Abstract

1,179,648. Removing carbonyl compound impurities. MONSANTO CO. 7 Aug., 1968 [7 Aug., 1967; 8 Aug., 1967], No. 37641/68. Heading C2C. [Also in Division C3] An organic carbonyl compound is removed from a fluid stream in which it exists as an impurity by passing said stream through a bed of a weak-acid ion-exchange resin, which resin has at least some of its functional groups converted to the salt of a compound selected from hydrazine, monosubstituted hydrazine, unsymmetrically disubstituted hydrazine, hydroxylamine and O-substituted hydroxylamine. The fluid stream may be of an organic compound containing at least one hydroxyl group contaminated with aldehydes and ketones. In the examples isobutyraldehyde and methyl ethyl ketone are removed from a methanol stream by passing the stream through a bed of cross-linked acrylic acid resin which has been treated with hydrazine, or of methacrylic acid-divinyl benzene resin which has been treated with hydroxylamine.
