Allyl chloride (3-chloropropene) 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 especially dangerous for fish and has the formula CH 2 = CH – CH 2 Cl.

Extraction and presentation

Allyl chloride is made by reacting propene with chlorine . Since the addition of chlorine to the double bond to form 1,2-dichloropropane is preferred at low temperatures, the process is carried out industrially at high temperatures (~ 500 ° C) in order to exchange one of the hydrogen atoms in the allyl position for chlorine via a radical reaction.

properties

Allyl chloride melts at −136 ° C and boils at 45 ° C. The auto-ignition temperature is 390 ° C. The density is slightly smaller than that of water and is 0.94 g · cm −3 . With Lewis acids , and base metals such as aluminum or magnesium allyl chloride is violent reactions a.

use

Allyl chloride is the raw material for paint and polymer additives, silicones , water treatment products and pharmaceuticals. More than 90% of the allyl chloride produced worldwide is converted into epichlorohydrin .

safety instructions

Allyl chloride is a contact poison and can also be absorbed through the skin . In the eyes it causes swelling, redness and a blurred vision and can lead to complete blindness . In addition, skin reddening, body aches, vomiting , coughing , sore throat and headache , dizziness can occur. Long-term contact with allyl chloride can cause death .
