Preparation of ethyl acetate - Chemistry Online
2024年4月22日 · Laboratory experiment of the preparation of ethyl acetate (ester) by Fischer reaction between acetic acid and ethyl alcohol.
由于酯化反应是可逆反应,为提高酯的产率,采用增加乙醇的用量以及不断将产物乙酸乙酯和水蒸出的措施,使平衡右移。 反应中,浓硫酸除起催化作用外,还吸收反应生成的水,有利于酯的生成。 温度计浸入液面,但注意不能太低,以防被搅拌子打碎! 在100 mL 三口瓶中加入9.5 g (12 mL)无水乙醇,搅拌下缓慢加入12 mL浓硫酸(冰浴)。 12.6 g (12 mL)冰醋酸的混合液。 先滴加3-4...
Ethyl acetate synthesis by direct addition of acetic acid to …
2022年9月25日 · Therefore, the present work aims at a detailed experimental kinetic study of the ethyl acetate synthesis by direct addition of AcOH to C 2 H 4 on a commercial STA catalyst. Focus is given to the ethylene and acetic acid conversions as well as the selectivities and yields to the main products (ethyl acetate, ethanol and diethyl ether) as a ...
Synthesis of Ethyl Acetate - Alfa Chemistry
The dried crude ethyl acetate was filtered into a 50mL distillation bottle and distilled in a water bath to collect 73℃~78℃ fractions. Ethyl acetate can form a binary or ternary azeotrope with water and ethanol. The boiling point and composition are shown in Table 1.

Towards a Green Process for Bulk‐Scale Synthesis of Ethyl Acetate ...
2012年4月19日 · Green is a go: An efficient acceptorless dehydrogenative dimerization of ethanol to give ethyl acetate was realized (see scheme). The reaction proceeds under mild reaction conditions in the presence of a ruthenium catalyst with concomitant liberation of molecular hydrogen, which can be used as a valuable product itself.
