Abstract Amino G acid has been synthesized by amination of 2 naphthol 6,8 disulfonic acid dipotassium salt and 2 amino naphthalene 3,6,8 trisulfonic acid has been synthesized by sulfonation of Amino G acid with oleum.The factors which can affect the reactions have been investigated.It is shown that while the reaction temperature,the reaction time,the concentration of ammonia,the amount of ammonia or NaHSO 3 increases,the Amino G acid yield increases too.By using 40%��60% oleum at 130�� with the ratio of Amino G acid to oleum between 1��7 5��1��8 5,the 2 amino naphthalene 3,6,8 trisulfonic acid yield is about 90%.
