Abstract: An alloy for grain refining of copper materials consists of copper or a copper alloy containing (a) 0.01 to 25 % calcium, (b) 0.01 to 15 % boron. The alloy permits remarkably uniform and efficient grain refining of copper materials, and no large foreign nuclei are left behind in the relevant material.

Abstract: The description relates to a process for producing aromatic nitriles from their corresponding aldehydes, in which the latter are caused to react with ammonia at temperatures of 200 to 500 DEG C in the gas phase in the presence of a catalyst based on molybdenum nitride of the general formula MoNxOy in which x = 0.25 to 1.0 and y = 0 to 1.0. It is thus possible to produce aromatic nitriles from the corresponding aldehydes with yields and selectivities of up to 98 % with conversions of up to 100 %.

Abstract: Process as described based on the use of ammonia salts containing dicyandiamide, whereby the surface of the ammonia fertilizer grain is sprayed with a molten polyethylene glycol at a temperature of 50o to 90oC, after which the dicyandiamide is applied to the grain and the granular material is cooled until the polyethylene glycol hardens again. The granular material thus produced has a slight tendency to agglomerate and to the attrition of the dicyandiamide.

Abstract: In order to fractionate viscous silicones, oily or polymer diorganosilicones with a chain length from 2 to 10.000 are continuously separated with condensed hydrocarbons such as ethane, propane and n- or i-butane or their mixtures into a head and a bottom product, preferably in an extraction column, at temperatures between 25 and 250 DEG C, pressures between 20 and 500 bars and a gas density > 160 kg/m . In order to avoid viscosity-caused problems, an organic solvent in the form of a C5-8-alkane or up to 85 % by weight of the condensed gas (mixture) can be added to the starting materials before the fractionation. This process enables high-grade viscous silicone fractions to be obtained, with a chain length from 200 to 10,000 and/or a viscosity from 100 to 500,000 mPas, as well as a total D4 to D20 oligomer content below 0.05 % by weight.

Abstract: The invention concerns a process for preparing calcium cyanamide by reacting urea with an oxygenous calcium compound in at least two steps: a) in a first step the reaction components are reacted by condensation and/or circulation or by applying them to a hot surface at temperatures of between 120 and 500 DEG C until a solid forms; and b) the resultant solid reaction mixture is then calcined at temperatures of between 600 and 900 DEG C. In this way high yields and charges of calcium cyanamide can be obtained without necessitating complicated reprocessing of the reaction product after the first or second step.
