Phthalonitrile → Phthalocyanine

Participants

Reaction Steps

78.2 mmoles of phthalonitrile and 15.8 mmoles of a trihalogenometal are added to 100 ml of quinoline purified by distillation twice. The mixture is heated under reflux for 0.5 to 3 hours and cooled to room temperature, and the reaction product is filtered. The solid product is washed with successive, toluene, acetone and methanol, and then with methanol by using a Soxhlet's extractor. The washed product is dried in vacuo at 60° C., to obtain a monohalogenometal phthalocyanine.
