Allyl chloride supplier Distributor Manufacturer in chennai Taminadu india

Allyl chloride is the organic compound with the formula CH2=CHCH2Cl. This colorless liquid is insoluble in water but soluble in common organic solvents. It is mainly converted to epichlorohydrin, used in the production of plastics. It is a chlorinated derivative of propylene. It is an alkylating agent, which makes it both useful and hazardous to handle.

Production

Laboratory scale

Allyl chloride was first produced in 1857 by Auguste Cahours and August Hofmann by reacting allyl alcohol with phosphorus trichloride. Modern preparation protocols economize this approach, replacing relatively expensive phosphorus trichloride with hydrochloric acid and a catalyst such as copper(I) chloride.

Industrial scale

Allyl chloride is produced by the chlorination of propylene. At lower temperatures, the main product is 1,2-dichloropropane, but at 500 °C, allyl chloride predominates, being formed via a free radical reaction:

CH3CH=CH2 + Cl2 → ClCH2CH=CH2 + HCl
An estimated 800,000 metric tons were produced this way in 1997.

Reactions and uses

The great majority of allyl chloride is converted to epichlorohydrin.Other commercially significant derivatives include allyl alcohol, allylamine, allyl isothiocyanate (synthetic mustard oil) and allylsilane.

As an alkylating agent, it is useful in the manufacture of pharmaceuticals and pesticides, such as mustard oil.
