2,6-DICHLORO-1,4-PHENYLENEDIAMINE Usage And Synthesis

Chemical Properties

grey powder

Uses

The compound has been used as an intermediate for dyes, to some extent in preparing certain polyamide fibers, and as a curing agent for polyurethane.

Uses

2,6-Dichloro-1,4-phenylenediamine is an aromatic amine that can be found in azo dyes. It was studied for potential mutagenic and toxic properties.

Definition

ChEBI: 2,6-Dichloro-para-phenylenediamine is a dichlorobenzene.

Preparation

The chromophore Preparation: Will 2,6-Dichioro-4-nitroaniline reduction.

Production Methods

2,6-Dichloro-p-PDA is not currently produced in the United States; the sole manufacturer ceased production in 1978. It is a chemical intermediate used as a polyurethane curative, and as a monomer in the manufacture of polyamide fiber.

General Description

Gray, microcrystalline powder or solid.

Air & Water Reactions

2,6-DICHLORO-1,4-PHENYLENEDIAMINE may be unstable to prolonged exposure to air and light. . Insoluble in water.

Reactivity Profile

2,6-DICHLORO-1,4-PHENYLENEDIAMINE neutralizes acids in exothermic reactions. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. May generate flammable gaseous hydrogen in combination with strong reducing agents, such as hydrides.

Health Hazard

ACUTE/CHRONIC HAZARDS: When 2,6-DICHLORO-1,4-PHENYLENEDIAMINE is heated to decomposition it emits very toxic fumes of chlorine and nitrogen oxides.

Fire Hazard

Flash point data for 2,6-DICHLORO-1,4-PHENYLENEDIAMINE are not available; however, 2,6-DICHLORO-1,4-PHENYLENEDIAMINE is probably combustible.
