The action of barium hydroxide on certain of the monobasic sugar acids
Abstract
In spite of the great amount of work of a semi-quantitative nature done by different investigators in the last thirty years on the action of alkalis upon sugars, very little has been done to determine the effect of alkalis upon the corresponding sugar acids, and many times it was tacitly assumed that the acids would be relatively stable if they were formed during the degradation of sugars with alkalis.When he found that some of the organic bases would cause the hydrogen and hydroxyl radicals on the alpha carbon atom, of the acid to be interchanged, Fischer1 was the first to note the effect of alkalis upon the sugar acids. The first study of the action of metallic hydroxides was made by X ef,2 who found that glyceric acid gave carbonic, formic, oxalic, and lactic acids when heated to a temperature of 150-220° C. with sodium hydroxide. Xo further reference is found in the literature in which the action of metallic hydroxides on sugar acids has been reported until 1933 when Bonnett and Upson3 showed that barium hydroxide could be used to bring about the epimeric change, a result observed previously only in the presence of organic bases.
