摘要
Apparent molal volumes and compressibilities are reported for dilute aqueous solutions of cyclic ethers, simple carbohydrates, and related polyhydroxy compounds. The results for carbohydrates are considered in the light of two theoretical descriptions of such systems, i.e., the semiideal solution approach of Stokes and Robinson, and the McMillan-Mayer theory type of approach as employed by Kozak, Knight, and Kauzmann. It is concluded that neither model is satisfactory, and that for these solutions a specific hydration model, described in more detail in another paper, is more satisfactory.
