Removal of guaiacol from cresylic acid feedstreams by heating with a strong acid |
摘要 |
A process is described for the removal of guaiacol from naturally occurring cresylic acid feed by heating the feed with a strong acid, particularly hydrochloric acid or sulfuric acid, to produce a purified cresylic acid product essentially free of guaiacol and other methoxy aromatic compounds without significant loss of cresylic acid product.
