A METHOD FOR PURIFICATION AND MODIFICATION OF MINERAL CLAYS IN NON-AQUEOUS SOLVENTS
摘要
<p>The present invention discloses a method for obtaining organoclay from crude mineral clay, an organoclay obtainable by this method, a method for incorporating organoclay into a polymeric matrix to obtain composites, and some composites obtainable by this method. The method for obtaining organoclay includes reacting crude mineral clay with quaternary ammonium or phosphonium salt in a non-aqueous solvent to obtain ion-exchanged organoclay suspended in this solvent and a solid residue; and separating out the solid residue. The solvent is then separated, preferably by evaporation or filtration.</p>
