3-Hydroxydiphenylamine Usage And Synthesis

Chemical Properties

Red brown soli

Definition

ChEBI: 3-hydroxydiphenylamine is a substituted aniline.

General Description

Beige powder.

Air & Water Reactions

Insoluble in water.

Reactivity Profile

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

The flash point of 3-Hydroxydiphenylamine has not been determined, but 3-Hydroxydiphenylamine is probably combustible.
