FIELD: sorbents. ^ SUBSTANCE: invention relates to synthesis of organosilicon adsorbent, which can be used in a variety of national economy fields (chemistry, pharmaceutics, public health). Proposed adsorbent is nonlinear condensation product depicted by formula wherein n=88-98. Preparation procedure comprises reaction of 19-20 parts of alkali solution of sodium dihydroxymethylsilicate, density 1.16-1.19 g/cc, with 6 parts of sulfuric acid, density 1.195-1.205 g/cc, while stirring at 0-5 C until ripening of desired product is completed, after which product divided into small pieces and washed. ^ EFFECT: increased assortment of various-destination adsorbents. ^ 2 cl, 3 dwg, 5 tbl, 3 ex |
