CAS.141-78-6 Pure Acetic Acid Ethyl Ester
Physical propertyAppearance: colorless, clear and sticky liquid.Aroma: there is a strong smell of ether like, Qing Ling, fruity bouquet to microstrip, diffusion, not lasting.Combustion: flammableFlash point (c):-4 (closed cup), 7.2 degrees (open cup)Ignition temperature (c):426Lower explosion limit (%):2.0Upper limit of explosion (%):11Explosion limit: 2.2% - 11.2% (volume) [1]Minimum ignition energy (mJ):0.46Maximum explosion pressure (MPa):0.850Polarity: 4.30Viscosity: 0.45Boiling point: 77.2Absorption wavelength: 260Melting point: -83.6[1]Relative density (air =1):3.04Relative density (water =1):0.90Critical temperature: 250.1Melting point (c):-83.6The refractive index (20 C):1.3708 1.3730Relative density (water =1):0.894- - 0.898Relative vapor density (air =1):3.04Saturated vapor pressure (kPa):13.33 (27 C)Combustion heat (kJ/mol):2247.89Critical temperature (c):250.1Critical pressure (MPa):3.83Octanol / water partition coefficient of value: 0.73Molecular dipole moment at room temperature: 1.78DSolubility: slightly soluble in water, soluble in alcohol, ketone, ether, chloroform and other organic solvents.Ethyl acetate and ethyl acetate. pure ethyl acetate is a colorless transparent liquid with pungent odor, is widely used as a kind of fine chemical products, with excellent solubility, quick drying, wide use, is a very important organic chemical raw materials and excellent industrial solvent, is widely used for cellulose acetate, ethyl cellulose, chlorinated rubber, vinyl resin, synthetic rubber, cellulose acetate resin, paint and paint production process. We said wine is good to drink, because alcohol containing ethyl acetate. Ethyl acetate with fruit flavor. Because wine contains a small amount of acetic acid, ethyl acetate and ethanol formation reaction. Because this is a reversible reaction and slow reaction, so it has a long time, will lead to the accumulation of ethyl acetate wine aroma. 1, as an industrial solvent for paints, adhesives, ethyl cellulose, artificial leather, linoleum colorant, man-made fiber and other products. 2, as a binder for ink printing, the production of artificial pearls. 3, as the extraction agent, used in medicine, organic acids, etc. products production.Risk characteristicsFlammable vapor and air can form explosive mixtures. In case of fire, high fever can cause combustion and explosion. And oxidant exposure will react violently. In the fire, the heated container with explosion danger. The vapor is heavier than air, to the lower spread of quite far from the local, in case of fire will burn the back
