Heavy nitrogen is of importance for homogeneous breeder reactors in case it could be produced cheaply enough in commercial quantitites. The rectification of nitric oxide may be the most profitable process from the energy standpoint of the methods proposed. It is reversible and shows a large elementary separation effect, which is only exceeded by the chemical NO--HNO/sub 3/ method. But there is the disadvantage that it must be coupled with the production or sulfuric acid from pure sulfur dioxide. In the NO rectification undesired byproducts are missing, whereas the possibility of obtaining simultaneously the heavy oxygen isotopes O/sup 17/ and O/sup 18/ is welcome. The rectification method with glass columns of special construction is described, and the expected results were obtained. In a 10 mm wide column a height equivalent theoretical plate (HETP) of 10 cm was obtained. Because of the large separation factor a column length of 31 cm is sufficient at an operating pressure of 200 mm Ag for the displacement of both isotopes by the factor e.
