| Abstract: | Effect of various solvents on yields of 4 nitrobenzoic acid synthesized by oxygen oxidation of 4 nitrotoluene was investigated.It was discovered that oxidation of 4 nitrotoluene by using C 6H 6/MeOH( V/V =5/1)as a solvent at 50℃,2 0MPa O 2 pressure could give 4 nitrobenzoic acid in 66.4% yield and in 99.6% purity |
