| titleOfInvention | A kind of method reclaiming useful component in careless ammonium phosphine production process mixing solvent slop |
| abstract | The invention discloses a kind of adopt integrated rectification process reclaim careless ammonium phosphine production process produce mixing solvent slop in tetrahydrofuran (THF), methylisothiouronium methylphosphite diethyl ester, triethyl-phosphite, the method of the useful components such as trimethylbenzene, the integrated rectification process of single tower distillation is connect after adopting the rectifying of single tower lateral line discharging, from the direct extraction tetrahydrofuran (THF) of side line rectifying tower tower top, tower reactor obtains trimethylbenzene, simultaneously from the mixed solution of side take-off methylisothiouronium methylphosphite diethyl ester and triethyl-phosphite, send into rectifying tower and carry out single tower separation, tower top obtains methylisothiouronium methylphosphite diethyl ester, tower reactor obtains triethyl-phosphite.The inventive method adopts integrated rectification process to reclaim useful component in careless ammonium phosphine production process mixing solvent slop, and the overall rate of recovery of mixed solvent is more than 98%, and quality all reaches the standard of reusing.The present invention is compared with three conventional tower conventional distillation methods, and equipment cost and energy consumption all obviously reduce. |
