摘要:Synthesis is for an organosilicic adsorbent, which can be used in different economic sectors (chemical and pharmaceutical industries, health service). The adsorbent represents the non-linear reaction product of polycondensation, a polyhydrate of 1,1,3,3-tetrahydroxy-1,3-dimethyldisiloxane having from 88 to 89 moles of water per one mole of 1,1,3,3-tetrahydroxy-1,3-dimethyldisiloxane. n The adsorbent is produced by means of mixing 19-20 parts of alkaline solution of sodium dioximethylsiliconate (DOMS) with a density of 1.16-1.19 g/cm 3 with 6 parts of sulfuric acid with a density of 1.195-1.205 g/cm 3 at a temperature of between 0-5° C. followed by aging of the mixture, followed by addition of water, followed by mixing, followed by breaking up of the solid product resulting in a suspension, followed by the addition of more water to the suspension, then allowing the suspension to settle, followed by removal of the supernatant via decantation, followed by repetition of the settling and decanting steps until the DOMS is removed completely, whereupon the final product is washed with a solution of sulphuric acid until water wash has a pH of 4.0, then the final product is washed with purified water until water wash has a pH of 5.0-7.0 followed by drying.
