| titleOfInvention | Enrichment and separation process of low-concentration multi-component phenol-containing mixture |
| abstract | The invention provides an enrichment and separation process of a low-concentration multi-component phenol-containing mixture, which sequentially comprises the following steps: the method comprises the steps of a 3, 5-dimethylphenol purification process, a 3, 4-dimethylphenol and m-cresol purification process, an isophorone purification process, an mesitylene and mesitylene purification process, wherein the 3, 5-dimethylphenol purification process comprises crystallization purification and decoloration rectification, the 3, 4-dimethylphenol and m-cresol purification process comprises alkalization phase separation, acidification phase separation, primary rectification and secondary rectification, the isophorone purification process comprises molecular distillation and vacuum rectification of reflux, and the mesitylene and mesitylene purification process comprises vacuum rectification of distillate. The method carries out efficient and clean deep treatment on a plurality of byproducts generated in the process of preparing the 3, 5-dimethylphenol by aromatizing the isophorone, can realize the maximization of the utilization rate of the raw materials, and has remarkable economic and social benefits. |
