Purification of acetic acid from wood acetylation process |
| abstract |
A method of purifying acetic acid containing terpene and terpenoid impurities, includes: (a) supplying acetic acid containing terpene or terpenoid impurities and water to a distillation column; (b) azeotropically removing terpene or terpenoid impurities from the mixture of acetic acid and water supplied to the column as distillate; and (c) withdrawing a product stream from the column comprising acetic acid purified of terpene or terpenoid impurities. The method is particularly effective for purifying acetic acid recovered from a wood purification process. |
