The excess free energies of aqueous solutions containing N-acetyl-L-prolinamide, N-acetyl-N-methyl-L-alaninamide and binary mixtures of these have been determined at 25°C from isopiestic measurements. The corresponding excess enthalpies for the last two systems have been obtained from enthalpy of dilution measurements. The results derived have been considered using the Savage-Wood group additivity
含有 N-乙酰基-L-脯氨酰胺、N-乙酰基-N-甲基-L-丙氨酰胺和它们的二元混合物的水溶液的过量自由能已在 25°C 下通过等压测量确定。后两个系统的相应过量焓是从稀释焓测量中获得的。已使用 Savage-Wood 群可加性原理考虑了得出的结果,结果表明,尽管观察到了可能显着的偏差,但效果非常好。
