| titleOfInvention | A kind of method of comprehensive utilization of sodium hydrosulfite waste residue |
| abstract | The invention discloses a kind of method of comprehensive utilization of sodium hydrosulfite waste residue, (1) first adopts the method for underpressure distillation by the moisture removing in sodium hydrosulfite waste residue, can obtain ethylene glycol by underpressure distillation simultaneously; (2) complete for underpressure distillation remaining waste residue organic solvent is washed, obtain organic phase I and solid A; (3) according to solid different solubility in a solvent, sodium isethionate and sodium formiate can be obtained; (4) organic phase I is carried out vacuum distillation recovered solvent, can Thiodiglycol be obtained simultaneously.The waste residue produced in vat powder production process fully utilizes by the present invention, purifies and obtains four kinds of organic productss, brings economic benefit and social benefit while reducing enterprise's waste discharge to enterprise. |
