Abstract
283,117. Buchner, M. Jan. 3, 1927,- [Convention date]. Nitric acid. - The decomposition by heat of aluminium nitrate is effected in vacuo with addition of water or steam, whereby the yield of nitric acid is increased. By working, for instance, at an absolute pressure of 220 mms. 75 per cent of the nitric acid may be obtained at 145‹ C. and up to 92 per cent at 200‹ C. Basic aluminium nitrate is preferably employed. By controlling the addition of water or steam during the heat treatment nitric acid of a given concentration may be obtained.
