摘要： Blue iron hexacyanoferrate-III pigments are produced by a process wherein complex iron-II hexacyanoferrate-II (Berlin white) is prepared by electrolysis of an aqueous catholyte solution containing (a) an iron-II salt, (b) an alkali metal salt, an ammonium salt or a mixture of these, and (c) hydrogen cyanide, in an electrolysis cell in which the anode chamber and cathode chamber are separated by an ion exchange membrane, using an electrically conductive aqueous liquid in the anode chamber, and the iron-II hexacyanoferrate-II obtained is then converted to the blue pigment.The process gives Berlin white, which is substantially free from salt, in high yield and high purity. Pollution caused by the process is very low, since only a small amount of salt is produced. Compared with the corresponding blue pigments produced by prior art processes, the pigments obtained give purer colorations with better gloss, and are of higher color strength.
摘要翻译：通过电解含有（a）铁-II盐，（b）碱金属盐的水性阴极电解液的方法制备复合铁 - 六氰基铁酸盐-II（柏林白）的方法制备蓝色六氰合铁酸盐III- 铵盐或它们的混合物，和（c）氰化氢在电解池中，其中阳极室和阴极室由离子交换膜分离，使用阳极室中的导电含水液体，铁 -II六氰基铁酸盐-II然后转化成蓝色颜料。该方法给出柏林白色，其基本上不含盐，以高产率和高纯度。该过程造成的污染非常低，因为只产生少量的盐。与通过现有技术方法生产的相应的蓝色颜料相比，获得的颜料产生更好的着色，并具有较高的着色强度。

摘要： Blue iron hexacyanoferrate-III pigments (I) are prepared by anodic oxidation of metallic iron in hydrogen cyanide, or a reaction medium containing hydrogen cyanide, at pH 8.The process gives readily dispersible pigments (I) which are of high color strength and give brilliant, glossy colorations.
摘要翻译：蓝色铁六氰基铁酸盐-III颜料（I）通过金属铁在氰化氢中的阳极氧化或含有氰化氢的反应介质在pH <7和阳极电位为<0. = 0.76V（相对于标准氢测量电极）复合到铁-II六氰基铁酸盐-II化合物（II）中，然后以常规方式将其氧化成（I）。（II）的氧化有利地在空气或氧气中在pH 0-4和70至95℃下进行，但也可以在pH> 8下进行。该方法提供易于分散的颜料（I），其具有高的着色强度并且产生明亮的光泽着色。

摘要： Aminonitriles are prepared by reacting a nitrogen compound with formaldehyde and hydrogen cyanide in the presence of an additional acid at a pH below 2 and at from 10.degree. to 70.degree. C., the concentration of the hydrogen cyanide during the reaction being not more than 3 per cent by weight, based on the reaction mixture.The aminoacetonitriles obtained by the novel process are valuable starting materials for the preparation of dyes, fungicides, bactericides, textile assistants, rubber additives, and auxiliaries used in water softening, cosmetics, the photographic industry, the paper industry and the electroplating industry.
