摘要 结合LKB-2107微量安瓶热量计和改进的Thermometric微量滴定热量计, 建立一台具有1和3 mL容积的微量滴定热量计, 并用仪器的基线噪声、基线的稳定性、能当量的测量和能量与电压(V)-时间(t)积分面积的线性关系考察了热量计灵敏度和测量精度. 分别用蔗糖的稀释热和十二烷基硫酸钠(SDS)的胶束生成热检验仪器的可靠 性. 测定了SDS和双十二烷基二甲基溴化铵(DDAB)的相互作用能, 并用量热结果讨论其相行为. 从量热实验得到, SDS与DDAB胶束的相互作用焓为?29.53 kJ/mol, SDS与DDAB反应生成盐的反应焓为?125.8 kJ/mol, 混合囊泡生成焓为41.23 kJ/mol, 囊泡再转化为富SDS胶束的焓变为32.10 kJ/mol.
