3-Hydroxydiphenylamine Chemical Properties, Uses, Production
Chemical Properties
Red brown soli
Uses
3-Hydroxydiphenylamine is used as an intermediate in dyes, pharmaceuticals, and rubber additives.
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.
