• 説明

  Ethyl Methacrylate is the ester of ethyl alcohol and methacrylic acid. Other chemical names for this compound are Ethyl 2- Methyl-2-Propenoate; 2-Methyl-2-Propenoic Acid, Ethyl Ester; 2-Propenoic Acid, 2-Methyl-, Ethyl Ester; and Methyacrylic Acid, Ethyl Ester. It is a colorless liquid with a melting point below -75℃, a boiling point of 119℃, and a specific gravity of 0.911. It has a molecular weight of 114.14 Da, a refractive index (n, 25/D) of 1.4116, and a flash point (OC) of 70℃. Ethyl Methacrylate has an acrid acrylate odor and is soluble in alcohol and ether. It is readily polymerized and is chemically reactive. Ethyl Methacrylate monomer is very hydrophobic and poorly “wets” the hydrophilic keratin surface of the nail plate, requiring hydrophilic nail primers and additives to obtain sufficient adhesion[1].

• 化学的特性

  Ethyl methacrylate is a clear, colorless, and highly flammable liquid that polymerizes but at a slower rate than that of the parent acrylate.

• 使用

  Ethyl methacrylate can be manufactured via a reaction of methacrylic acid or methyl acrylate with ethanol. It is used primarily for manufacturing polymers and as a component of acrylic polymers for surface coatings and as a structural monomer for some artificial fingernail formulations.

• 調製方法

  Ethyl methacrylate can be manufactured via a reaction of methacrylic acid or methyl acrylate with ethanol.

• 一般的な説明

  A colorless moderately toxic liquid with an acrid odor. Flash point of 70°F. Boiling point 278°F. Vapors irritate the eyes and respiratory system. Less dense than water. Not soluble in water. Used to make polymers and other chemicals.

• 空気と水の反応

  Highly flammable. A very dangerous fire and explosion hazard. Not soluble in water.

• 反応プロフィール

  May polymerize if heated for prolonged periods or accidentally contaminated. If polymerization takes place inside a container, the container may violently rupture. Can react with oxidizing materials. When heated to decomposition Ethyl methacrylate emits irritating fumes and acrid smoke [Sax, 9th ed., 1996, p. 1576].

• 危険性

  Flammable, dangerous fire and explosion hazard. An irritant.

• 健康ハザード

  Inhalation may cause irritation of the mucous membrane. Ingestion causes irritation of mouth and stomach. Contact with liquid irritates eyes and skin.

• 火災危険

  Behavior in Fire: Sealed containers may rupture explosively if hot. Heat can cause a violent polymerization reaction with rapid release of energy. Vapors are heavier than air and can travel to a source of ignition and flash back.

• 化学反応性

  Reactivity with Water No reaction; Reactivity with Common Materials: No reaction; Stability During Transport: Stable; Neutralizing Agents for Acids and Caustics: Not pertinent; Polymerization: If proper concentration of inhibitor is not present or when material is hot, a violent polymerization reaction may occur; Inhibitor of Polymerization: Oxygen in the air inhibits polymerization.

• 安全性プロファイル

  Moderately toxic by ingestion and intraperitoneal routes. Mildly toxic by inhalation. Experimental teratogenic and reproductive effects. A skin irritant. A very dangerous fire and explosion hazard when exposed to heat, sparks, or flame; can react with oxidzing materials. To fight fire, use CO2, dry chemical. When heated to decomposition it emits acrid smoke and irritating fumes.

• 発がん性

  Not listed by ACGIH, California Proposition 65, IARC, NTP, or OSHA.

• 純化方法

  Wash the ester successively with 5% aqueous NaNO2, 5% NaHSO3, 5% NaOH, then water. Dry it over MgSO4, add 0.2% (w/w) of phenyl-.-naphthylamine, and distil it through a short Vigreux column (p 11) [Schultz J Am Chem Soc 80 1854 1958]. [Beilstein 2 IV 1523.]
