反応手順
Furthermore, there is disclosed in Journal of Chemical Society, 1277 (1923) that m-cresol is sulfonated with a fuming sulfuric acid and then the resulting sulfonated m-cresol is nitrated with a mixed acid (nitric acid plus sulfuric acid), but by this method 3-methyl-2-nitrophenol is obtained as a main product and only a small amount of 5-methyl-2-nitrophenol is obtained as a by-product, the total yield being very poor for the reason as mentioned above.
