| titleOfInvention | A kind of method of separation of extractive distillation toluene and n-butanol mixture |
| abstract | The present invention relates to a kind of methods of separation of extractive distillation toluene and n-butanol mixture.This method is using dimethyl sulfoxide (DMSO) as extractant, it is introduced from extractive distillation column top, it is set to be come into full contact with the toluene and n-butanol mixture introduced in the middle part of extractive distillation column, after extracting rectifying, toluene is produced from the top of extractive distillation column, and extractant and n-butanol mixture enter extractant recovery tower from the bottom of extractive distillation column.After efficiently separating, n-butanol is produced from the top of extractant recovery tower, and extractant recycles after extractant recycling tower bottom extraction.This technique has the advantages that low energy consumption, simple for process, separation purity is high. |
