Crystal and molecularstructures of four derivatives of D-mannose are described. Each could exist as either an open-chain Schiff base or as a glycosylamine in the solid state. The derivative formed upon reaction of D-mannose with hydroxylamine is an open-chain oxime, but those formed upon reaction with semicarbazide, aniline, and p-chloroaniline are glycosylamines. The oxime, which crystallizes as
The invention relates to a chromatographic separation process of recovering mannose with high purity. The invention is based on the use of a chromatographic separation resin including a resin which is at least partly in a Ba
