Ukrainian Journal of Physics| Zusammenfassung: | The viscoelastic properties of liquid aliphatic alcohols (propanol-1, pentanol-1, and heptanol-1) have been compared with the properties of their fluoro-substituted analogs. Experimental data on the density, kinematic viscosity, and sound velocity of the liquids, as well as their critical and van der Waals parameters simulated by artificial neural networks, are used. The comparison of the properties of indicated alcohols with those of water, where there is a continuous network of hydrogen bonds, and hydrogen peroxide, where there are hydrogen bonds, but not their network, shows that the change in the physical properties after the fluoro-substitution is associated with the density of hydrogen bonds in the liquid. |
