| titleOfInvention | Refining method of m-cresol and p-cresol |
| abstract | The invention provides a refining method of m-cresol and p-cresol, which comprises the steps of firstly introducing crude m-cresol and p-cresol into a lightness-removing tower, rectifying the crude m-cresol and p-cresol to obtain high-purity 2, 6-xylenol, then introducing the high-purity 2, 6-xylenol into a weight-removing tower, and rectifying to obtain high-purity o-ethylphenol and m-cresol. In the invention, the refining of the 2, 6-xylenol and the o-ethylphenol can be realized at one time in the m-p-cresol refining process by continuously rectifying the crude m-p-cresol for two times and matching with the specific temperature, pressure and reflux ratio, and the high-purity o-ethylphenol, 2, 6-xylenol and m-p-cresol are obtained simultaneously. |
