| titleOfInvention | Method for extracting indole in wash oil by using polyvinylpyrrolidone |
| abstract | The invention provides a method for extracting indole in wash oil by utilizing polyvinylpyrrolidone, which comprises the following steps: mixing polyvinylpyrrolidone with washing oil, stirring to make polyvinylpyrrolidone and washing oil perform solid-liquid adsorption, and performing solid-liquid adsorption after the solid-liquid adsorption is finished to obtain a de-indole washing oil phase and a polyvinylpyrrolidone phase. The method for extracting the indole from the wash oil by utilizing the polyvinylpyrrolidone uses the polyvinylpyrrolidone as the adsorbent, has the characteristics of no corrosivity and stable physical property, can better extract the indole from the wash oil by the operations of solid-liquid adsorption and solid-liquid separation after mixing the polyvinylpyrrolidone with the wash oil, and has the advantages of mild indole removal condition, simple process and easy large-scale production, wherein the indole removal rate can reach more than 93 percent. |
