Abstract

Oximes are produced by treating aldehydes or ketones with aqueous hydroxylamine salt solution in two stages leaving excess of hydroxylamine salt at the finish, preferably in a cyclic process, in a range of pH of 1.5-4.5. In examples, cyclohexanone cyclopentanone, and cycloheptanone are converted to oximes. The process is applicable to aldehydes and ketones having oximes difficulty soluble in water.
