The isothermal compressibility of three terminal diols, monoethanolamine, and water is measured on a unique setup with direct compression at 298 K in a pressure range of 0.1–300 MPa. The lowest baric dependence is determined for ethylene glycol; the highest, for 1,4-butanediol. The crystallization of this diol at ∼80 MPa is observed for the first time. The obtained data are discussed from the viewpoint of the stability of the hydrogen bond networks in the investigated liquids.
