摘　　要：本文以Ｇ盐为原料，采用低浓度氨水（１４％），在较低温度（１４０℃）和较低压力（１．４ＭＰａ）下，利用加压氨化反应合成了２－萘胺－６，８－二磺酸，产品转化率接近１００％。通过对反应影响因素的研究发现：氨比、反应温度、氨水浓度、ＮａＨＳＯ３用量的提高，反应速率加快。?-Amino-naphthalene-6,8-disulfonic acid has been synthesized by amination of 2-naphthol-6,8-disulfonic acid dipotassium salt at relatively low temperature(140℃)and low pressure(1-4MPa)with a yield about 100%. The factors which can affect the reaction have been investigated. It is found that while the reaction temperature, the amount of ammonia or NaHSO_3, the ratio of ammonia to 2-naphthol-6,8-disulfonic acid dipotassium salt and the concentration of ammonia increase, the reaction rate becomes faster.
