| titleOfInvention | A method for enriching organochlorine in waste lubricating oil |
| abstract | The invention provides a method for enriching organic chlorine in waste lubricating oil, belonging to the field of waste lubricating oil recycling. It solves the problem that the existing gas chromatography-mass spectrometry cannot determine the form of organic chlorine. A method for enriching organic chlorine in waste lubricating oil includes the following steps: S01: dehydrating the waste lubricating oil, and then reducing the waste lubricating oil. Pressure distillation, collecting distillate oil at 250-400°C; S02: complexing distillate oil with complexing agent; S03: adding inorganic lye, first adjusting the pH of the solution between 7-8, and then adjusting the pH of the solution to 9 Between -11; S04: add organic solvent to extract, obtain oily phase; Described complexing agent is the polar complexing agent containing Lewis acid. The invention has the advantages of effectively enriching chlorine-containing compounds in waste lubricating oil and the like. |
