摘要：

以邻苯二甲酸酐、尿素、氯化亚铜为原料经氨解、取代、络合、缩合反应生成酞菁蓝B，通过镜像显微镜观察产品的形态，红外/紫外光谱法表征官能团结构和解析谱学特征峰，并考查产品的光稳定性。通过该实验将不同化学单元操作汇集为知识链，不同类型反应融汇贯通，达到了创新意识启发、综合知识提升及实践技能提高的目的。

Abstract:

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.
