Naphthalene is initially sulfonated with sulfuric acid monohydrate under programmed temperature control between 80 and 145℃. Then, 65 % oleum is added gradually at 40℃ and heating is continued for 2.5 h at 145℃. Trisulfonation is complete after the further addition of 65 % oleum and heating for 3 h at 150℃. This complex procedure maximizes the formation of Naphtalene-1,3,6-trisulfonic Acid with a conversion of up to 75 %.
