METHOD FOR PRODUCING BASIC ALUMINIUM CHLORIDES

摘要

The invention relates to producing basic aluminium chlorides which can be used for different industries. The inventive method consists in loading an aqueous hydrochloric acid solution in a reactor, in adding a catalyst and aluminium batches, in carrying out interreaction thereof at a temperature ranging from 60 to 110 DEG C, in adding a stabiliser into reaction mixture after introducing at least 60 % of aluminium, in adding a polymeriser to the thus obtained product and stirring it after the total aluminium reaction, in cooling and discharging said mixture and in obtaining a final product by means of the increased molecular mass. The catalyst is embodied in the form of organic compounds containing a methyl group, for example trimethylene-glycol and/or hexymethylene tetramine and/or decyl aldehyde. The polymeriser is embodied in the form of the mixture of monocarboxylic acid and sodium carbonate in the quantity of 0.5-2 % with respect to the final product mass. The stabiliser is embodied in the form of the mixture of aldohexose with a citric acid in a quantity of 0.5-1.5 % with respect to the final product. Said method makes it possible to reduce the time for producing an inorganic polymer and to increase the stability of the structure thereof.
