Harmless disposal recovery method for glufosinate-ammonium process byproduct ethyl acetate coarse product

The invention provides a harmless disposal recovery method for a glufosinate-ammonium process byproduct ethyl acetate coarse product. The method comprises the following steps: adding alkali into the byproduct ethyl acetate coarse product at 0-25 DEG C to obtain a mixture and then stirring the mixture for 3-5 hours at 0-77 DEG C; and after reaction, distilling the mixture to obtain the mixture of ethyl acetate and ethanol. The method provided by the invention obtains ethyl acetate from an industrial byproduct ethyl acetate coarse product with a relatively high recovery rate, removes harmless substances such as acrolein and acetic acid in the coarse product, avoids the safety risk of recycling the obtained ethyl acetate as an industrial solvent, improves the safe disposal scheme of byproducts in the glufosinate-ammonium industrial development process and meets the development direction of green chemical industry. 本发明提供种草铵膦工艺副产物乙酸乙酯粗品的无害化处理回收方法，包括以下步骤：在0～25℃下，向副产物乙酸乙酯粗品中加入碱，得到混合物，然后在0～77℃的条件下搅拌混合物3～5h；反应结束后蒸馏，得到
