Description
Известны различные способы получени роданида железа закисного, в частности способы, основанные на взаимодействии ионов CNS7 например обменным разлол ением роданида бари и сульфата железа закисного, а также обменным разложением солей закисного железа и роданистоводородной кислоты. Указанные способы не обеспечивают получени чистого продукта.Various methods are known for the preparation of ferrous ferric rhodanide, in particular, methods based on the interaction of CNS7 ions, for example, by the exchange splitting of barium rhodanide and ferrous ferrous sulfate, as well as by the exchange decomposition of ferrous ferrous salts and hydro genic acid. These methods do not provide a pure product.
Предлагаемый способ получени роданида железа закиспого отличаетс тем, что роданид железа закиспого получают взаимодействием роданида свинца и сульфата железа закнсиого.The proposed method for producing ferric iron rhodanide is characterized in that iron rhodanide is produced by the interaction of lead rhodanide and iron sulfate.
Описываемый снособ позвол ет получать более чистый продукт в сравпепии с другими способами получени роданида железа закисного.The described method allows the production of a cleaner product in comparison with other methods for producing ferrous iron rhodanide.
Пример. В сосуд емкостью 5 л загружают 2,9 кг железного купороса , 3 кг роданида свинца и добавл ют 1,5 л воды. Реагируюш,ую смесь подогревают нрн тш.ательном перемешивании до полного исчезновени.ч кристаллического л елезного купороса . Полученный раствор роданида лселеза фильтрацией отдел ют от осадка с целью осаждени сульфатов , смешивают с 30 г карбоната бари при нагревании. Раствор, освобожденный от сульфат-ионов, отфильтровывают и упаривают при 80.Example. In a vessel with a capacity of 5 liters, 2.9 kg of iron sulphate, 3 kg of lead rhodanide are added and 1.5 liters of water are added. The reactive mixture is heated by mixing stirring until complete disappearance of the crystalline vitriol. The resulting solution of rhodanide elseza is separated by filtration from the precipitate to precipitate the sulphates, mixed with 30 g of barium carbonate with heating. The solution, freed from sulfate ions, is filtered off and evaporated at 80.
