摘要
研究以二氯甲烷为萃取剂，利用汽相萃取由乙醛肟水溶液制备无水乙醛肟的工艺过程，所得乙醛肟贮存稳定性好，含量在９９％以上，收率达９３％。
The preparation of anhydrous acetaldoxime from an aqueous solution by gaseous extraction using methylene chloride as extracting agent was studied.The experimental result indicates that the product is provided with a good storage stability,its content being more than 99% and its yield more than 93%.
