Abstract
Organic synthesis intermediates m-aminobenzenesulfonic acid synthesis method, comprises the following steps: adding 2 mol 3-methylaniline, 3-4 mol sulfuric acid solution and 10-13g alumina powder in the reaction vessel, raising the temperature of the solution to 40-45 °C, controlling the stirring speed at 90-110 rpm, stirring for 90-110 min , raising the solution temperature to 70-80 °C, refluxing for30-40min, washed with potassium bromide solution, washed with cyclohexane solution, washed with ketone solution, dehydrated with dehydrating agent, recrystallized in isopropanol solution, finally get the crystal m-aminobenzenesulfonic acid.
