ethyl acetate chemical formula thiab qauv
ethyl acetate EA yog dab tsi?
Cov qauv tshuaj ntawm ethyl acetate yog CH₃COOCH₂CH₃, suav nrog pawg acetyl (CH₃CO–) thiab pawg ethoxy (–OCH₂CH₃) txuas los ntawm ester daim ntawv cog lus. Nws lub cev muaj zog suav nrog qhov kub ntawm 77.1℃thiab qhov ceev ntawm 0.902 g / cm³. Nws yog volatile, muaj ib tug fruity tsw, yog me ntsis soluble nyob rau hauv dej, thiab yooj yim soluble nyob rau hauv organic solvents.
Ethyl acetate feem ntau yog siv los ua cov kuab tshuaj, khoom noj khoom haus - qib flavoring agent, thiab tus neeg saib xyuas / degreasing.
