Title: Improvements in the manufacture and production of metal oxides colloidally soluble in water
IPC: B01J13/00
Filed: 1934-07-16
Abstract: Hydroxides of trivalent metals, e.g. iron or chromium but particularly aluminium, colloidally soluble in water, or colloidal solutions thereof, are obtained by treating the metal salts with dissolved, liquid or gaseous ammonia or other nitrogen compounds suitable for the formation of hydroxides in an amount greater or less than the stoichiometrical proportion and then subjecting the product, preferably after separation of the mother liquor, to a protective drying, e.g. from 80--120 DEG  C. before or during peptisation with acid, e.g. with 10 per cent of the stoichiometrical proportion of hydrochloric acid.  Suitable p  bases, other than ammonia, include ammonium sulphides, ammonium carbonates, ammonium carbamate, carbamic acid, urea, pyridine or aniline, and they may be used in excess, e.g. 50 per cent or more or in a definiciey of up to 10 per cent.  The reaction mass may be subjected to a protective drying before soluble salts are washed from the mass, and may in addition be protectively dried during the peptisation step.  The mother liquor may first be separated from the reaction mass, which is then dried and stirred with the mother liquor.  A further separation into mother liquor and residue is effected and the residue washed thoroughly with a little water and dried if desired to a content of 65--75 per cent Al2O3 and then peptised, the mass being protectively dried before or after, but preferably during the peptisation.  For example, solid crystalline aluminium nitrate, if desired free from iron, may be treated in a closed vessel with liquid or gaseous ammonia, extracted with liquid ammonia and the ammonia remaining in the alumina removed by moderate heating or by steam. Peptisation with simultaneous protective drying gives nearly a quantitative yield of water-soluble alumina. According to an example, 2000 kgm. of aluminium nitrate solution containing 4,71 per cent by weight of aluminium and 7,16 per cent of nitrogen are ground in a ball mill for an hour with 1375 kgm. of 18,98 per cent aqueous ammonia, i.e. 150 per cent of the stoichiometrical amount.  The mass is filtered and the cake dried at 80--100 DEG  C., the vapours being recovered, and then stirred with the filtrate.  The mass is again filtered and the cake washed with a little ammonia and then with small quantities of very dilute aqueous ammonia, the wash water being added to the condensate and mother liquor, 97--98 per cent of the total nitrogen being recovered, as ammonium nitrate.  The precipitate, containing 272 kgm. of Al(OH)3 and the residual ammonium nitrate, is kneaded with 50 kgm. of 38 per cent hydrochloric acid, 53 kgm. of 62 per cent nitric acid or 31 kgm. of glacial acetic acid and forms a colloidal solution, which may be clarified by centrifuging with a collodion filter.  By protective drying, e.g. by spraying, gels with a content of 70 per cent Al2O3 may be obtained which are soluble with swelling in cold water.  The products may be used for the purposes detailed in Specification 441,384.
