The Uses of o-Phenetidine

manufacture of dyes.

Definition

ChEBI: o-Phenetidine is a substituted aniline and an aromatic ether. It is used in the manufacture of acetophenetidin.

Preparation

o-Phenetidine is produced from 2- ethoxynitrobenzene by reduction with iron or by catalytic hydrogenation in the presence of precious-metal catalysts or Raney nickel.

General Description

Reddish brown oily liquid.

Air & Water Reactions

o-Phenetidine is very sensitive to exposure to light and air. . Slightly soluble in water.

Reactivity Profile

o-Phenetidine neutralizes acids in exothermic reactions to form salts plus water. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen may be generated in combination with strong reducing agents, such as hydrides.

Fire Hazard

o-Phenetidine is probably combustible.

Safety Profile

Moderately toxic by ingestion. When heated to decomposition it emits toxic vapors of NOx.
