Abstract
The isothermal compressibilities of three amino alcohols are measured on a unique setup for direct compression in the pressure range of 0.1 to 300 MPa at 298 K. The lowest baric dependence of isothermal compressibility is found for 3-amino-1-propanol, while 2-amino-1-butanol is characterized by the highest isothermal compressibility. The crystallization of 4-amino-1-butanol is observed at pressures of 200–250 MPa. The resulting data are discussed from the viewpoint of the stability of spatial hydrogen bond networks in amino alcohols and are compared to the similar dependences of liquid diols.
