The invention pertains to an improved apparatus comprised of a monolith catalytic reactor having an inlet and an outlet and a static mixer having an inlet and an outlet thereto with the outlet of said static mixer in communication with the inlet of said monolith catalytic reactor. The invention also pertains to an improvement in a process for effecting a reaction in the monolith catalytic reactor wherein a reactant gas and reactant liquid are introduced to the inlet to the monolith catalytic reactor, reacted and, then, the reaction product passed through the outlet of the monolith catalytic reactor.

Monolith catalytic reactor coupled to static mixer

The present invention is directed to an improved reaction process that allows for the achievement of excellent NFproduction yields, while minimizing the amount of unreacted fluorine exiting with the process gases and minimizing the amount of liquid melt waste (HF/NH) produced by the process. The basic NFprocess resides in reacting Fwith an ammonium ion source, e.g., ammonium acid fluoride, under conditions for forming NF. The improvement in the process comprises:

Process for the production of nitrogen trifluoride

This invention relates to an improvement in a process for hydrogenating a nitroaromatic composition namely dinitrotoluene by contacting the dinitrotoluene with hydrogen in a reactor employing a monolith catalyst system. Broadly the improvement resides in the continuous, essentially solventless, adiabatic hydrogenation of dinitrotoluene to toluenediamine in a plug flow reactor system incorporating the monolith catalyst. The process generally comprises the steps: introducing a feedstock comprised of dinitrotoluene and reaction product components continuously into the reactor and said feedstock having less that 30% by weight of a solvent, carrying out the hydrogenation of dinitrotoluene to toluenediamine under adiabatic conditions; and, continuously removing hydrogenated reaction product from the reactor.
