摘要： A method for the production of catalytically active coatings on shaped articles of aluminum oxide for the production of hydrogen cyanide according to the BMA method. A suspension is used for the coating which suspension contains at least one platinum metal and aluminum in finely divided elementary form in a carrier liquid. According to especially preferred embodiments, the suspension additionally contains glass frits or organic silicon compounds. After the moistening of the shaped article and evaporation of the carrier liquid, the catalyst is formed during heating to 1000.degree. to 1350.degree. C. in the presence of nitrogen and/or ammonia.Essential advantages of the method over the previously known method of coating with solutions of Pt and Al compounds are: the application of different coating thicknesses are possible in a single coating stage, the previously-necessary hydrogenation stage after each impregnation is eliminated and the health risk is reduced.

摘要： To obtain a cyanogen chloride which is practically free from water and preferably also free from hydrogen cyanide, hydrogen chloride and organic compounds, the crude cyanogen chloride is fractionally distilled. The return is led in countercurrent flow to the crude gas, thereby takes up the impurities and is further evaporated in the lower portion of the column, respectively in a special apparatus, by a liquid whose temperature is higher than the boiling temperature of cyanogen chloride. Thereby this liquid also takes up the impurities. The purification action is aided by a wash for the crude cyanogen chloride connected in series before it enters the fractionating column. It is very advantageous to combine the process with a plant for the production of cyanogen chloride.
摘要翻译： 为了获得实际上不含水的氰氯化物，优选也不含氰化氢，氯化氢和有机化合物，分馏了粗氯化氰。 回流以逆流流向粗气体，从而占据杂质，并在专用设备中通过温度高于氯化氰沸点的液体分别在塔的下部蒸发。 因此，这种液体也会占据杂质。 纯化作用通过在进入分馏塔之前串联连接的氯化氰原料的洗涤来辅助。 将该方法与用于生产氯化氰的设备相结合是非常有利的。

摘要： Suspension or solutions of cyanuric chloride in water are prepared at high mixing velocities and low temperatures with resulting low degree of hydrolysis by introducing liquid cyanuric chloride through a nozzle in the upper portion of the mixing apparatus in countercurrent flow to upwardly flowing water introduced from at least one lower nozzle above a breast shaped constriction in the lower, open portion of the apparatus. In this way the chamber walls are always covered with an unbroken layer of liquid. The process can be carried out at normal, reduced or elevated pressure. At reduced pressure by evaporation of the water there is simultaneously a cooling of the system.
