Water spray may reduce vapor, but may not prevent ignition in closed spaces. If breathing is difficult, give oxygen. Cool containers with flooding quantities of water until well after fire is out. The reaction of methyl acetate and a base, for example sodium hydroxide, is a second-order reaction with respect to both reactants. In the traditional process, one reactor and nine distillation columns are required to produce high purity methyl acetate.
Industrial companies can make methyl acetate from methanol and carbon monoxide. Actuators B, 69, 2000, 253-257. Liquid irritates eyes and may cause defatting and cracking of skin. If breathing is difficult, give oxygen. To view more metadata about the specific Synonym, click on the Synonym. The main products are potassium sulphate, potassium nitrate, potassium hydroxide, caustic soda, sodium sulfide,sodium carbonate, annual production capacity is 6,000,000 tons.
For massive fire, use unmanned hose holders or monitor nozzles; if this is impossible, withdraw from area and let fire burn. Environmental Toxicity: This material is not expected to be toxic to aquatic life. Sur la composition de l'arome de cafe, Helv. The reaction conditions are moderate, however, as methyl acetate, methanol and water will form binary and tertiary azeotropic mixtures, it is very difficult to prepare high purity product by conventional methods. Aggravation of Pre-existing Conditions: Persons with pre-existing skin disorders, eye problems, impaired respiratory function or central nervous system conditions may be more susceptible to the effects of this substance. 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.
Volatile chemicals have a high risk of being aspirated into the victim's lungs during vomiting which increases the medical problems. The retention behaviour of pyruvate esters and related carbonyl and carboxyl compounds, J. Other symptoms expected to parallel inhalation. It integrates the reaction and separation, i. Extremely flammable - readily forms explosive mixtureswith air. Companies make methyl acetate by heating methanol and acetic acid in the presence of sulfuric acid. Wear appropriate personal protective equipment as specified in Section 8.
Capillary chromatography of C1-C18 monochlorinated n-alkyl acetates, J. Because of its fast evaporation rate, methyl acetate is useful as the fast-evaporating component in high-low solvent systems and in other applications where fast solvent release and quick dry-to-touch time are needed. Thirtieth Anniversary of the Retention Index According to Kovats in Gas-Liquid Chromatography, J. As a solvent, methyl acetate is usually mixed with acetone and methyl alcohol. To resolve this problem, over the years, I compiled chemical names and identifiers into a personal database, cross referencing regulatory and health safety information when possible. Explosion: Above flash point, vapor-air mixtures are explosive within flammable limits noted above.
Structure-retention increments of aliphatic esters, J. Methyl acetate is occasionally used as a solvent, being weakly polar and lipophilic, but its close relative ethyl acetate is a more common solvent being less toxic and less soluble in water. Ecological Information Environmental Fate: When released into the soil, this material may leach into groundwater. Nova, 30 8 , 2007, 2031-2034. When released into the air, this material may be removed from the atmosphere to a moderate extent by wet deposition.
Methyl acetate is an active solvent for the following resins: cellulose acetate butyrate, nitrocellulose, vinyl copolymers, acrylics, epoxies, polyamides, phenolics, alkyds, and polyesters. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. This material is not expected to significantly bioaccumulate. Eye Contact: Immediately flush eyes with plenty of water for at least 15 minutes, lifting upper and lower eyelids occasionally. Methyl acetate is a byproduct of making acetic acid. Part I: freshly-squeezed juice, Flavour Fragr. Remove contaminated clothing and shoes.
Because of its fast evaporation rate, methyl acetate is useful as the fast-evaporating component in high-low solvent systems and in other applications where fast solvent release and quick dry-to-touch time are needed. Conditions to Avoid: Heat, flames, ignition sources and incompatibles. If eye irritation persists: Get medical advice or attention. Chronic Exposure: Repeated contact with the liquid may cause dryness, cracking, and skin irritation. Capillary column studies of alkyl acetates, chloroacetates, dichloroacetates and trichloroacetates, J. Transport Information Domestic Land, D.

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. Provide proper respiratory protection to rescuers entering an unknown atmosphere. If vomiting occurs, keep head below hips to prevent aspiration into lungs. Methyl Acetate Methyl acetate is a flammable liquid that smells similar to nail polish remover or glue.
Use clean, non-sparking tools to collect absorbed material. Take precautionary measures against static discharge. Thoroughly clean shoes before reuse. Methyl acetate has a solubility of 25% in water at room temperature. When released into the soil, this material is expected to quickly evaporate. Avoid contact with eyes, skin and clothing. Withdraw immediately in case of rising sound from venting safety devices or discoloration of tank.
