ABSTRACT:
A process for removing acrolein from a gaseous or liquid mixture, in one case aqueous solutions, involving contacting the mixture with a compound selected from the group consisting of sodium hypochlorite; an acid salt of hydroxylamine; a urea compound such as urea itself or thiourea; sodium bisulfite and 4,4-dimethyl-1-oxa-3-azacyclopentane in an amount effective to substantially remove acrolein has been discovered. The process works particularly well in selectively scavenging acrolein from aqueous solutions containing acrylonitrile.
