摘要： As starting materials and the aliphatic monohydric alcohol and a cyclic
carbonate, carrying out the reaction distillation by continuously feeding the continuous multi-stage distillation column A in the prence of a catalyst to the raw material, the
prent invention, dialkyl carbonate is produced from upper portion of the column The continuously withdrawn in a gaous form a low boiling point reaction mixture containing the aliphatic monohydric alcohol (A then continuously extracted in liquid form (A a high boiling point reaction mixture containing the diol is produced from lower portion of the column, Continuous having a specific structure and (C column bottom component is continuously supplied to a continuous multi-stage distillation column C the high boiling point reaction mixture (A is obtained by evaporating the material of the lower boiling point than the diol From withdrawal outlet side cut placed at the bottom of the chimney tray having a specific structure which is continuously supplied to a multi-stage distillation column E, is installed in the enrichment ction, to obtain the diol as (E component of the liquid by an amount of more than 1 ton per hour, to a method and a specific apparatus (for example, 1000 hours or more) can be produced stably for a long time a high-purity diol.
