a process for the production of p-nitrotoluene-2-sulfonic acid, which comprises (a) intimately contacting molten p-nitrotoluene with a mixture of at most 50% by volume of gaseous sulfur trioxide and an inert gas at a temperature in the range of from about 90 to 150* c., the sulfur trioxide being used in about 1 to 15% molar excess over the p-nitrotoluene employed, (b) adding water to the Process of preparing a not discolored p-nitrobenzoic acid by oxidation of p-nitrotoluene with oxygen, which comprises contacting the oxygen with the p-nitrotoluene in an acetic acid reaction medium and in the presence of a cobalt-containing and bromine-containing catalyst at a temperature of 80° to 150° C.

Relative testis weights were unchanged in dosed animals. Potential treatment-related gross lesions were limited to 2 males from the 10000 ppm exposure group which had small testes. The potential energy surfaces (PESs) of three nitrotoluene isomers, such as p -nitrotoluene, m -nitrotoluene, and o -nitrotoluene, have been theoretically built at the CCSD (T)/CBS level.
