Density, viscosity, interfacial tension, contact angle and diffusion coefficient are important system properties in process design and optimization. These quantities are influenced by process conditions such as pressure and temperature, especially in presence of gases that are dissolved in liquid phases. Experimental determination is carried out using optical, gravimentrical and hydrodynamic methods at pressures of up to 250 MPa. The investigated substances range from aqueous solutions and hydrocarbons to polymers, silicone oils and ionic liquids.
