| titleOfInvention | A kind of method that no catalyst oxygen oxidation ortho-methylnitrobenzene prepares o-nitrobenzoic acid |
| abstract | A kind of method that no catalyst oxygen oxidation ortho-methylnitrobenzene prepares o-nitrobenzoic acid is related to the preparation method of o-nitrobenzoic acid.Under conditions of any catalyst is not added with, using ortho-methylnitrobenzene as raw material, oxygen is oxidant, sodium hydroxide is alkali, and reaction temperature is 25 85 DEG C, is reacted 5 72 hours in solvent alcohol or its aqueous solution, it is post-treated, it isolates and purifies to obtain the o-nitrobenzoic acid.The method is without catalyst；Raw material and solvent are cheap；And reaction temperature is moderate；Control is readily produced, yield may be up to more than 90%, and prepares and industrialize suitable for a large amount of, have broad application prospects. |
