Abstract
Systems disclosed herein may include at least one high shear mixing device configured to produce a dispersion of oxygen-containing gas bubbles in toluene liquid phase, wherein the dispersion has a mean bubble diameter of less than 5 microns; a pump configured to deliver a liquid stream comprising the toluene to the high shear mixing device; and a vessel configured to receive the dispersion from the high shear mixing device and configured to maintain a predetermined pressure and temperature.
Claims20
A system for reaction of toluene, the system comprising;
- at least one high shear mixing device configured to produce a dispersion of oxygen-containing gas bubbles in toluene liquid phase, wherein the dispersion has a mean bubble diameter of less than 1 micron;
- a pump configured to deliver a liquid stream comprising the toluene to the high shear mixing device;
- and
- a vessel configured to receive the dispersion from the high shear mixing device and configured to maintain a predetermined pressure and temperature.
A system for production of benzoic acid, the system comprising;
- at least one high shear mixing device configured to produce a dispersion of oxygen-containing gas bubbles in a toluene liquid phase or a xylene liquid phase, wherein the high shear device comprises a rotor and a stator, and wherein the dispersion has a mean bubble diameter of less than 5 microns;
- a pump configured for delivering a liquid stream comprising the toluene or the xylene to the high shear mixing device;
- and
- a vessel configured to receive the dispersion from the high shear mixing device and configured to maintain a predetermined pressure and a temperature than about 160° C.
