Pigment Blue 16 (CI 74100) is a chemical compound, a synthetic dye with Phthalocyanine (an aromatic macrocyclic compound related to porphyrins with an intense blue-green colour.) and is known as Phthalocyanine

Chemical Name

29H,31H-Phthalocyanine

Chemical Industrial Synthesis Process

Preparation of reagents. The main raw materials include phthalonitrile, copper (or another central metal), and solvents such as dimethylformamide (DMF).
Synthesis of phthalocyanine intermediate. The production of CI 74100 begins with the cyclization of phthalonitrile in the presence of copper and solvents under high-temperature conditions, forming the copper phthalocyanine complex.
Chlorination. The phthalocyanine complex is treated with chlorine to introduce chlorine groups into the molecular structure, enhancing the coloring properties.
Purification. The crude CI 74100 product is purified using techniques such as crystallization, filtration, and chromatography to remove impurities and achieve a high-purity colorant.
Stabilization. The purified CI 74100 is stabilized to ensure its stability during transportation and storage, preventing degradation and oxidation.
Drying. The purified product is dried at controlled temperatures to obtain a fine powder.
Quality control. The CI 74100 undergoes rigorous quality testing to ensure it meets standards for purity, color intensity, and safety. These tests include chemical analysis, spectroscopy, and microbiological testing.
