of the granules by means of a cutting unit. The process enables the preparation of detergent compositions containing increased contents of surfactant components.

    摘要: This invention relates to an extruder having a granulating head for the granulation of a plastic molding compound which does not flow under gravity, more particularly an enzyme concentrate suitable for detergents, to granules having a particle size of at most 1 mm and, more particularly, at most 0.8 mm. To obtain uniform distribution of the molding compound to be processed over the entire cross-section of the molding plate, the granulating head has an externally arranged die plate support carrying perforated disks, a displacement cone arranged behind the die plate support and a preliminary distributor in the form of a perforated plate arranged between the die plate support and the displacement cone. In addition, the die plate support has bore-like passages each with a perforated disk which is arranged at the front end thereof and of which the bores have a rear zone of relatively large cross-section and a front zone of relatively small cross-section, the transitional zone between the rear zone and the front zone being inclined at an angle of 55.degree. to 65.degree. C. relative to the horizontal.

    摘要: A free-flowing granulate of a powder-form or fine-grained component and a liquid component; the granulate containing at least 20% by weight of the liquid component, is prepared by moving the powder-form or fine-grained component in a mixer-granulator, adding the liquid component while mixing until a moist granulate having a particle size of at most 1.5 mm is obtained, subsequently coarsening the granulate thus obtained with an increase in temperature to a particle size of from 0.4 to 4 mm and optionally coating this coarse granulate with another powder-form and/or fine-grained component at 60.degree. to 90.degree. C. The optionally coated granulate is converted by lowering the treatment temperature into a dry-looking, free-flowing, coarse-grained product, which if desired, may be coated with another powder-form and/or fine-grained material. Despite the high percentage of a liquid component, the granulate thus obtained appears as a dry granulate and is free-flowing.

    摘要: The aliphatic primary alcohols are reacted with a glycose, more especially glucose, in the presence of an acidic catalyst in certain process steps so that particularly light-colored and alkali-stable alkyl glucosides are obtained after a subsequent, compulsory bleaching step, which represents an improvement over known direct synthesis processes. The process may be carried out both on a laboratory scale and also on an industrial production scale.

    摘要: A method for the production of granular sodium perborate tetrahydrate is disclosed herein. The method includes the steps of adding 0.3-5% by weight of a sodium salt or a potassium salt of a polymeric carboxylic acid to powdered perborate tetrahydrate, softening the mixture by heating under pressure to form a plastically deformable mass, deforming the plastically deformable mass into thin strands by pressing, and comminuting the strands into granular form. The perborate tetrahydrate may be de-watered to produce granular perborate monohydrate. The final granular products exhibit high abrasion resistance and are preferably used in washing and cleaning agents.
