Abstract: The preparation relates to a chemical reaction (I), R+H2SO4 RSO3H+H2O (wherein R is benzene, toluene, ethylbenzene, xylene, crezole, xylenol, chlorophenol, methoxybenzene, dihydroxy benzene, naphthalene, methyl naphthalene, chloronaphthol, naphthol, anthracene, aniline, naphthylamine, aminophenol, toluidine, nitrobenzene, diethylbenzene, dibuthylamine, quinoline, triarylamine, methylnathphalene, docecane and dihexylamine. The preparing method includes reacting an aromatic carbohydrate compound with sulfuric acid to sulfonylate the aromatic carbohydrate compound and produce aromatic sulfonic acid. Specifically, the method includes continuously supplying sulfuric acid through a plurality of feeding inlets, sulfonylating the excessive aromatic carbohydrate compound with insufficient sulforic acid to lower the concentration of the product, aromatic sulfonic acid, condensing the gas emitted from a tower of the reactor to remove water from the phase separator, refluxing the gas to the reaction tower, and purifying the aromatic sulfonic acid in a purification area provided under the reaction tower.
