  • Publication number: 20040045610
    Abstract: The invention relates to a liquid distributor in the form of a channel distributor with drainage outlets. To ensure that the uniformity of distribution of the liquid is largely independent of disturbance factors, for example blockages of the drainage outlets, the drainage outlets are in the form of drainage pipes having a cross-section which tapers in the shape of a nozzle. The inner wall of the nozzle-like tapering of the drainage outlets being made of plastic, or another material resistant to the adherence of solids which would block the flow of liquid through the outlet.

  • Patent number: 5510482
    Abstract: The crude reaction products from the synthesis of alkyl glycosides are bleached by kneading the material substantially freed from the excess fatty alcohol and containing at most limited quantities of water with an oxidizing agent at such elevated temperatures that the reaction mixture lends itself to plastic processing. Temperatures of from about 50.degree. to 150.degree. C. are particularly suitable, although it is best to apply temperatures in the range from about 80.degree. to 100.degree. C. using aqueous hydrogen peroxide as the oxidizing agent. Bleaching is carried out under basic conditions, optionally by addition of an alkaline compound, such as for example 50% sodium hydroxide solution. The bleached product accumulates in the form of a solid. It is preferably mixed with typical compatible solids, more particularly typical constituents of detergents and cleaning preparations, to form a solid and preferably free-flowing alkyl glycoside compound.

  • Patent number: 5324871
    Abstract: The invention relates to a process for the hydrogenation of native fats, oils and fat derivatives, such as fatty acids and fatty acid esters, to fatty alcohols in a fixed-bed reactor, more particularly in co-current, hydrogen being recirculated in a stoichiometric excess, more particularly in an excess of 10 to 100 fold, and the fat, oil or fat derivative passing through the reactor only once. To minimize the specific hydrogen demand without having to accept significant losses in regard to specific reactor load, product selectivity and catalyst life, the hydrogen is passed successively through at least two fixed-bed reactors 4,10 without the gas issuing from the reactors 4 and entering the following reactors 10 being cooled and the fat, oil or fat derivative is simultaneously introduced into the reactors 4,10.

  • Patent number: 5318733
    Abstract: 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.

  • Patent number: 5283024
    Abstract: 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.
