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.
Abstract: A package for pourable substances like liquids or loose fine granulates includes an inner plastic container holding the substance to be packed and a cardboard envelop surrounding the plastic container, wherein the plastic container is a thin-walled hollow plastic body made by a blowing process. The envelope, when set up as a package, is at least locally in contact with the plastic container and is fitted with apertures facilitating its holding the plastic container. The hollow plastic body has at least two straight surfaces substantially forming one edge, in which a region of the associated side has a recess, and apertures in the cardboard envelope formed as a supporting case correspond to the recess in the edge region of the hollow plastic body to provide a handle.
Abstract: A process is described for rock consolidation, e.g. in tunnel construction and mining, by injection of aqueous preparations of melamine resin condensates and/or urea formaldehyde condensates together with an acid curing agent. The process is characterized by the use of aqueous solutions of hydrogen sulfate salts, especially solutions of alkali and/or ammonium bisulfates, as curing agents. The curing agent solutions can contain additional auxiliary agents and active substances such as corrosion inhibitors, structurizers and adhesion agents. Preferred resin solutions for consolidation with these aqueous curing agents contain added zeolite NaA and/or hydrosodalite for increasing their serviceability, and especially for prolonging their storage life.

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.
Abstract: A process for the production of a surfactant mixture for use in enhanced oil recovery wherein the surfactant mixture comprises an alkyl ether sulfonic acid or salt thereof as a principal constituent and at most a substantially equal quantity of alkoxylated alcohol. The surfactant mixture is prepared by reacting an alkyl ether sulfate with a stoichiometric excess of an alkali metal sulfite solution at about 160.degree. C. to 220.degree. C. under mildly alkaline pH conditions, and then extracting sulfate salt therefrom using a substantially water-insoluble alcohol at a lowered temperature.
Abstract: A process for the production of pourable foam inhibitor granules comprising forming an aqueous solution of a mixture of an alkali metal carboxymethyl cellulose and a nonionic cellulose ether and maintaining the aqueous solution at slightly elevated temperature until the viscosity is at least 60% of the viscosity obtained by complete swelling of the solution, adding a water insoluble foam inhibitor and a phosphate-free mixture of at least two of an alkali metal silicate, an alkali metal carbonate and an alkali metal sulfate into the aqueous mixture which is then spray-dried to form the pourable foam inhibitor granules.The invention also relates to the pourable foam inhibitor granules produced by the above process.

Abstract: The description is of a process for the production of light-colored lower alkane sulfonic acids, especially methane sulphonic acid, by reacting the corresponding alkyl halide with alkaline halides and obtaining the free alkane sulphonic acid. In the process of the invention, the reaction is performed as a liquid/liquid reaction at temperature not exceeding 120 degrees C., and at such high pressures that even the lower alkyl halide is in the liquid phase at the reaction temperature, the aqueous reaction mixture is reduced by water content of some 50% wt. at the most, the alkaline sulphonic acid is liberated from its alkaline salt by the addition of HCl, the solid salt phase still remaining in the reaction mixture is separated out and the free alkaline sulphonic acid is obtained from the liquid phase.
