| titleOfInvention | Process for the purification of a cresylic acid mixture contaminated by neutral oils and / or tar bases |
| abstract | Process for the purification of a cresylic acid mixture contaminated by neutral oils and / or tar bases, in which the neutral oils and / or tar bases are separated by extractive distillation using a high-boiling solvent from the Kresylsäuremischung and withdrawn at the top of an extractive distillation column and the solvent is separated by distillation from the purified cresylic acid mixture and recycled to the extractive distillation column, wherein the cresylic acid mixture consists of a broad phenol-containing boiling cut, characterized in that a higher-boiling fraction of the contaminated cresylic acid mixture and a lower-boiling fraction of the contaminated cresylic acid mixture are fed in separate feed streams to the extractive distillation column, wherein the lower-boiling fraction is fed below the higher-boiling fraction , |
