PRODUCTION OF LACTAMS BY AMMOXIMATIsN OF CYCLIC KETONES
摘要
<p>Present invention describes the direct catalytic liquid phase synthesis of caprolactam from cyclohexa- none, hydrogen peroxide and ammonia. The invention can be carried out by using mesoporous materials amongst the MMS family (mesoporous molecular sieves) as catalysts, such as Ti-MCM-41, Al-MCM-41 and Ti- SBA-15 materials as well as in the presence of zeolitic catalysts at temperatures between 20 and 120 C.</p>
