For those involved in chemical formulation and material science, a thorough understanding of pigment specifications is paramount. Pigment Yellow 14 (PY14), with CAS number 5468-75-7, presents a compelling profile of chemical and physical properties that dictate its suitability for various applications. Its chemical formula, C34H30Cl2N6O4, reveals a complex organic structure that contributes to its color and performance characteristics.

Key technical specifications for Pigment Yellow 14 include:

Chemical Identity: Chemical Name: 2,2′-[(3,3′-Dichlorobiphenyl-4,4′-diyl)bis(azo)]bis[N-(2-methylphenyl)-3-oxobutanamide]. The CAS Number is 5468-75-7, and its EC Number is 226-789-3. This classification helps in identifying and referencing the substance accurately within the industry.


Physical Properties: PY14 typically appears as a yellow powder. Its density generally falls within the range of 1.4 to 1.6 g/cm³, and it has a melting point around 336°C, although some sources cite a decomposition range around 180-200°C for processing stability. The specific surface area can vary, influencing its dispersibility.


Fastness Properties: A significant advantage of Pigment Yellow 14 is its resistance to various agents. It exhibits good resistance to solvents (like xylene, ethanol, ethyl acetate), acids (e.g., 5% HCl), alkalis (e.g., 5% NaOH), and water. Its lightfastness is rated as moderate, typically 3-4 on a scale where 8 is excellent. This makes it suitable for applications where prolonged UV exposure is not a primary concern.


Thermal Stability: Pigment Yellow 14 can generally withstand processing temperatures up to 180°C, making it compatible with many common manufacturing processes in plastics and inks. Exceeding these temperatures can lead to thermal decomposition.


Solubility: It is insoluble in water but slightly soluble in some organic solvents like toluene. This insolubility is crucial for its pigmentary function, preventing it from dissolving into the medium it colors.
