What is Disperse Blue 27 ?
Preparation
2-(4-Aminophenyl)ethanol and 4-(4-Hydroxyethylanilino)-5-nitro-1,8-dihydroxyanthraquinone?condensation.
General Description
Dark blue to black powder.
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.
