• For the manufacture of sodium hydroxide and nitric acid a new thermochemical process of splitting sodium nitrate has been proposed which consists of (i) splitting of sodium nitrate by iron(III) oxide, (ii) hydrolysis of sodium ferrate, and (iii) absorption of nitrogen dioxide into water. Key reactions (i) and (ii) have experimentally been verified. The overall heat requirement for the process is discussed on the basis of a material and heat flow-sheet of the process constructed.
