Preparation method for phthalocyanine compound

The invention discloses a preparation method for phthalocyanine compound. The preparation method for phthalocyanine compound comprises the following steps: firstly, adding raw materials of phthalic anhydride or derivative thereof, metallic compound, and carbamide into a cone-shaped bottle in a mixed manner, and adding 2wt% para-toluenesulfonic acid compound as catalyst; sealing the opening of the bottle, placing the bottle into an oil bath pan to heat and fuse, stirring for 10 minutes under 80-125 DEG C, and enabling the raw materials to uniformly mix; further placing in a domestic microwave oven to heat for 2-5 minutes in high power, using a glass rod to uniformly stir, and further placing in the domestic microwave oven to heat in low power, pouring into deionized water after using concentrated sulfuric acid to dissolve acquired products, using a vacuum pump to filter, using 10% sodium hydroxide (NaOH) solution to wash the products to a state that potential of hydrogen (pH) is equal to 7, and further using d
