    Abstract: 1315504 Catalytic process BADISCHE ANILIN- & SODA-FABRIK AG 14 Aug 1970 [16 Aug 1969] 39195/70 Heading B1F A process for carrying out an exothermic reaction between a -gas and a liquid, in the presence of a solid catalyst, in which hot spots and therefore the formation of byproducts are prevented, comprises passing the gas and liquid concurrently downwardly through a catalystcontaining reaction vessel thereby causing a pressure difference #P to be set up between the ends of the reaction vessel, the rate of flow, F, of liquid through the reaction vessel being at such a value t that, at constant gas flow, the change of pressure difference #P with respect to changes in liquid flow rate, i.e. d(#)p/dF is at least twice as great when F equals t as when F equals L, L being a liquid flow rate which causes at least predominantly laminar flow of the liquid through the reaction vessel, the value t not being great enough to cause pulsing of pressure difference #P.
