Procedure

100 g (0.33 mole) of sodium hexyl α-D-galactopyranoside uronate prepared according to Example 11 are solubilized in water (15% solution). After acidification to pH=2, concentrating under vacuum and selectively precipitating the salts in acetone, hexyl α-D-galactopyranoside uronic acid, whose physicochemical characteristics are indicated below, is recovered with a 95% yield:
