Abstract
Pure poly-galacturonic acid is prepd directly from agricultural by-and waste-prods contg pectin. These prods are treated in aq. medium with alkali-hydroxide,-hydrogen-carbonate and/or carbonate in the presence of catalytic concn. of alkaline-earth ions and an oxidising agent, between ambient and 90deg.C. temp. Then the liq. phase is sepd. and polygalacturonic acid is pptd by an acid. - Conversely alkaline earth ions are added to the liq. phase to obtain pptd galacturonic acid-alkali-earth-salts. These are sepd, washed with water and in opt presence of oxidising agent converted to poly-uronic acid by an acid in aq. sol
