Versuchsvorschrift

As in Example 1, 22.7 g of ammonium alum and 21.8 g of 8-hydroxyquinoline were added to 150 g of water and the mixture was neutralized by dropwise addition of 6.5 g of a 33% solution of sodium hydroxide with stirring and allowed to react. The solid formed was washed with water and dried to give 21 g of Alq3. The raw material Alq3 thus prepared was refined in the metallic apparatus for refining by sublimation illustrated in FIG. 1 to give 11 g of refined Alq3.
