A series of toxic products were produced after photocatalysis on ethanol, such as acetaldehyde, ethyl formate, ethyl acetate, diethoxymethane, 1,1-diethoxyethane.

如醇的反应产物包括醛，酸酯，酸甲酯，缩醛等一系列有害物。

Because of all these disvantages acetylchloride is used to react with absolute ethyl alcohol and synthesize ethyl acetate.

鉴于传统方法存在以上缺点,采酰氯代替酸作为原料,不使催化剂,不加热,常温反应来合成酸酯。
