Process for reducing methanol in recycle stream in bisphenol-A production process |
| abstract |
By distilling the acetone-methanol-water containing mixture to recover acetone in the form of a relatively pure distillate at overhead and allowing a substantial portion of methanol and water to flow out with the base product, methanol is removed from the acetone recycle stream during bisphenol-A production. A method of removing to prevent deactivation of the catalyst is disclosed. |
