摘　　要：本文采用催化方法合成得到1 氨基2 羟基4 萘磺酸,探讨了硫酸铜、硫酸亚铁催化剂对反应的影响.结果发现,CuSO4比FeSO4催化能力强,催化剂用量增大,产品收率提高.当CuSO4用量为0.2g,反应时间为8h、反应温度为50℃,产品收率为68.4 .<Abstrcat> 1-Amino-2-hydroxy-4-naphthalenesulfonic acid and a dye intermediate, were synthesized in the presence of catalysts CuSO_4 and FeSO_4. The effect of the these catalysts on the reaction system is discussed. The result has shown that the yield is enhenced as increasing the catalyst dosage, the yield reacheing 68.40/0 in the optimal condition, which the reaction is performed for 8 h at 50℃ in the presence of 0.2 g CuSO_4.
