Abstract
In the production of a fertilizing material according to the parent Specification, by oxidizing vegetable fuels such as peat, coal, anthracite, or lignite with nitric acid at low temperatures, for example, from 50-90 DEG C. in the presence of a substantial quantity of water, and boiling the reaction product until the greater part is soluble in alkali, the nitrogen oxides evolved during the oxidation being reconverted into nitric acid to be used again, the nitric acid for the oxidation is produced in situ by means of a reaction mixture, which may comprise a nitrate such as sodium nitrate and a mineral acid such as sulphuric acid, some or all of which latter may be replaced by nitre-cake. Nitric acid is produced advantageously by this method, since the sulphuric acid, which may be used in the form of dilute solutions such as spent nitrating acids and the like, is almost completely utilized, and also because the temperatures employed are moderate. Examples are given.ALSO:In the production of a fertilizing-material according to the parent Specification by oxidizing vegetable fuels such as peat, coal, anthracite, or lignite with nitric acid at low temperatures, for example, from 50 to 90 DEG C., in the presence of a substantial quantity of water, and boiling the reaction product until the greater part is soluble in alkali, the nitrogen oxides evolved during the oxidation being reconverted into nitric acid to be used again, the nitric acid for the oxidation is produced in situ by means of a reaction mixture, which may comprise a nitrate such as sodium nitrate and a mineral acid such as sulphuric acid, some or all of which latter may be replaced by nitrecake.
