摘要：

Compressions k of formamide (F), N-methylformamide (NMF), N,N-dimethylformamide (DMF), N,N-dimethylacetamide (DMA), and 1-methylpyrrolidin-2-one (MP) were measured at pressures up to 200 MPa and at the temperature 298.15 K. The experimental compressions were fitted to the Tait equation. Isothermal compressibilities κT at the pressure 0.1 MPa for amides were evaluated from the Tait parameters. The κT values for amides at 0.1 MPa decrease in the sequence: DMF ≥ DMA > NMF > MP > F. The sequence of κT values for aliphatic amides is discussed from the viewpoint of liquid structure. © 1991 Academic Press Limited All rights reserved.
