САЖЕТАК / ABSTRACT:
This work presents experimental findings from a comprehensive study on protic ionic liquid (PIL)–water mixtures, focusing on 2-hydroxypropylammonium formate (HPF). These systems were explored as next-generation, environmentally friendly hydraulic fluids. The study involved extensive physical and chemical characterization, including density, viscosity, thermal conductivity, electrical conductivity, and specific heat capacity. In addition, the fluids were tested under standard conditions for compatibility with filter materials, foaming behavior, and copper corrosion resistance. Rheological measurements and flow curve modeling were used to evaluate shear behavior. The findings confirm that HPF–water mixtures can meet ISO VG viscosity standards and offer high thermal efficiency, stability, and safety, making them strong candidates for sustainable hydraulic applications.
