2-Hydroxyethyl methacrylate Usage And Synthesis

Chemical Propertiescolourless liquid
Uses2-Hydroxyethyl methacrylate is used for preparation of hydrophilic polymers for biomedical devices.
Uses2-Hydroxyethyl methacrylate is the methacrylic monomer for use in UV inks, adhesives, lacquers, dental materials, artificial nails, etc.
Definition2-Hydroxyethyl methacrylate is an enoate ester that is the monomethacryloyl derivative of ethylene glycol.
Hazard30% grade (with xylene): Flammable, moderate fire risk.
Purification MethodsDissolve the ester in water and extract with n-heptane to remove ethylene glycol dimethacrylate (checked by gas-liquid chromatography and by NMR) and distil it twice under reduced pressure [Strop et al. J Phys Chem 80 694 1976]. [Beilstein 2 IV 1530.]
