Dinitrogen trioxide. Part VII. The absorption of nitric oxide by dinitrogen tetroxide and the preparation of pure dinitrogen trioxide

Abstract

The absorption of NO by liquid and solid N₂O₄ has been studied. For the liquid, the amount of N₂O₃ that can be obtained at any temperature is less than the equilibrium concentration. The rapid reaction with the solid suggests that NO and N₂O₄ are capable of direct reaction. The various methods for the preparation of N₂O₃ are critically examined.
