Phthalonitrile → Dichlorotitanium phthalocyanine

Participants

Reaction Conditions

Reaction Steps

40 g of o-phthalodinitrile, 18 g of titanium tetrachloride and 500 ml of α-chloronaphthalene were heated at 200 to 250° C. with stirring in a nitrogen atmosphere for 3 hours to react. Then, the reaction mixture was allowed to cool to 100 to 130° C. and filtered under heating and the residue was washed with α-chloronaphthalene heated to 100° C. to obtain a crude product of dichlorotitanium-phthalocyanine.
