Method for purifying phenol |
| abstract |
The present invention provides a phenol stream comprising hydroxy acetone, 2-methylbenzofuran, 3-methylbenzofuran and phenol in contact with acyl chloride in the presence of organic sulfonic acid to react hydroxy acetone, 2-methylbenzofuran and 3-methylbenzo. Converting at least one selected from the group consisting of furans into a high boiling point compound having a higher boiling point than the phenol; And recovering the high boiling point compound from the phenol stream. |
