Abstract
A nitration reactor () incorporating sections of downward flow for use in preparing nitrated organic compounds. It comprises a first vertically-oriented reactor section (), a second vertically-oriented reactor section (), a connecting section () between the two reactor sections, one or more inlets () for introducing nitration reactants into the reactor, an outlet () for the removal of nitration reaction products, a vertically-downward flowpath () for the nitration reactants in one of the reactor sections or the connecting section, and operating conditions that produce a flow regime in the vertically-downward flowpath that is a dispersed flow regime or a bubbly flow regime. The invention overcomes the limitations of prior art nitration reactors of the type in which fluids flow largely in a vertically upward direction, with respect to hydrostatic demands and plant layout considerations.
