| titleOfInvention | Method for production of hydrophobic magnetic sorbent |
| abstract | In the process for producing a hydrophobic magnetic sorbent, a mixture of 180 to 220 parts by weight of water glass with 900 to 1200 parts by weight of water is precipitated with an acid having a concentration of 20 to 50% by weight. to pH 4.9 to 5.1. The resulting silica gel is washed with water, then 30 to 70% by weight is evaporated. of water, then 1 to 3 parts by weight of magnetite and 1 to 3 parts by weight of an aqueous solution containing 20 to 30% by weight of water are added. tetramethylammonium hydroxide per 100 parts by weight of washed silica gel before evaporation. The resulting mixture is extruded, 30 to 75 parts by weight of water are evaporated from the extrudates by drying at 40 to 80 ° C and then silanized in 80 to 120 parts by weight of methanol containing 0.5 to 1.5% by weight. silane at 60-65 ° C for 3 to 6 hours, after which the extrudates are filtered off and then the methanol is evaporated at 40-70 ° C. |
