FIELD: domestic chemistry; production of cat litters. ^ SUBSTANCE: cat litter is made from silica gel which is obtained from wastes of ethanol process by ethylene hydration. Method of production of litter includes the following operations: sifting-off dust-like fraction at grain diameter lesser that 0.5 mm, activating the working fraction no less than 0.5 mm at temperature of 120-150°C continued for 3-5 h. ^ EFFECT: increased moisture capacity; low cost of filler. ^ 3 cl, 1 tbl, 1 ex |
