D 8521 A b s t r a c t A discontinuous process for conducting a heterogeneously catalyzed reaction and a plant for the heterogeneously catalyzed production of products The invention relates firstly to a discontinuous process for conducting a heterogeneously catalyzed reaction taking place at elevated temperature, in which heat-sensi- tive products are formed, a heat transfer unit (4) dif- ferent from the reactor (1) being used for heating and a fixed-bed catalyst (3) being used as the catalyst and the reaction mixture being continuously circulated in succes- sion through the catalyst (3) and then through the heat transfer unit (4). The problem to be solved in this process is to avoid losses of catalyst and product and to shorten the batch time and, optionally, the reaction time in accordance with German patent applications P 38 13 612.0 and P 38 26 320.3. The invention also relates to a plant for the dis- continuous heterogeneously catalyzed production of heat- sensitive products at elevated temperature comprising a reactor (1), characterized by a heat transfer unit (4) arranged outside and connected to the reactor (1), a catalyst container (3) containing a fixed-bed catalyst preceding the heat transfer unit and a pump (2) for con- tinuously circulating the reaction mixture in succession through the catalyst (3) and then through the heat transfer unit (4).
