EN 4134 "IMPROVED PROCEDURE FOR THE REMOVAL OF CATALYTIC RESIDUES BASED ON AlCl3 AND/OR ITS COMPLEX COMPOUNDS" Abstract A selective procedure is described for the removal of catalytic residues based on AlCl3 or its complex compounds deriving from the (co) polymerization of olefinic and diolefinic cuts, allowing the production of almost colourless hydrocarbon resins. This procedure involves putting the polymerized mass in contact with organometallic compounds, treating the resulting mixture with water or aqueous solutions, either acidic or basic, and separating the organic phase, which at this point is without inorganic residues.
