FAQ

What are the physical and chemical properties of Solvent Black 5 (CAS: 11099-03-9)?

Solvent Black 5 is a deep black dye with a molecular weight of approximately 1000. It exhibits good solubility in polar organic solvents such as ethanol and acetone. Chemically, it is stable under normal conditions but may lose color when exposed to strong acids or bases. It has low reactivity and is often used as a pigment in inks and paints due to its excellent light and weather resistance.

How is Solvent Black 5 (CAS: 11099-03-9) typically synthesized?

Solvent Black 5 is synthesized through a condensation polymerization of aniline and azo coupling, involving the use of catalysts like acetic anhydride. The process yields a high molecular weight polymer with good dyeing properties. The synthesis is conducted under controlled conditions to achieve high selectivity and yield, making it a viable and common method for industrial production.

What industries use Solvent Black 5 (CAS: 11099-03-9)?

Solvent Black 5 is widely used in the printing and dyeing industry, particularly for inks, paints, and varnishes. It is also found in the textile industry for dyeing and printing fabrics. Additionally, it is used in the automotive industry for paint formulations and in the construction sector for pigmented coatings. Its stability and colorfastness make it a preferred choice in these applications.

What precautions should be taken when handling Solvent Black 5 (CAS: 11099-03-9)?

When handling Solvent Black 5, it is essential to wear appropriate personal protective equipment (PPE) such as gloves, safety goggles, and a lab coat. It should be stored in a well-ventilated area away from direct sunlight and heat sources. In case of a spill, use appropriate containment materials and dispose of according to local regulations. Always consult the Safety Data Sheet (SDS) for specific handling and disposal instructions to ensure safety.
