Products Description of Trans-1,2-Dichloroethylene CAS#156-60-5
Trans-1,2-dichloroethylene is a colorless, volatile liquid with a slightly pungent odor. It is flammable, and its vapor can form explosive mixtures with air. Exposure to open flames or high temperatures may result in fire or explosion. When heated in air, the compound can decompose to produce highly toxic phosgene and hydrogen chloride gas. It also reacts vigorously with oxidizing agents and can form explosive chloroacetylene upon contact with copper or its alloys.

Product Application of Trans-1,2-Dichloroethylene CAS#156-60-5
Compared with cis-1,2-dichloroethylene, trans-1,2-dichloroethylene is less toxic and exhibits greater chemical reactivity. It is primarily used in industry as an extractant for heat-sensitive substances, a solvent for certain polymer materials, and a raw material for organic synthesis. It also serves as a solvent for fats, phenols, camphor, and other substances, with applications in dyes, fragrances, paints, thermoplastics, and degreasing agents.
