Phthalonitrile → Dichlorotitanium phthalocyanine

Participants

Reaction Conditions

Reaction Steps

In 100 g of α-chloronaphthalene, 5.0 g of o-phthalodinitrile and 2.0 g of titanium tetrachloride were mixed, and heated and stirred at 200° C. for 3 hours. Then the mixture was cooled to 50° C. The deposited crystals were collected by filtration to obtain pasty dichlorotitanium phthalocyanine. This paste was washed by agitation in 100 ml of N,N'-dimethylformamide at 100° C. Further the paste was washed twice with methanol at 60° C., and collected by filtration. The paste was further agitated in 100 ml of deionized water at 80° C. for one hour, and collected again by filtration to obtain 4.3 g of crystalline oxytitanium phthalocyanine in blue color. The results of the elemental analysis of the resulting compound were as follows.
