At room temperature, methyl acetate is a colorless liquid with a fragrant odor. 141-78-6 Revision Date 2007-03-01 California Prop. It is also prepared in industry using the Tishchenko reaction, by combining two equivalents of acetaldehyde in the presence of an alkoxide catalyst: Silicotungstic acid is used to manufacture ethyl acetate by the alkylation of acetic acid by ethylene:[8]. Ethyl acetate is used primarily as a solvent and diluent, being favored because of its low cost, low toxicity, and agreeable odor. Methyl acetate is only occasionally used as a solvent. Hot melt adhesives (such as hot glue sticks) and top-of-the line soccer cleats are usually made from EVA, generally with additives like wax and resin. Ethyl acetate is the ester of ethanol and acetic acid; it is manufactured on a large scale for use as a solvent. [5]) Chemsrc provides ethyl acetate(CAS#:141-78-6) MSDS, density, melting point, boiling point, structure, formula, molecular weight etc. 2. 2. Guidechem provides Ethyl acetate chemical database query, including CAS registy number 141-78-6, Ethyl acetate MSDS (Material Safety Data Sheet), nature, English name, manufacturer, function/use, molecular weight, density, boiling point, melting point, structural formula, etc. This mixture converts to the ester in about 65% yield at room temperature: The reaction can be accelerated by acid catalysis and the equilibrium can be shifted to the right by removal of water. Ethyl acetate (systematically ethyl ethanoate, commonly abbreviated EtOAc, ETAC or EA) is the organic compound with the formula CH 3−COO−CH 2−CH 3, simplified to C 4H 8O 2.

It is a flammable liquid and is an irritant. At room temperature, methyl acetate is poorly water soluble. MATERIAL SAFETY DATA SHEET(MSDS)- ETHYL ACETATE 1. In recent years, EVA foam has seen popular use in cosplay communities, largely in part due to its ease to work with, durability, and comfort in comparison to traditional plastic-based costumes. [4], Ethyl acetate was first synthesised by Count de Lauraguais in 1759 by distilling a mixture of ethanol and acetic acid. It is also used in the photovoltaics industry as an encapsulation material for crystalline silicon solar cells in the manufacture of photovoltaic modules. Both Methyl acetate and ethyl acetate are organic compounds with closely related chemical and physical properties. Storage tank Finally prepared ethyl acetate is stored into this tank. Supervision conditions:AB(certificate of inspection for goods inward,certificate of inspection for goods outward). 1. Buying Leads | Ethyl acetate is synthesized in industry mainly via the classic Fischer esterification reaction of ethanol and acetic acid. EVA can easily be cut from sheets and molded to shape. The molar mass of the compound is 74 g/mol. It is used as a cold flow improver for diesel fuel and as a separator in HEPA filters. [10] It is also used in paints as an activator or hardener. Ethyl acetate is the most common ester in wine, being the product of the most common volatile organic acid – acetic acid, and the ethyl alcohol generated during the fermentation. [9] For example, it is commonly used to clean circuit boards and in some nail varnish removers (acetone is also used). There are three different types of EVA copolymer, which differ in the vinyl acetate (VA) content and the way the materials are used. Stable. Furthermore, Ethyl acetate is the ester of ethanol and acetic acid. EVA copolymers are adhesives used in packaging, textile, bookbinding for bonding plastic films, metal surfaces, coated paper and as redispersible powders in plasters and cement renders. The weight percent of vinyl acetate usually varies from 10 to 40%, with the remainder being ethylene. In rare cases exposure may cause sensitization of the mucous membrane and eruptions of the skin. MSDS/SDS Database Search | The drug-filler-polymer mixture is then cast into a mold at −80 °C and freeze-dried until solid. 1. New Window. These devices are used in drug delivery research to slowly release a compound. This reaction gives ethanol and sodium acetate, which is unreactive toward ethanol: Under anhydrous conditions, strong bases induce the Claisen condensation to give ethyl acetoacetate:[12]. It is also used to make thermoplastic mouthguards that soften in boiling water for a user-specific fit. [7] Ethyl Acetate CAS RN: 141-78-6 Melting Point-83.8 deg C. CRC Handbook of Chemistry and Physics 94th Edition. This liquid is also widely used as a solvent. Acetate is an anion derived from the acetic acid (removal of the hydrogen atom in the carboxylic acid group forms the acetate anion). [11] Ethyl acetate is rarely selected as a reaction solvent because it is prone to hydrolysis, transesterification, and condensations. Given that the chemical is naturally present in many organisms, there is little risk of toxicity. The melting point of methyl acetate is -98°C while the boiling point is 56.9°C. 141-78-6 Revision Date 2007-03-01 Pennsylvania Right To Know Components Ethyl acetate CAS-No. Coffee beans and tea leaves are decaffeinated with this solvent. The key difference between methyl acetate and ethyl acetate is that methyl acetate has a methyl group attached to an acetate group whereas ethyl acetate has an ethyl group attached to an acetate group. Glucose and glycerol concentrations and their tracer enrichment measurements using liquid chromatography tandem mass spectrometry. Service | EVA is an elastomeric polymer that produces materials which are "rubber-like" in softness and flexibility.
