METHOD TO PREPARE NONYLATED DIPHENYLAMINE USING RECYCLE AND SEQUENTIAL TEMPERATURES |
摘要 |
<p>The present invention relates to a process for preparing nonylated diphenylamines which improves nonene usage by recycling and reusing stripped nonene from an earlier process. The process comprising consecutive recycle of recovered nonene is conducted at a sequential two step temperature reaction, namely a more severe temperature followed by a lower temperature. The product prepared by this process is a useful antioxidant for lubricating oil compositions.</p> |
