반응 조건

반응 단계

In 100 g of α-chloronaphthalene, 5.0 g of o-phthalodinitrile and 2.0 g of titanium tetrachloride were stirred for 3 hours at 200° C., followed by cooling to 50° C. to precipitate a crystal. The crystal was recovered by filtration to obtain a paste of dichlorotitanium phthalocyanine, followed by washing with 100 ml of N,N-dimethylformamide at 100° C. under stirring and two times of washing with 100 ml of methanol at 60° C. The resultant paste was recovered by filtration and stirred in 100 ml of deionized water for 1 hour at 80° C., followed by filtration to obtain 4.3 g of a blue oxytitanium phthalocyanine crystal. The results of elementary analysis are shown below.
