Phthalocyanine blue B was produced by ammonolysis reaction, substitution reaction, complexation reaction and condensation reaction using phthalic anhydride, urea and cuprous chloride as raw materials. The morphology of the intermediate and the product were observed by metallurgical microscope, and the structure of the functional group and the characteristic peaks of analytical spectrum were characterized by IR and UV-visible spectroscopy, and the optical stability of the product was investigated. Through this experiment, different chemical unit operations are brought together into a knowledge chain, and different types of reactions ware integrated to achieve the goal of inspiring innovation consciousness, improving comprehensive knowledge and practical skills.

Key words: Phthalocyanine blue, Comprehensive, Experimental teaching, Spectrum, Degradation rate
