Abstract:

以1, 1′-二羟基-5, 5′-联四唑为原料, 分别与氢氧化锂、氢氧化钠、氢氧化钾反应得到1, 1′-二羟基-5, 5′-联四唑的碱金属盐:1, 1′-二羟基-5, 5′-联四唑二锂盐(Li2DHBT)、1, 1′-二羟基-5, 5′-联四唑二钠盐(Na2DHBT)、1, 1′-二羟基-5, 5′-联四唑二钾盐(K2DHBT), 收率分别为90.6%、91.9%、90.2%。以Li2DHBT为原料, 通过与盐酸羟胺的复分解反应得到1, 1′-二羟基-5, 5′-联四唑二羟胺盐(HATO), 收率为94.1%。利用激光监测技术, 采用动态法测定了20~60 ℃下, HATO、Li2DHBT、Na2DHBT和K2DHBT在水中的溶解度, 利用理想溶液模型和Apelblat方程对实验数据进行了关联。结果表明, 四种盐在水中的溶解度均随温度的升高而增加。理想溶液模型、Apelblat方程的拟合值与实验值的平均相对误差在3.5%以内, 但Apelblat方程对实验数据的关联结果较优。溶解热力学计算结果表明, HATO、Li2DHBT、Na2DHBT、K2DHBT的溶解焓分别为27.991, 27.632, 31.125, 17.991 kJ·mol-1, 溶解熵分别为23.431, 36.807, 41.251, 3.139 J·mol-1·K-1
