In this study, a power variable microwave synthetic system has been developed with modifying domestic microwave oven. The results of synthesis between phthalic anhydride and urea in copper I chloride for about 0.5~4h at about 155~170℃ under conventional and microwave synthethic method led to an copper phthalocyanine in higher yield and purity under microwave synthetic method, compare to conventional one. The morphologies of the samples synthesized at various reaction condition underthe conventional thermal and microwave method have been characterized by the means of SEM and BET.
