Chloroethane is a chemical compound that can be used as synthetic Ethylierungsreagenz. Other names are ethyl chloride, ethyl chloride, Monochloräthan, hydrochloric ether, light ether salt, Kelen and Chelen.

Production and representation

Chloroethane may be prepared by addition of hydrogen chloride to ethylene at elevated temperatures with aluminum chloride catalysts. The process is exothermic.

Properties

Physical Properties

Chloroethane vapors are heavier than air and will accumulate at the bottom of ( " heavy gas "). It has a critical temperature of 187.2 ° C, a critical pressure of 52.7 bar, a critical density of 0.331 kg / l and a triple point temperature of -138.3 ° C (melting temperature).

Chemical Properties

Chloroethane is gaseous under normal conditions, very responsive and sensitive to light. In the thermal decomposition without oxygen, hydrogen chloride and ethylene. In air and exposed to light, it slowly decomposes to form hydrogen chloride and phosgene.

Use

Chloroethane is practically only used industrially because of the difficulty of handling such as Ethylierungs, solvent and extractant. In medicine it is used for local anesthesia (freezing ). Industrial chloroethane was an important starting material for the production of the anti-knock additive tetraethyl lead for fuels.

Safety

Chloroethane is highly flammable and harmful, possibly even carcinogenic.
