CI 74180 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 Direct Blue 86.

Chemical Name

• Disodium [29H,31H-phthalocyaninedisulphonato(4-)-N29,N30,N31,N32]cuprate(2-)

Chemical Industrial Synthesis Process

• Preparation of reagents. The main raw materials include phthalocyanine and solvents such as dimethylformamide (DMF).
• Synthesis of phthalocyanine intermediate. The production of CI 74180 begins with the cyclization of phthalocyanine in the presence of cobalt and solvents under high-temperature conditions, forming the cobalt phthalocyanine complex.
• Substitution. The phthalocyanine complex is treated with specific reagents to introduce functional groups that enhance the coloring properties and solubility of the dye.
• Purification. The crude CI 74180 product is purified using techniques such as crystallization, filtration, and chromatography to remove impurities and achieve a high-purity colorant.
• Stabilization. The purified CI 74180 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 74180 undergoes rigorous quality testing to ensure it meets standards for purity, color intensity, and safety. These tests include chemical analysis, spectroscopy, and microbiological testing.
