Claims
- 1. A process for cleaving precipitated fatty amine adducts of microbial polysaccharides containing a carboxy or ester group(s) and for isolating the free microbial polysaccharides containing a carboxy or ester group(s) from said fatty amine adducts, which comprises treating said adducts with at least an equimolar amount of a salt of ammonia or of a highly volatile amine in the presence of an alcohol in which said salt is soluble or readily thermally dissociated.
- 2. The process as claimed in claim 1, wherein the alcohol has a boiling point under atmospheric pressure of up to about 100.degree. C.
- 3. The process as claimed in claim 1, wherein the alcohol is a lower alkanol.
- 4. The process as claimed in claim 1, wherein the highly volatile amine has a boiling point under atmospheric pressure of less than 150.degree. C.
- 5. The process as claimed in claim 1, wherein the reaction is carried out at the reflux temperature of the reaction mixture.
- 6. The process as claimed in claim 1, wherein the microbial polysaccharide is xanthan.
- 7. The process as claimed in claim 1, wherein the fatty amine is a primary fatty alkylamine.
- 8. The process as claimed in claim 1, wherein the fatty amine is a tertiary fatty alkylamine which has two short-chain alkyl radicals.
- 9. A process for cleaving a precipitated fatty amine adduct of a xanthan polysaccharide and for isolating the free xanthan polysaccharide from said fatty amine adduct, which comprises treating said adduct with a salt of ammonia or of a highly volatile amine capable of cleaving said free xanthan polysaccharide from said fatty amine adduct in the presence of a lower alkanol in which said salt is soluble or readily thermally dissociated.
