Preparation of Methyl methacrylate: It is produced by the acetone cyanohydrin process in which the acetone cyanohydrin (from the reaction of acetone with hydrogen cyanide, q.v.) is reacted with sulfuric acid to yield methacrylamide sulfate, which is further hydrolyzed and esterified. The process is continuous.
CH₃C(OH·CN)CH₃ + H⁺ → CH₂=C(CH₃)C(=O)NH₃⁺
CH₂=C(CH₃)C(=O)NH₃⁺ + CH₃OH + HSO₄^- → CH₂=C(CH₃)C(=O)OCH₃ + NH₄SO₄

Uses of Methyl methacrylate: It is used for the production of the co-polymer methyl methacrylate-butadiene-styrene (MBS), used as a modifier for PVC. The principal application of this chemical is the manufacture of polymethyl methacrylate acrylic plastics (PMMA). Methyl methacrylate is polymerized to poly(methyl methacrylate), which is used in cast and extruded sheet, molding powder and resins, surface coatings, impact modifiers, and emulsion polymers. In addition, it reacts with acetoacetic acid ethyl ester to get 2-acetyl-4-methyl-glutaric acid-1-ethyl ester-5-methyl ester. This reaction needs reagent sodium ethylate and ethanol.

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. It is not only toxic by inhalation, in contact with skin and if swallowed, but also irritating to eyes, respiratory system and skin. So people should avoid contact with skin. If you want to contact this product, you must wear suitable protective clothing and gloves. In case of accident or if you feel unwell, seek medical advice immediately (show the label whenever possible.) If swallowed, seek medical advice immediately and show this container or label.
