Method for preparation of anion exchange resins |
| abstract |
An improved process for preparing anion exchange resins based on the usenof a non-agitated plug-flow quench procedure followed by recycle of a portion ofnthe recovered chloromethylation reaction fluids into subsequentnchloromethylation reactions is disclosed. The combination of plug-flownhydration, providing highly concentrated recovered sulfuric acid, together withnthe recycle or reuse of the recovered concentrated sulfuric acid, allows fornreduced raw material requirements during anion exchange resin manufacturenand reduces the environmental impact of waste sulfuric acid processing. |
