Ethyl acetate (ethyl acetate), also known as ethyl acetate, chemical formula is C4H8O2, molecular weight is 88.11, it is an ester with functional group -COOR (a double bond between carbon and oxygen), which can undergo alcoholysis and aminolysis Common reactions of general esters such as transesterification and reduction. Low toxicity, sweet taste, pungent odor when the concentration is high, volatile, excellent solubility, quick-drying, widely used, is an important organic chemical raw material and industrial solvent. It is a Class I flammable product and should be stored in a low-temperature ventilated place, away from fire sources. In the laboratory, it is generally prepared by the esterification of acetic acid and ethanol.
