Apparatus for carrying out distillations and heterogeneously catalyzed reactions

An apparatus for carrying out distillations and heterogeneously catalyzed reactions, containing at least one segment which alternately superposed distillation and reaction trays (2) where DOLLAR A a) one or more of the reaction trays (2) a heterogeneous catalyst (9) and liquid comprise reaction zone containing the reaction zone is flowed through from bottom to top with liquid during the distillation, equipped DOLLAR a b) mentioned in a) reaction trays (2) with a filling and emptying means for heterogeneous catalyst (9) which is arranged to is are, and DOLLAR a c) in each case at least one outlet for the transport of liquid between said in a) reaction trays (2) and the jweils next lower distillation trays arranged. DOLLAR A The inventive apparatus is preferably used for the reactive distillation.
