| titleOfInvention | Cellulose ether-based gel-forming composition and methods of use and preparation thereof |
| abstract | ABSTRACT OF THE DISCLOSURE The application discloses a gel-forming com-position based on a) water, b) a water-soluble cellulose mixed ether having at least one nonionic substituent from the group comprising hydroxyalkyl and alkyl and at least one anionic phosphorus-containing substituent, and c) a salt containing a cation which is at least divalent. The phosphorus-containing substituent is a phosphonoalkyl group or a P-alkylphosphinoalkyl group. The application also relates to a process for the preparation of a gel from this composition, to the reversible reversing of the gel by the addition of an agent which complexes the cation, e.g. in the case of Al3+ ions, Fe3+ ions, Zr4+ ions or ZrO2+ ions, by means of an amount of fluoride ions, and to the use of this gel-forming composition in the secondary production of petroleum. |
