Process for conducting liquid/liquid multiphase reactions in a tubular reactor having static mixing elements separated by coalescing zones

A tubular reactor characterized by having short static mixing elements separated by coalescing zones is used to conduct multiphase liquid/liquid reactions. Small droplets of one of the phases are dispersed into the other phase by the static mixing elements. These droplets coalesce and at least parti...

Summary:A tubular reactor characterized by having short static mixing elements separated by coalescing zones is used to conduct multiphase liquid/liquid reactions. Small droplets of one of the phases are dispersed into the other phase by the static mixing elements. These droplets coalesce and at least partially phase separate as the mixture passes through the subsequent coalescing zone. The tubular reactor is particularly suitable for nitrating organic compounds while forming low levels of improperly nitrated by-products and low levels of nitrophenolics.
