Zusammenfassung:AlCl3 is recovered from a mixt. of gaseous chlorides by contacting the mixt. at 70-250 degrees with a solvent in which AlCl3 is soluble, to dissolve it and subsequently separating the AlCl3 from the soln. The solvent pref. has a fusion point is not >200 degrees C and a b.pt. >250 degrees C. Used for prodn. of AlCl3 as one stage in the prodn. of AlCl3 catalyst, metallic Al or Al2O3 pigments or as nucleating agent for colouring TiO2 pigments.
