SOLVENT BLACK 7(CAS: 8005-02-5)

C.I. Solvent Black 7 (CAS: 8005-02-5) is a deep black dye with a crystalline form. It has a high molecular weight and excellent light and heat stability. It is slightly soluble in water but highly soluble in organic solvents. The dye is chemically stable and shows minimal reactivity under normal conditions. It is often used in textile and ink manufacturing for its deep black color and high chroma.

C.I. Solvent Black 7 (CAS: 8005-02-5) is synthesized through a multi-step process involving the coupling of aniline with 2-naphthol. This reaction typically occurs in the presence of acids as catalysts, leading to a high yield of the target compound. The process is selective and efficient, making it a common method for producing this dye.

C.I. Solvent Black 7 (CAS: 8005-02-5) is widely used in the textile and printing industries for dyeing fabrics and inks. It is also employed in the paper and leather industries for coloring various substrates. Additionally, it finds applications in colorants for plastics and other polymer-based products due to its excellent color stability and durability.

When handling C.I. Solvent Black 7 (CAS: 8005-02-5), it is crucial to wear appropriate personal protective equipment (PPE) such as gloves, goggles, and a lab coat. It should be stored in a cool, dry place away from direct sunlight and heat sources. In case of a spill, it should be cleaned up with care, using suitable absorbents, and disposing of according to local regulations. Always refer to the safety data sheet (SDS) for detailed handling instructions.
