Usage

Description

Dichloroethane is a colorless and transparent oily liquid with a chloroform-like odor and a sweet taste. It is very soluble in water, miscible with ethanol, chloroform, and ether, and can dissolve oil, grease, and paraffin. It is mainly used as a solvent.

Uses

Used in Chromatography:
Dichloroethane is used as a standard reagent for chromatography, providing a reliable and consistent reference for analyzing and separating compounds.
Used in Chemical Synthesis:
Dichloroethane is used as a raw material for organic synthesis, contributing to the production of various chemical compounds and products.
Used in Resin and Rubber Industries:
Dichloroethane is used as a solvent for resins and rubber, aiding in the manufacturing process and improving the properties of the final products.
Used in Cellulose Processing:
Dichloroethane is used as a solvent for cellulose acetate and cellulose esters, facilitating the processing and production of cellulose-based materials.
Used in Paints and Polymers:
Dichloroethane is used as a solvent for paints and polymers such as polystyrene, enhancing their properties and aiding in their application.
Used in Photography and Xerographic Printing:
Dichloroethane is used in photography and xerographic printing, playing a crucial role in the development and reproduction of images.
Used in Water Softening:
Dichloroethane is used in water softening processes, helping to remove minerals and improve water quality.

Incompatibility

Dichloroethane is incompatible with strong oxidizing agents, strong bases, chemically active metals (such as aluminum or magnesium powder, sodium, potassium).

Storage

Dichloroethane can be contained in metal cylinders to prevent mechanical damage. It should be stored in a cool and ventilated place, preferably in the open air or in an attached warehouse; indoors should be placed in a standard flammable liquid warehouse, away from fire sources. Separated from oxidants.

Toxicity

Acute oral LD50: 670-890 mg/kg for rats, 870-950 mg/kg for mice, and 860-970 mg/kg for rabbits. A single overdose or repeated exposure to dichloroethane can damage the liver and kidneys. From the perspective of chronic toxicity, it is safer than carbon tetrachloride. In practice, most people cannot tolerate or vomit at sublethal concentrations of dichloroethane.
