    摘要： A process for industrially producing dialkyl carbonate and a diol continuously through a reactive distillation system is disclosed. The process includes the steps of taking a cyclic carbonate and an aliphatic monohydric alcohol as starting materials, continuously feeding the starting materials into a continuous multi-stage distillation column in which a catalyst is present, carrying out reaction and distillation simultaneously in the column, continuously withdrawing a low boiling point reaction mixture containing the produced dialkyl carbonate from an upper portion of the column in a gaseous form, and continuously withdrawing a high boiling point reaction mixture containing the diol from a lower portion of the column in a liquid form. According to the present invention, there is provided a specific continuous multi-stage distillation column having a specified structure, and a production process using this continuous multi-stage distillation column.

    摘要： It is an object of the present invention to provide a specific apparatus and process for industrially producing a high-purity diol by taking a cyclic carbonate and an aliphatic monohydric alcohol as starting materials. Moreover, it is an object to thus provide a specific industrial apparatus and industrial production process that are inexpensive and, for example, enable the high-purity diol to be produced in an amount of not less than 1 ton/hr, preferably not less than 2 tons/hr, more preferably not less than 3 tons/hr, stably for a prolonged period of time (e.g. not less than 1000 hours, preferably not less than 3000 hours, more preferably not less than 5000 hours). According to the present invention, the above objects can be attained by using a continuous multi-stage distillation column A, a continuous multi-stage distillation column C, and a continuous multi-stage distillation column E, which have a specified structure, and withdrawing a liquid component from the side cut outlet, which is installed at the bottom of a chimney tray having a specified structure installed in an enrichment section of the continuous multi-stage distillation column E.
