Beschreibung

C.I.Direct Black 32 is a diazonium salt with an average particle diameter of about 10 nm and a dichroic ratio of about 1.5. It is used in the manufacture of organic colorants, such as black, brown, blue, and green pigments. C.I.Direct Black 32 has been used as a model species to study the chemical reaction rate of small particles in solution and the kinetics of thermal decomposition of intramolecular hydrogen bonds in polyphenols at various temperatures. The material can be recycled by dissolving it in an organic solvent and precipitating it out with water or uv irradiation.br>
C.I.Direct Black 32 has strong absorption properties in the ultraviolet region (UV) and is used for coloring plastics, paper products, textiles, printing ink, leathers, etc.br>
