    • A process for preparing tolylenediamine by hydrogenating dinitrotoluene with hydrogen in the presence of a suspended catalyst in a vertically upright reactor (1), at the upper end of which is arranged a motive jet nozzle (2) through which the reaction mixture drawn off from the reactor bottom, via an external loop, is sprayed into the upper region of the reactor (1) and then flows into a central inserted tube (4) which is arranged in the longitudinal direction of the reactor, flows through the latter from the top downward and flows upward again outside the inserted tube (4) in an internal loop motion, with a heat exchanger (6) in the interior of the reactor (1), through which cooling water flows, and absorbs some of the heat of reaction as it does so, with a feed for the dinitrotoluene at the upper end of the reactor (1) and a feed for the hydrogen at the lower end of the reactor (1), and wherein, in addition to the heat exchanger (6) arranged in the interior of the reactor (1), a further heat exchanger (W) is used in the external loop, in which water absorbs the rest of the heat of reaction by indirect heat exchange with the reaction mixture, which comprises utilizing the heat of reaction to raise steam with a pressure of at least 4 bar gauge by performing the hydrogenation of dinitrotoluene to tolylenediamine at a temperature of ≧180° C.

    • The invention relates to a process for producing a catalyst for gas-phase oxidations, which comprises weighing a particulate inert support having a total mass of Msupport into a fluidized-bed apparatus, providing an aqueous suspension of a catalytically active material or sources therefor and a binder having a binder content of Bsusp, fluidizing the inert support by introduction of a gas stream heated to a temperature of Tgas at a flow rate of Qgas, and spraying the suspension at a rate of Qsusp onto the fluidized inert support. When Qgas, Qsusp, Bsusp, Msupport and Tgas are selected within the ranges 3000≦Qgas [m3/h]≦9000, 1000≦Qsusp [g/min]≦3500, 2≦Bsusp [% by weight]≦18, 60≦Msupport [kg]≦240. 75≦Tgas [° C.]≦120 so that a parameter K defined as K=0.020 Qgas−0.055 Qsusp+7.500 Bsusp−0.667 Msupport+2.069 Tgas−7satisfies the relationship 127.5≦K≦202, high-quality coatings can be produced and the formation of twins made up of support particles adhering to one another can be avoided.
