A New and Convenient Process for Separation of Carbon Monoxide

Article abstract of DOI:10.1246/cl.1990.1873

A new method for the efficient separation of carbon monoxide from a binary mixture of carbon monoxide and hydrogen has been established by use of a selenium/secondary amine reaction system.This system consists of the selective uptake of carbon monoxide by the reaction with selenium and secondary amines to form the corresponding ammonium carbamoselenoates (1) in solution and the release of carbon monoxide by thermolysis of 1 into starting components.The amount of separated carbon monoxide was stoichiometric and the purity was higher than 99.9percent.
