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 characteristics
Flammable 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
