Abstract

23,385. Salpetersõure Industrie-Ges. Nov. 2, 1907, [date applied for under Section 91 of Patents &c. Act, 1907]. Nitric acid.-In the process described in Specificction No. 7871, A.D. 1906, pure nitric acid is obtained by adding water or water-vapour to nitrogenous gases having a minimum temperature of 200‹ C. and cooling the mixture According to the present invention, the mixture is artificially cooled to temperatures below 0‹ C., whereby a concentrated acid is separated.
