偏摩尔体积就是一定量溶质溶在一摩尔溶液中所应起的体积变化,它是溶液浓度函数。但要注意偏摩尔体积未必一定为正,也就是说有些物质溶于水后反而会导致体积下降。偏摩尔体积是在等温等压下,往无限大的体系中加入1mol其它组分,体系体积的变化量;或往有限的体系中加入微量的其它组分而引起该体系体积的变化。
偏摩尔体积(partial molar volume):在恒温恒压下,向一足够大的某 一浓度的溶液中加入1mol的物质,引起体系体积的变化量;也可以说是在恒 温恒压下,1mol某组分在...

极限偏摩尔体积 limiting partial molar volumes
One is the study of SC CO_2-tetrahydrofuran (THF) binary mixture system by means of apparent densities of the solvent and partial mole volume of solute. The result suggests that long-range density inhomogeneousity of thesolvent.
论文采用溶剂的表观密度和溶质的偏摩尔体积法研究了超临界二氧化碳-四氢呋喃的二元混合体系,溶质在无限稀释条件下负的偏摩尔体积,表明溶液中形成了溶剂化结构,即溶剂在溶质周围发生聚集,这表明溶剂长程密度的不均匀性。
