Abstract: 1,159,399. Nitric oxide. BADISCHE ANILIN- & SODA-FABRIK A.G. 2 Dec., 1966 [4 Dec., 1965]. No. 54079/66. Heading C1A. Nitric oxide is produced by reacting sulphur with aqueous nitric acid at an HNO 3 ; S molar ratio of at least 4 : 3 in a reactor at 350- 650‹ C. The sulphur may be supplied to the reactor in vapour or liquid form, in the latter case by spraying, and the nitric acid in vapour form. The nitric acid used may have a concentration of 30-70 wt. per cent. At an HNO 3 : S molar ratio of 4 : 3 the principal by-product is SO 2 , and at 6 : 3 or more it is H 2 SO 4 . In the latter case, nitric oxide of 99% purity and pure dilute sulphuric acid may be obtained by passing the hot reaction gases to a distillation column, separately condensing out the sulphuric acid and any excess nitric acid present, and freeing the NO from other nitrogen oxides by washing with e.g. caustic soda solution.
