It is a flammable liquid with a characteristically pleasant smell. When released into the air, this material is expected to have a half-life of greater than 30 days. This material is not expected to significantly bioaccumulate. Local exhaust ventilation is generally preferred because it can control the emissions of the contaminant at its source, preventing dispersion of it into the general work area. Once the chemical process forms methyl acetate, it must be distilled for purity.
If a leak or spill has not ignited, use water spray to disperse the vapors, to protect personnel attempting to stop leak, and to flush spills away from exposures. Thirtieth Anniversary of the Retention Index According to Kovats in Gas-Liquid Chromatography, J. Sealed containers may rupture when heated. A full-face piece organic vapor respirator may be worn up to 50 times the exposure limit or the maximum use concentration specified by the appropriate regulatory agency or respirator supplier, whichever is lowest. The synthesis of methyl acetate is reversible, and due to the limitation of chemical equilibrium, the conversion yield is low. Volatile chemicals have a high risk of being aspirated into the victim's lungs during vomiting which increases the medical problems.
Dispose of container and unused contents in accordance with federal, state and local requirements. Information also provided for 3,600 nuclides and 4,400 nuclide decay modes. Affects the central nervous system. Skin Contact: Immediately flush skin with plenty of water for at least 15 minutes. Do not touch or walk through spilled material. If breathing is difficult, give oxygen.
Use non-sparking tools and equipment. No one should ever enter into a hazardous environment without proper training from qualified instructors. Contain and recover liquid when possible. The top supplying countries are China Mainland , India, and South Africa, which supply 94%, 2%, and 1% of methyl acetate respectively. Avoid contact with eyes, skin and clothing. Outside or detached storage is preferred.
Hazardous Decomposition Products: Carbon dioxide and carbon monoxide may form when heated to decomposition. This table shows how each list refers to the substance. When released into the air, this material may be moderately degraded by reaction with photochemically produced hydroxyl radicals. State and local disposal regulations may differ from federal disposal regulations. Use clean, non-sparking tools to collect absorbed material. Sur la composition de l'arome de cafe, Helv. Inhalation causes headache, fatigue, and drowsiness; high concentrations can produce central nervous system depression and optic nerve damage.
If vomiting occurs, keep head below hips to prevent aspiration into lungs. Do not use straight streams. Never give anything by mouth to an unconscious person. Please note that the latest information on the storage temperature for the products is described on our website. Chronic effects may be similar to those from methanol exposure because methyl acetate can be hydrolyzed yielding methanol and acetic acid. Containers of this material may be hazardous when empty since they retain product residues vapors, liquid ; observe all warnings and precautions listed for the product. Cool containers with flooding quantities of water until well after fire is out.
The main products are potassium sulphate, potassium nitrate, potassium hydroxide, caustic soda, sodium sulfide,sodium carbonate, annual production capacity is 6,000,000 tons. Where a mild odor, fast evaporating solvent is required, methyl acetate is a very good choice for formulators of coating and ink products. Store in a cool, dry well-ventilated location, away from any area where the fire hazard may be acute. Large amount of non-reacted methanol and acetic acid are recycled in the system, which complicates the separation process and requires large equipment investment and results in high energy consumption. Capillary chromatography of C1-C18 monochlorinated n-alkyl acetates, J. Capillary chromatography of C1-C18 monochlorinated n-alkyl acetates, J.
If symptoms such as wheezing, coughing, shortness of breath, or burning in the mouth, throat, or chest develop, call a physician and be prepared to transport the victim to a hospital. Capillary chromatography of C1-C18 monochlorinated n-alkyl acetates, J. Liquid irritates eyes and may cause defatting and cracking of skin. Companies make methyl acetate by heating methanol and acetic acid in the presence of sulfuric acid. Colleagues and friends eventually started suggesting that I make my data available on this website so that others could benefit from my efforts -- which I finally did in 2004.
