Purification process |
| abstract |
The invention is for a process of removal of ionic contaminants from an organic solution. The process of the invention involves providing a mixed ion exchange resin modified by contact with an ammonium salt of a weak organic acid and contacting said organic solution with said modified exchange resin for a time sufficient to remove ionic impurities therefrom. The invention is useful for removal of ionic contaminants from organic solutions requiring high purity for use. |
