1,2,3,4-Tetrachloro-5,6-Dimethylbenzylene Chemical Properties,Usage,Production

General Description

A powdered or flaked solid. Insoluble in water. Very strongly irritates skin, eyes or mucous membranes. May be toxic by ingestion.

Air & Water Reactions

Insoluble in water.

Reactivity Profile

Simple aromatic halogenated organic compounds, such as TETRACHLORO-O-XYLENE, are very unreactive. Reactivity generally decreases with increased degree of substitution of halogen for hydrogen atoms. Materials in this group may be incompatible with strong oxidizing and reducing agents. Also, they may be incompatible with many amines, nitrides, azo/diazo compounds, alkali metals, and epoxides.

Health Hazard

TOXIC; inhalation, ingestion or skin contact with material may cause severe injury or death. Contact with molten substance may cause severe burns to skin and eyes. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.

Fire Hazard

Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Some are oxidizers and may ignite combustibles (wood, paper, oil, clothing, etc.). Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated.
