Specification

The IUPAC name of Methyl methacrylate is methyl 2-methylprop-2-enoate. With the CAS registry number 80-62-6, it is also named as 2-Methyl-2-propenoic acid methyl ester. The product's categories are Low Refractive Index Monomers; Acrylic Monomers; Carbonyl Compounds; Esters; Methacrylate; Waveguide Materials; META - METH Cosmetics; Allergens; Alpha Sort; MAlphabetic; Other Additives; Volatiles/ Semivolatiles. It is clear colorless liquid which is slightly soluble in water, soluble in alcohol, ether, acetone and other organic solvents. In addition, this chenical is flammable by fire, heat and oxidants. Besides, it should be sealed in the container and stored in the cool and dry place.

The other characteristics of Methyl methacrylate can be summarized as:
(1)ACD/LogP: 1.35; (2)# of Rule of 5 Violations: 0; (3)ACD/LogD (pH 5.5): 1.35; (4)ACD/LogD (pH 7.4): 1.35; (5)ACD/BCF (pH 5.5): 6.2; (6)ACD/BCF (pH 7.4): 6.2; (7)ACD/KOC (pH 5.5): 128.53; (8)ACD/KOC (pH 7.4): 128.53; (9)#H bond acceptors: 2; (10)#H bond donors: 0; (11)#Freely Rotating Bonds: 2; (12)Index of Refraction: 1.4; (13)Molar Refractivity: 26.55 cm³; (14)Molar Volume: 109.4 cm³; (15)Polarizability: 10.52×10^-24 cm³; (16)Surface Tension: 23.5 dyne/cm; (17)Enthalpy of Vaporization: 33.96 kJ/mol; (18)Vapour Pressure: 36.9 mmHg at 25°C; (19)Rotatable Bond Count: 2; (20)Exact Mass: 100.05243; (21)MonoIsotopic Mass: 100.05243; (22)Topological Polar Surface Area: 26.3; (23)Heavy Atom Count: 7; (24)Complexity: 94.3.

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 Methyl methacrylate, 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.
