Methacryloyl chloride Usage And Synthesis

Chemical Properties

clear slightly colored liquid

Uses

Methacryloyl Chloride is widely used in the manufacture of polymers.

General Description

A liquid of density 1.07 g / cm3, boiling point 95-96°C, and flash point 55°F. Highly toxic. Supplied in technical grades of varying purity.

Air & Water Reactions

Highly flammable. Reacts with water to produce gaseous hydrogen chloride (corrosive and toxic).

Reactivity Profile

Methacryloyl chloride is incompatible with strong oxidizing agents, alcohols, bases (including amines). Can polymerize violently; but the polymerization reaction can be inhibited by the addition of phenolthiazine. May react vigorously or explosively if mixed with diisopropyl ether or other ethers in the presence of trace amounts of metal salts [J. Haz. Mat., 1981, 4, 291].

Hazard

Flammable and corrosive liquid.

Purification Methods

Purify the ester by fractional distillation. If it contains the acid (OH bands in the IR) then add redistilled SOCl2 (with cooling) and cuprous chloride (ca to 2%), reflux the mixture gently for 1hour and fractionate it through a 1metre column packed with glass helices. Redistillation then provides the acid chloride in high purity as a colourless liquid. It is necessary to keep the apparatus moisture free (use CaCl2 tubes), Stabilise it with 0.05% of 2,6-di-tert-butyl-4-methylphenol. [Lal & Green J Org Chem 20 1032 1955, Beilstein 2 IV 1537.]
