Properties and stability

Decomposes when heated or burned, producing toxic and corrosive fumes containing chlorine, hydrogen chloride and carbon monoxide. with�The oxidizing agent reacts.

Storage method

This product should be sealed and stored in a cool, dry place.

Synthesis method

1. The nontoxic body of 666 dried by pyrolysis method is heated in a pyrolysis kettle to obtain trichlorobenzene, and a large amount of hydrogen chloride is produced as a by-product. 2. Alkaline hydrolysis method: Trichlorobenzene is obtained by heating the nontoxic body of 666 with lime milk, and at the same time, a large amount of calcium chloride liquid is produced as a by-product. The trichlorobenzene obtained by the above two methods is a mixture of three isomers: 1,2,4-trichlorobenzene; 1,3,5-trichlorobenzene; 1,2,3-trichlorobenzene. , 4-trichlorobenzene is the main component. Among the trichlorobenzene produced by the lime milk method, the content of 1,2,4-trichlorobenzene is more than 75%, and 1,2,3-trichlorobenzene accounts for about 20%.

Purpose

Used as solvent and pharmaceutical intermediate. Used in the production of pesticides, dyes, transformer oil, electrolyte, lubricating oil and heat transfer media.
