DISPERSE BLUE 7 Usage And Synthesis
Uses
Disperse Blue 7 is a textile disperse dye. Dyes and metabolites, Environmental Testing.
Preparation
(a)1,4,5,8-Tetrahydroxyanthracene-9,10-dione in a small amount insurance powder with existing 2-Aminoethanol?condensation, Then the ammonia and boric acid or sodium hydroxide or oxidized in the presence piperidine;
General Description
Fine black powder.
Air & Water Reactions
Water soluble.
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
