摘要： The invention relates to a method for producing shaped inorganic cyanide bodies, especially made of alkaline metal cyanides and alkaline earth metal cyanides, by pressing particulate inorganic cyanide obtained by means of a crystallization method. According to the invention, a cyanide crystallate separated from a mother liquor by means of a solid-liquid separation device and containing 2-15 wt. % water is fed to a forming device without the addition of an auxiliary forming agent and placed under pressure and compressed to form shaped bodies containing 0.1-12 wt. % water. The amount of water contained by the shaped bodies is always less than that contained in the crystallates used for the production thereof. Preferably, the crystallite is pressed out of a rotary filter or a centrifuge at a temperature of more than 40° C. to form shaped bodies containing 0.2-6 wt. % residual water. The inventive method can be carried out in a more economical manner than previously known methods using dried cyanide. The invention also relates to shaped inorganic cyanide bodies obtained according to said method.

wherein the at least one comonomer is selected from pentaerythritol acrylate and pentaerythritol acrylate derivatives and also optionally acrylic acid; and/or

b) at least one polyvinyl alcohol P2 having a degree of hydrolysis in the range from 87 to 95 mol%;

wherein, in addition to the at least one polyvinyl alcohol copolymer P1 and/or the at least one polyvinyl alcohol P2, the polymer composition can additionally optionally contain additive substances;
wherein the polymer composition, in the case in which it comprises at least one polyvinyl alcohol copolymer P1 and no polyvinyl alcohol P2, has a content of repeating units of the at least one comonomer in a range from in total 10% to 20% by weight, based on the total weight of polyvinyl alcohol copolymer P1; and
wherein the polymer composition, in the case in which it comprises at least one polyvinyl alcohol copolymer P1 and at least one polyvinyl alcohol P2, has a content of repeating units of the at least one comonomer in a range from in total 10% to 20% by weight, based on the total weight of polyvinyl alcohol copolymer P1 and polyvinyl alcohol P2. The water-soluble receptacle can advantageously be used in a method for producing a coloured aqueous alkali metal cyanide solution. To this end, the water-soluble receptacle can be provided together with an alkali metal cyanide compound in the form of a composition Z1.

摘要： The invention relates to a process for the direct preparation of alkali metal cyanide and alkaline earth metal cyanide granules from an HCN-containing gas and an aqueous solution or suspension of an alkali metal or alkaline earth metal hydroxide. Reaction is performed in a reactor for fluidised bed spray granulation, wherein a solution or suspension of the hydroxide is sprayed onto seed granules of the cyanide being prepared and at the same time a hydrogen cyanide-containing gas is supplied to the reactor and water is evaporated by means of a fluidising gas. The preferred fluidising gas is steam. The reaction gases from a BMA or Andrussow process may be quenched with water and the gas mixture used as fluidising gas. By using a CO2-free HCN-containing gas, alkali metal cyanide granules with an outstanding combination of properties, including a concentration of alkali metal ' carbonate and alkali metal formate together of less then 0.4 wt.%, are obtainable.
