This report supplements previous reports on the subject of aromatic amines. The report includes updated preliminary process designs and estimated economics for the manufacture of nitrobenzene by nitration of benzene, by the conventional process and an adiabatic nitration process; the manufacture of aniline by hydrogen reduction of nitrobenzene; and the manufacture of aniline by ammonolysis of phenol. We have also presented a preliminary process design and process economics for the production of 2-mercaptobenzothiazole (MBT), a rubber-processing chemical, made from aniline, carbon disulfide, and sulfur. The estimated economics for the manufacture of diphenylamine by the liquid-phase condensation of aniline have also been updated for this report. A discussion of the industry status is presented in a separate section.
