    摘要： The invention relates to a process for the continuous manufacture of trioxan, if appropriate together with cyclic formals, from aqueous formaldehyde solutions in a circulation reactor with an evaporator, wherein the vapor/liquid mixture, before it enters the reactor, is separated into the vapor phase and the liquid phase, and subsequently the two phases are fed separately to the reactor. In particular, high space-time yields can be achieved by the process according to the invention. Moreover, equipment for carrying out this process is a subject of the invention.

    摘要翻译： 本发明涉及一种在具有蒸发器的循环反应器中连续制备三恶烷（如果合适的话）与循环形式的甲醛水溶液的连续制备方法，其中蒸气/液体混合物在其进入反应器之前被分离成蒸气 相和液相，随后两相分别进料到反应器中。 特别地，通过根据本发明的方法可以实现高的时空产率。 此外，用于执行该过程的设备是本发明的主题。
