Verfahren zur Spaltung von Tertiärbutylalkohol in einer Reaktionsdestillationskolonne

摘要

Cleaving tert. butyl alcohol in a reaction distillation column comprises: (a) carrying out the reaction on an acidic ion exchange resin as catalyst arranged above the sump; (b) partially condensing the top product of the column in a dephlegmator, which is connected to the head of the column; and (c) adding a part of the liq. educt-rich distillate from the dephlegmator to the column head as a recycled part. An appts. is also claimed for carrying out the process and comprises coupling the head of the head to the dephlegmator.
