Beschreibung
Zusammenfassung:	The invention provides a preparation method of ketoxime and/or aldoxime. The method includes a step of performing an ammoximation reaction to ketone and/or aldehyde, ammonia and hydrogen peroxide at 50-200 DEG C in a water solution in the presence of an oximation catalyst without any organic solvent. The method has high conversion rate of ketone and/or aldehyde and high selectivity of ketoxime and/or aldoxime, is simple in subsequent separation and purification, and has great industrial application prospect. 本发明提供了种酮肟和/或醛肟的制备方法，该方法包括在肟化催化剂的存在下且在无任何有机溶剂的条件下，将酮和/或醛、氨和过氧化氢在水溶液中进行氨肟化反应，且所述氨肟化反应的温度为50-200℃。采用本发明提供的方法能够获得较高的酮和/或醛的转化率以及酮肟和/或醛肟的选择性，而且后续分离提纯简单，极具工业应用前景。
