PREPARATION OF POLYOXYALKYLENE-ALPHA,OMEGA-DICARBOXYLIC ACIDS |
| 摘要 |
A process for the preparation of a polyoxyalkylene-alpha,omega-dicarboxylic acid by reacting the corresponding polyoxyalkylene glycol with a stable free radical nitroxide in the presence of a NOx-generating compound and optionally, an oxidant and/or a solvent, at a temperature in the range of from 0 DEG C to 100 DEG C and thereafter separating out the polyoxyalkylene-alpha,omega-dicarboxylic acid. |
