Allyl chloride (3- chloroprene ) is a toxic, environmentally harmful and highly flammable liquid that evaporates at room temperature. The gaseous substance is heavier than air and has a pungent, mustard oil-like odor. Allyl chloride is particularly dangerous for fish and has the formula CH2 = CH- CH2Cl.

Production and representation

Allychlorid can be prepared by the reaction of propene with chlorine at elevated temperatures ( ~ 500 ° C).

Properties

Allyl chloride melts at -136 ° C and evaporated at 45 ° C. Self-ignition temperature is 390 ° C. The density is slightly less than that of water and of 0.94 g · cm -3. With base metals such as aluminum allyl chloride undergoes a violent reaction.

Use

Allyl chloride is the starting material for coatings and polymer additives, silicones, water treatment products and drugs. More than 90% of the allyl chloride produced worldwide are used for the production of epichlorohydrin.

Safety

Allyl chloride is a contact poison, and can be absorbed through the skin. On the eyes it causes swelling, redness and a blurred view and can lead to total blindness. In addition, skin redness, body aches, vomiting, cough, sore throat and headache, dizziness. Prolonged contact allyl chloride can lead to death.
