Patent ID: 8153077

Claim:
A system for production of nitrobenzene, the system comprising: at least one high shear mixing device configured for producing a nanoemulsion comprising benzene-containing particles dispersed in a mixture of concentrated nitric acid and concentrated sulfuric acid, wherein said particles have a mean diameter of less than 1 micron; a pump configured for delivering a pressurized liquid stream comprising a mixture of concentrated nitric acid and concentrated sulfuric acid and benzene to said at least one high shear mixing device; and a vessel configured for receiving said nanoemulsion from said at least one high shear mixing device, wherein the vessel comprises an inlet for the nano emulsion, a gas outlet configured for removal of gas from the vessel, an outlet for a reaction product comprising nitrobenzene and an outlet line fluidly connecting the vessel with the at least one high shear mixing device whereby material may be transferred from the vessel to the at least one high shear mixing device.
