METHOD OF PRODUCING HYDROPHOBIC ALUMINOSILICATE ADSORBENT Russian patent published in 2012 - IPC B01J20/16 B01J20/22 B01J20/30

Abstract RU 2462304 C1

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing hydrophobic adsorbents from natural aluminosilicates. The adsorbent is obtained by treating kaolinite or montmorillonite with particle size less than 0.16 mm with a solution of organosiloxane liquids in toluene of concentration 0.98-3.96 mol/l while heating to temperature 98-100°C for 2-8 hours. The organosiloxane liquids used are hexamethyldisiloxane, octamethyltetrasiloxane and methylphenylcyclotrisiloxane.

EFFECT: obtaining selective hydrophobic adsorbents.
