ABSTRACT:
The invention relates to a method for the preparation of rhamnose from rhamnolipids, for which an acidic emulsion of the rhamnolipid is hydrolyzed at 100.degree. to 200.degree. and subsequently cooled, the aqueous phase of the resulting hydrolysate is separated from the lipid phase, its pH is raised by the addition of a basic compound, any precipitate formed is removed, the remaining solution is concentrated and either processed further directly or chromatographed on ion exchange resin, rhamnose-containing fractions being obtained as eluate, which are processed further as such or worked up into crystalline rhamnose monohydrate.
