| titleOfInvention | Industrial preparation method of high purity diol |
| abstract | The present invention uses dicyclic carbonate produced from the top of the column by using cyclic carbonate and aliphatic monohydric alcohol as a raw material, and supplying this raw material continuously in a continuous multi-stage distillation column A in which a catalyst is present. The low boiling point reaction mixture (A T ) containing the aliphatic monohydric alcohol is continuously extracted into the gas phase, and the high boiling point reaction mixture (A B ) containing the diols generated from the bottom of the column is continuously extracted into the liquid phase, and The high boiling point reaction mixture (A B ) is continuously supplied to the continuous multi-stage distillation column C, and the column bottom component (C B ) obtained by distilling off a substance having a lower boiling point than the diol is continuously supplied to the continuous multi-stage distillation column E having a specific structure, from a side cut extraction port provided on the lower portion of the chimney tray having a specified structure installed in the enrichment section, as a component of the liquid (S E) D The long-term high-purity diol in an amount of 1 or more per 1 ton provides a specific apparatus and method for stably producing the over (e. G., More than 1000 hours) by obtaining. |
