Phthalocyanine blue (copper) has broad application prospects. In the future, local companies need to increase technology research and development efforts.

Phthalocyanine blue, also known as copper phthalocyanine and copper titanium cyanine, is an organic substance with the chemical formula C32H16CuN8. It appears as bright green light blue rod-shaped crystals. It is flammable and insoluble in water, alcohol and hydrocarbons. It dissolves in concentrated sulfuric acid and becomes olive. Color solution, after dilution, a blue suspension precipitates. Phthalocyanine blue is a typical phthalocyanine organic pigment. According to different crystal forms, it can be divided into α-type, β-type, γ-type, δ-type, ε-type phthalocyanine blue, etc.; according to different properties, it can be divided into Unstable type, anti-crystallization type, anti-flocculation type phthalocyanine blue, etc.

There are various production methods for phthalocyanine blue, which mainly include the phthalonitrile baking method, which refers to the method of using phthalonitrile and cuprous chloride as raw materials to produce phthalocyanine blue through mixing, heating, exothermic reaction, cooling and other links; The phthalonitrile solvent method refers to a method that uses phthalonitrile, catalyst, copper salt (cuprous chloride or copper chloride) as raw materials, adds them to an ammonia saturated solvent and heats them to generate phthalocyanine blue ; The phthalic anhydride-urea method refers to a method that uses phthalic anhydride, cuprous chloride, ammonium trimolybdate, urea, etc. as raw materials, and produces phthalocyanine blue through even mixing, heating, cooling, etc. Among them, the phthalic anhydride-urea method has cheap and easy raw materials and low production cost, and is currently the mainstream method for industrial production of phthalocyanine blue.

According to the “2023-2028 Phthalocyanine Blue (Copper) Industry Market In-depth Research and Investment Prospect Forecast Analysis Report” released by the Industrial Research Center Show that as an important type of organic pigment, phthalocyanine blue has the advantages of bright color, strong tinting power, good environmental protection, good solvent resistance, strong acid and alkali resistance, good heat resistance, etc., and can be widely used in inks, The coloring scene of paint, printing, rubber, plastic and other products has broad market development space. The global phthalocyanine blue market size will be approximately US$2.41 billion in 2022, a year-on-year growth of approximately 5.5%.

At the same time, as research becomes more in-depth, the application fields of phthalocyanine blue are constantly expanding, and it also has high application prospects in electronics, LED displays, photovoltaic cells and other fields. Specifically, in the field of photovoltaics, phthalocyanine blue has a photovoltaic effect and can be used to manufacture stable and cheap solar cells; in the field of electronics, phthalocyanine blue can be used to manufacture electronic devices such as gas sensors due to its gas sensitivity, and can also be used to Produce electronic materials such as photoresist and sensitizer; in the field of LED display, phthalocyanine blue can be used in liquid crystal light valve manufacturing scenarios due to its photoconductivity.

Industry analysts said that the phthalocyanine blue industry shows good development prospects, and there are currently many domestic and foreign Manufacturers in this field mainly include internationally renowned chemical manufacturers such as BASF of Germany and Dow Chemical of the United States, as well as Anhui Shenlanhua Color Materials, Shuangle Pigment Co., Ltd., Liaoning Senyuan Chemical, Yancheng Fengze Chemical, Shandong Hualan Chemical, Nantong Asia-Pacific Pigments, Jiangsu Chinese manufacturers such as Yongyue New Materials. Due to technical limitations, domestic phthalocyanine blue is mostly a pigment product used in ink and paint coloring scenarios. In the future, local companies will need to continue to increase technology research and development and promote the continuous optimization of product structures, thereby promoting high-performance products used in electronics, photovoltaics and other fields. Phthalocyanine blue production continues to increase.
