For product formulators, understanding the chemical nuances of raw materials is key to innovation and success. Aniline Black, identified by CAS number 13007-86-8, is a complex organic pigment that offers unique advantages for those seeking superior black coloration. As a leading manufacturer and supplier, we provide detailed insights into this pigment's properties and applications, helping you make informed purchasing decisions.

Chemical Composition and Structure
Aniline Black (CAS 13007-86-8) is an azine derivative with the molecular formula C66H51Cr3N11O12 and a molecular weight of 1346.17. Its intricate structure contributes to its distinctive color properties and performance characteristics. While the exact synthesis involves the oxidation of aniline derivatives, its complex nature results in a pigment that offers a deep, neutral black with a subtle blue undertone, distinguishing it from simpler black colorants.

Key Technical Properties for Formulators
Formulators will find the following properties particularly beneficial when working with Aniline Black:

  • Appearance: A fine black powder, indicating ease of dispersion.
  • pH: Typically between 4.5-6.0, which is generally compatible with many formulation systems.
  • Water Content: Low water content (≤6.0%) ensures good stability and prevents issues in moisture-sensitive applications.
  • Oil Absorption: Around 35 g/100g, this parameter is important for understanding the pigment's interaction with binders and solvents in paints and inks.
  • Particle Size: Ranging from 0.03-1.8 μm, these fine particles contribute to its excellent hiding power and color strength.
These specifications highlight why Aniline Black is a preferred choice for many industrial applications. When you buy this pigment from a trusted China supplier, you can expect consistency in these critical parameters.

Optimizing Use in Formulations
To achieve the best results, Aniline Black should be properly dispersed within the medium. Its insolubility in water but solubility in certain organic solvents (like xylene, methanol, ethyl acetate, and acetone) dictates its suitability for solvent-based systems. For formulators looking to buy Aniline Black for inks or coatings, understanding its dispersibility in specific solvent systems is key to achieving optimal color development and stability. We provide technical guidance to help you integrate this pigment effectively into your product development.
