Radiation-induced chemical reactions of carbon monoxide and hydrogen mixture—III. Solid materials produced under irradiation

Abstract

Three varieties of nonvolatile solid products A, B, and C were obtained from the CO-H 2 mixtures irradiated by electron beam in different conditions. Solids A and B were obtained as a deposit on the wall of reaction vessel from the mixture containing 15 and 78 mol % CO, respectively. The solid C was obtained as the deposit in the cold traps set in the path of reactant (15 mol% CO) circulation. From the analyses by IR, GC, and mass spectrometer and characteristics of these solids, it was suggested that the solid A was the substance formed from the reaction of HCHO with carboxylic acid, the solid B was C 3O 2 polymer having low molecular weight, and the solid C was paraformaldehyde.
