Enthalpies of dilution both of solutions of N-acetylsarcosinamide and of ternary solutions equimolal in N-acetylsarcosinamide and N-acetylglycinamide, N-acetyl-L-alaninamide, N-acetyl-L-valinamide or N-acetyl-L-leucinamide have been determined by a microcalorimetric method. The results were employed to calculate the pairwise enthalpic coefficients for both homotactic (like-like) and heterotactic (like-unlike)
测定了 N-乙酰肌氨酸酰胺溶液和 N-乙酰肌氨酸酰胺和 N-乙酰甘氨酰胺、N-乙酰-L-丙氨酰胺、N-乙酰-L-缬氨酰胺或 N-乙酰-L-亮氨酰胺等摩尔三元溶液的稀释焓通过微量热法。结果用于计算同向(相似)和异同(相似-不同)溶质相互作用的成对焓系数。这些成对相互作用系数已经通过群可加性方法进行了分析,并在应用于此类系统时对其效用进行了一些评论。
