실험 절차

Titanium tetrachloride (18 g) and phthalodinitrile (40 g) were agitated in α-chloronaphthalene (500 ml) at 240°-250° C. under a nitrogen stream. After completion of the reaction, the product dichlorotitanium phthalocyanine was recovered by filtration. The recovered dichlorotitanium phthalocyanine was heated under reflux for 1 hour together with concentrated aqueous ammonia (300 ml) and pyridine (300 ml) so as to obtain the end compound, α-type titanyl phthalocyanine (18 g). This compound was thoroughly washed in a Soxhlet extractor first with N,N-dimethylformamide, then with acetone.
