The numerous, chemical reactions (hydrolysis, cracking, hydrogenation), occurring during the catalytic hydrogenolysis of saccharides, result in a ulticomponent mixture, consisting mainly of polyhydric alcohols. These alcohols, in general, have high boiling points and a poor thermostability. Separation of the individual components by high-vacuum distillation requires a relatively high temperature that causes dehydration, condensation, and charring. Qualitative paper chromatographic and quantitative gas-liquid chromatographic methods of analysis have therefore been developed; these provide useful tools for further studies on reaction mechanisms and reaction kinetics of the hydrogenolysis of saccharides.
