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 used in UV-curable inks and coatings. It is also used in adhesives, artificial nails, dental materials and lacquers. In dentistry, it is one of the main volatile acrylates along with methyl methacrylate. Further, it is used as a monomer in the synthesis of polymers for dental prosthetics and for geotechnical grouting in construction work.
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.
General Description2-Hydroxyethyl methacrylate (HEMA) is biocompatible in nature. Polymeric hydrogel scaffold can be produced by polymerizing HEMA in water.
Hazard30% grade (with xylene): Flammable, moderate fire risk.
Environmental Fate 2-Hydroxyethyl methacrylate's production and use in acrylic resins, enamels, and as a binder for non-woven fabrics may result in its release to the environment through various waste streams. If released into the air, a vapor pressure of 0.126 mm Hg at 25 °C indicates that 2-hydroxyethyl methacrylate will exist solely as a vapor in the ambient atmosphere. Vapor-phase 2-hydroxyethyl methacrylate will be degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals; the half-life for this reaction in air is estimated to be 16 hours. If released to soil, 2-hydroxyethyl methacrylate is expected to have very high mobility based upon an estimated Koc of 43. Volatilization from moist soil surfaces is not expected to be an important fate process based upon an estimated Henry's Law constant of 4.6X10-9 atm-cu m/mole. 2-Hydroxyethyl methacrylate is not expected to volatilize from dry soil surfaces based on its vapor pressure. If released into water, 2-hydroxyethyl methacrylate is not expected to adsorb to suspended solids and sediment in the water column based on the estimated Koc. 2-Hydroxyethyl methacrylate reached 92-100% of its theoretical BOD in 2 weeks using an activated sludge inoculum. Volatilization from water surfaces is not expected to be a necessary fate process based on this compound's estimated Henry's Law constant. An estimated BCF of 1.3 suggests the potential for bioconcentration in aquatic organisms is low. Hydrolysis of 2-hydroxyethyl methacrylate may be a significant process under basic conditions based upon a hydrolytic half-life of 4 hours at pH 11 for the structurally similar butyl acrylate; half-lives for butyl acrylate at pH 7, 8, and 9 were 4 years, 150 days, and 15 days, respectively. Occupational exposure to 2-hydroxyethyl methacrylate may occur through inhalation and dermal contact with this compound at workplaces where 2-hydroxyethyl methacrylate is produced or used. The general population may be exposed to 2-hydroxyethyl methacrylate via inhalation or dermal contact with acrylic resins or enamels containing this compound.
Metabolism2-hydroxyethyl methacrylate (HEMA) is a monomer based on methacrylic acid (MAA) used to produce biomaterials such as dental adhesive and composite resins. The process of polymerization, which is run in situ, is always incomplete, resulting in the presence of free monomers in the oral cavity. Moreover, monomers can be released from polymer-based tooth restorations through mechanical shearing and enzymatic degradation of polymers. They may penetrate the pulp through microchannels in the dentin structure. HEMA, like many of MAA-based monomers, is an ester, so it can be targeted by esterases when in organism and can undergo degradation. The main product of HEMA hydrolysis is MAA, which may undergo further degradation producing several intermediates of potential biological activity[1].
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.]
