Uses and applications

What the substance is used for, by industry and function

Reagent and chemical intermediate. Solvent for paint, varnishes, degreaser.

1,1-Dichlorethane is used as a chemical intermediate and grain fumigant and has limited use as a solvent for plastics, oils, and fats. It was formerly used as an anesthetic but it is of no importance in this field today.

Used in the manufacture of high vacuum rubber and silicone grease.

Primarily used as a feedstock for the production of 1,1,1-trichloroethane.

Most commonly used in the production of vinyl chloride monomer (1,2-dichloroethane).

Industrial uses: Intermediate.

Use classes: Volatile organic compounds.

Functional uses

  • Solvent

How it is made

Prepared by the action of PCl5 (phosphorus pentachloride) on acetaldehyde.

1,1-Dichloroethane may ... be obtained by ethane or chloroethane chlorination. This chlorination can be carried out as thermal chlorination, photochlorination, or oxychlorination. These processes, however, are impaired by a lack of selectivity.

1,1-Dichloroethane can be produced from acetylene by adding 2 mol of hydrogen chloride. For the first reaction sequence, i.e., the formation of vinyl chloride, mercury catalyst is typically used, although other nonmercuric catalysts are claimed in the literature.
