Patent number: 9382195Abstract: The present disclosure provides methods for separating ketones and alcohols. In one embodiment, the methods and compositions disclosed are useful in separating cyclohexanol from cyclohexanone. In one embodiment, cyclohexanone is converted to its corresponding oxime by treating the cyclohexanone with hydroxylamine. The resulting cyclohexanone oxime is then separated from the cyclohexanol, providing streams of cyclohexanol and cyclohexanone oxime.Type: GrantFiled: March 11, 2014Date of Patent: July 5, 2016Assignee: Honeywell International Inc.Inventors: James A. Kweeder, Alan B Levy
