| 摘要 |
The present invention relates to a process for purifying bisphenol-A by distillation thereof from a melt. So obtained melt of p,p-bisphenol-A exhibiting high thermal, color and storage stability is free of high-boiling components, is free of any surface-active components or of non-distilled metallic, salt, acid or polymeric components and it does not contain any components containing sulfur. O,p-BPA and phenol are separated and the low-boiling components are on the limit of being capable of demonstration.
