  • Beschreibung Methyl acrylate is an organic compound with the formula CH2CHCO2CH3. It is the methyl ester of acrylic acid. It is a colourless liquid with a characteristic acrid odor. It is mainly produced to make acrylate fiber, which is used to weave synthetic carpets. It is also a reagent in the synthesis of various pharmaceutical intermediates.
  • Chemische Eigenschaften Methyl acrylate is a clear, colorless liquid with a sharp, fruity odor.
  • Chemische Eigenschaften colourless liquid
  • Verwenden Acrylic polymers, amphoteric surfactants, vitamin B 1, chemical intermediate.
  • Verwenden Methyl acrylate is a monomer used in themanufacture of plastic films, textiles, papercoatings, and other acrylate ester resins. It isalso used in amphoteric surfactants.
  • Definition methacrylate: A salt or ester ofmethacrylic acid (2-methylpropenoicacid).
  • Allgemeine Beschreibung Colorless volatile liquid with an acrid odor. Flash point 27°F. Vapors may irritate the eyes and respiratory system. Highly toxic by inhalation, ingestion and skin absorption. Less dense than water (0.957 gm / cm3) and slightly soluble in water, hence floats on water. Vapors heavier than air.
  • Air & Water Reaktionen Highly flammable. Forms peroxides when exposed to air that may initiate spontaneous, exothermic polymerization. Peroxide formation usually proceeds slowly. Slightly soluble in water.
  • Reaktivität anzeigen METHYL ACRYLATE ignites readily when exposed to heat, flame or sparks. Offers a dangerous fire and explosion hazard. Reacts vigorously with strong oxidizing materials. Forms peroxides when exposed to air that may initiate spontaneous exothermic polymerization. Peroxide formation usually proceeds slowly. Added inhibitor retards polymerization. If the inhibitor is consumed during long storage, explosive polymerization may occur [MCA Case History No. 2033]. Also subject to strongly exothermic polymerization if heated for prolonged periods or contaminated.
  • Hazard Flammable, dangerous fire and explosion risk. Toxic by inhalation, ingestion, and skin absorption; irritant to skin, eyes and upper respiratory tract irritant; eye damage. Questionable carcinogen.
  • Health Hazard The liquid is a strong irritant, and prolongedcontact with the eyes or skin may causesevere damage. Inhalation of its vapors cancause lacrimation, irritation of respiratorytract, lethargy, and at high concentrations,convulsions. One-hour exposure to a concen tration of 700–750 ppm in air caused deathto rabbits. The oral toxicity of methyl acry late in animals varied from low to moderate,depending on species, the LD50 values ranging between 250 and 850 mg/kg. The liquidmay be absorbed through the skin, producingmild toxic effects.
  • Health Hazard May irritate skin, eyes, respiratory system, and gastro- intestinal tract. Fumes cause tears.
  • Brandgefahr Flammable liquid; flash point (closed cup) -4°C (25°F), (open cup) -3°C (27°F); vapor pressure 68 torr at 20°C (68°F); vapor density 3.0 (air = 1); the vapor is heavier than air and can travel a considerable distance to a source of ignition and flashback; autoignition tem perature not established; fire-extinguishing agent: dry chemical, CO2, or “alcohol” foam; use water to keep the fire-exposed containers cool and to flush or dilute any spill; the vapors may polymerize and block the vents.
    The vapors of methyl acrylate form explo sive mixtures with air, over a relatively wide range; the LEL and UEL values are 2.8 and 25.0% by volume in air, respectively. Methyl acrylate undergoes self-polymerization at 25°C (77°F). The polymerization reaction proceeds with evolution of heat and the increased pressure can cause rupture of closed containers. The reaction rate is accelerated by heat, light, or peroxides. Vigorous to violent reaction may occur when mixed with strong oxidizers (especially nitrates and peroxides) and strong alkalie.
  • Sicherheitsprofil Poison by ingestion and intraperitoneal routes. Moderately toxic by skin contact. Mddly toxic by inhalation. Human systemic effects by inhalation: olfaction effects, eye effects, and respiratory effects. A skin and eye irritant. Mutation data reported. Chronic exposure has produced injury to lungs, liver, and kidneys in experimental animals. Questionable carcinogen. Dangerously flammable when exposed to heat, flame, or oxidzers. Dangerous explosion hazard in the form of vapor when exposed to heat, sparks, or flame. Can react vigorously with oxidzing materials. A storage hazard; it forms peroxides, which may initiate exothermic polymerization. To fight fire, use foam, COa, dry chemical. When heated to decomposition it emits acrid smoke and irritating fumes. See also ESTERS.
  • Sicherheit(Safety) It is an acute toxin with an LD50 (rats, oral) of 300 mg/kg and a TLV of 10 ppm.
  • mögliche Exposition Methyl acrylate is used in production of acrylates, copolymers, barrier resins; and surfactants for shampoos; as a monomer in the manufacture of polymers for plastic films, textiles, paper, and leather coating resins. It is also used as a pesticide intermediate and in pharmaceutical manufacture.
  • Erste Hilfe If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medical attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit. Medical observation is recommended for 24 to 48 hours after breathing overexposure, as pulmonary edema may be delayed. As first aid for pulmonary edema, a doctor or authorized paramedic may consider administering a drug or other inhalation therapy.
  • Lager Methyl acrylate is stored in a flammablematerials storage room or cabinet below20°C (68°F), separated from oxidizing substances. It is inhibited with 200 ppm ofhydroquinone monomethyl ether to preventself-polymerization. It is shipped in bottles,cans, drums, or tank cars.
  • Versand/Shipping UN1919 Methyl acrylate, stabilized, Hazard Class: 3; Labels: 3-Flammable liquid.
  • läuterung methode Wash the ester repeatedly with aqueous NaOH until free from inhibitors (such as hydroquinone), then wash it with distilled water, dry (CaCl2) and fractionally distil it under reduced pressure in an all-glass apparatus. Seal it under nitrogen and store it at 0o in the dark. [Bamford & Han J Chem Soc, Faraday Trans 1 78 855 1982, Beilstein 2 IV 1457.]
  • Inkompatibilitäten Forms explosive mixture in air. Incompatible with nitrates, oxidizers, such as peroxides, strong alkalis. Polymerizes easily from heat, light, peroxides; usually contains an inhibitor, such as hydroquinone.
  • Waste disposal Dissolve or mix the material with a combustible solvent and burn in a chemical incinerator equipped with an afterburner and scrubber. All federal, state, and local environmental regulations must be observed. Consult with environmental regulatory agencies for guidance on acceptable disposal practices. Generators of waste containing this contaminant (≥100 kg/mo) must conform to EPA regulations governing storage, transportation, treatment, and waste disposal
