Methacryloyl chloride Chemical Properties,Uses,Production
Chemical Properties
clear slightly colored liquid
Uses
Methacryloyl chloride is used in the preparation of polymeric materials. It reacts with L-histidine and forms functional monomer. It is also used to prepare monomer 2-methacrylamido-caprolactam, amide monomers by amidation.
Application
Methacryloyl chloride is used in the manufacture of polymers:
Monomer 2-methacrylamido-caprolactam was prepared by reacting methacryloyl chloride with racemic a-amino-e-caprolactam.
Functional monomer was prepared by reacting methacryloyl chloride and L-histidine.
A series of amide monomers were synthesized by amidation of methacryloyl chloride with amines and grafted onto commercial poly(ether sulfone) (PES) membranes using irradiation from atmospheric pressure plasma (APP).
Reaction of methacryloyl chloride with the hydroxyl groups on the surfaces of HEMA/NVP microspheres was performed, leading to the introduction of polymerisable double bonds onto the surfaces of microspheres.
Star-shaped poly(d,l-lactide) oligomers with 2, 3 and 6 arms were synthesised, end-functionalised with methacryloyl chloride and photo-crosslinked in the presence of ethyl lactate as a non-reactive diluent.
General Description
Methacryloyl chloride is the clear to slightly colored acid chloride of methacrylic acid. It appears as a liquid of density 1.07g/cm3, boiling point 95-96°C, and flash point 55°F. Highly toxic. Supplied in technical grades of varying purity. Monomethyl ether hydroquinone is added as a stabilizer to prevent auto polymerization. Reaction with diisopropyl ether in presence of metal salts is rigorous.
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.]
