4-Hydroxydiphenylamine isopropyl ether

dark grey solid

Rubber antioxidant.

Dark gray flakes or flaky black solid.

Insoluble in water.

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.

ACUTE/CHRONIC HAZARDS: When heated to decomposition 4-HYDROXYDIPHENYLAMINE ISOPROPYL ETHER emits toxic fumes of nitrogen oxides.

Flash point data for 4-HYDROXYDIPHENYLAMINE ISOPROPYL ETHER are not available; however, 4-HYDROXYDIPHENYLAMINE ISOPROPYL ETHER is probably combustible.
