Abstract
1454697 Pentitols from pentose rich hydrolysates SHOMEN SOKERI OSAKEYHTIO 18 April 1974 [25 April 1973] 16912/74 Heading C2C Polyols are obtained from pentose-rich pentosan hydrolysate solutions by filtering off suspended solids, removing inorganic salts and a major part of the organic impurities by ion exclusion; removing the remaining organic impurities with an ion exchange resin or activated carbon; fractionating the solution by ionexchange chromatography to give a pentose solution having a high xylose content; hydrogenating the solution to form a polyol solution; and fractionating the latter to give highly pure polyol fractions, free of unreduced sugars and other impurities. The final step of the process is preferably carried out by supplying the polyol solution to polystyrene sulphonatedivinylbenzene resin in a salt form and successively separating an unhydrogenated sugar fraction containing other impurities and a substantially pure polyol fraction.
