Description
Disperse Blue 27 is a synthetic azo dye characterized by its dark blue to black powder form. It is known for its excellent colorfastness properties, including resistance to ironing, light, perspiration, and washing, making it a popular choice for various applications in the textile and dyeing industries.
Uses
Used in Textile Industry:
Disperse Blue 27 is used as a colorant for dyeing synthetic fibers such as polyester, nylon, and acrylic. Its high colorfastness properties, including ironing fastness (ISO 5, AATCC 5), light fastness (ISO 4-5, AATCC 4-5), perspiration fastness (ISO 6-7, AATCC 6), and washing fastness (ISO 5, AATCC 5), make it an ideal choice for producing vibrant and long-lasting colors in textiles.
Used in Dyeing Industry:
Disperse Blue 27 is used as a dye for various applications in the dyeing industry, including the production of colored fabrics, garments, and other textile products. Its excellent colorfastness properties, such as resistance to fading (ISO 4, AATCC 5) and staining (ISO 4-5, AATCC 5), ensure that the colors remain vibrant and resistant to various environmental factors.
Preparation
2-(4-Aminophenyl)ethanol and 4-(4-Hydroxyethylanilino)-5-nitro-1,8-dihydroxyanthraquinone?condensation.
Air & Water Reactions
Soluble in water.
Reactivity Profile
An amine. Amines are chemical bases. They neutralize acids to form salts plus water. These acid-base reactions are exothermic. The amount of heat that is evolved per mole of amine in a neutralization is largely independent of the strength of the amine as a base. Amines may be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen is generated by amines in combination with strong reducing agents, such as hydrides.
Fire Hazard
Flash point data for Disperse Blue 27 are not available. Disperse Blue 27 is probably combustible.

Check Digit Verification of cas no
The CAS Registry Mumber 15791-78-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,7,9 and 1 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 15791-78:
(7*1)+(6*5)+(5*7)+(4*9)+(3*1)+(2*7)+(1*8)=133
133 % 10 = 3
So 15791-78-3 is a valid CAS Registry Number.

This invention pertains to certain novel colorant compounds containing one or more ethylenically-unsaturated, photopolymerizable radicals that may be copolymerized (or cured) with ethylenically-unsaturated monomers to produce colored compositions such as colored acrylic polymers. Suitable compositions having the present colorants copolymerized therein include, e.g., polymers produced from acrylate and methacrylate esters, colored polystyrenes, and similar colored polymeric materials derived from other ethylenically-unsaturated monomers. The present invention also pertains to processes for preparing the photopolymerizable colorant compounds. The ethylenically unsaturated colorant compounds may be suitable for use in coatings that are applied to wood, glass, metal, thermoplastics and the like.
