Abstract: FOR THE SEPARATION OF BROMINE FROM GASEOUS MIXTURES WHICH, IN ADDITION TO BROMINE, CONTAIN OXIDES OF NITROGEN WITH LESS THAN PENTAVALENT NITROGEN AND WITH OR WITHOUT NITROSYL BROMIDE, AT LEAST AS MUCH OXYGEN IS ADDED AS IS NECESSARY FOR CONVERTING THE NITROGEN OF THE OXIDES OR NITROSYL BROMIDE INTO THE PENTRVALENT STATE. THESE MIXTURES ARE THEN TREATED WITH WATER OR DILUTE AQUEOUS NITRIC ACID.

Abstract: Recovery of pure 1,4-dicyanobutenes from 1,4-dicyanobutenes containing halogen, particularly chlorine or bromine, by treatment with a hexamethylenediamine or with dihexamethylenetriamine in the liquid phase and separation of the 1,4-dicyanobutenes from the reaction products of the added hexamethylenediamine with the halogen compound.
