Two-stage IRMPD process for practical 13C enrichment. CHClF2/Br2 mixtures

Abstract

The CO2-laser-induced IRMPD of CHClF2/Br2 mixtures produced CBr2F2 as a main product, which was considerably enriched with 13C under selected irradiation conditions. Further IRMPD of CBr2F2 in the presence of O2 gave CF2O at a 13C-atom fraction as high as 86%. The CF2O was converted to 13#C-enriched CO2 via hydrolysis. © 1988.
