The IUPAC name of Ethyl methacrylate is ethyl 2-methylprop-2-enoate. With the CAS registry number 97-63-2, it is also named as Methacrylic acid, ethyl ester. The product's categories are EQ - EZ; EQ - EZ Analytical Standards; Esters Gasoline, Diesel & Petroleum; Alpha Sort; Chemical Class; E-LAlphabetic; Olefins; Substance Classes; Volatiles / Semivolatiles; Acrylic Monomers; C6 to C7 Monomers; Carbonyl Compounds; Esters; Methacrylate. It is colourless liquid with an unpleasant odour which is incompatible with peroxides, oxidizing agents, bases, acids, reducing agents, halogens and amines. It can polymerize in the presence of light or heat. If polymerization takes place inside a container, the container may violently rupture. When heated to decomposition Ethyl methacrylate emits acrid smoke and irritating fumes. Additioanlly, this chemical should be sealed in the container and stored in the cool and dry place.

Preparation of Ethyl methacrylate: It can be obtained by esterification of methacrylic acid and ethanol. Putting methacrylic acid and ethanol to reactor and adding a small amount of concentrated sulfuric acid. Heating and refluxing to occur ester layer. Cooling and separating the ester layer. After caustic washing, water washing, drying and vacuum fractionation, we can get the product.

Uses of Ethyl methacrylate: It is used in the manufacture of acrylates copolymers, adhesives and coatings. It is also used in organic synthesis, in the preparation of plexiglass and as a solvent. In addition, it can react with piperidine to get b-piperidino-isobutyric acid ethyl ester. This reaction needs reagent acetic acid at temperature of 70 °C. The reaction time is 17 hours. The yield is 82%.

When you are using this chemical, please be cautious about it as the following:
It is highly flammable, so people should keep it away from sources of ignition and keep container in a well-ventilated place. It is also irritating to eyes, respiratory system and skin, so people should not empty into drains and must take precautionary measures against static discharges.
