| titleOfInvention | Method of producing silica modified with ether of phosphonic acid |
| abstract | The invention makes it possible to simplify the method for producing phosphorus-containing chemically modified silicas and to increase the uniformity of fixed groups. Silica with aminopropyl groups is treated in a non-aqueous solvent with ketone or aldehyde and phosphorous ester at 55-65 ° C for 2-10 hours. The best results are obtained with an equimolar ratio of the reactants and grafted aminopropyl groups. |
