AB  - Ethylene glycol is a well-known fluid that is recognized for its application in heat transfer processes [1]. In order to improve its characteristics and performances, adding other particles in the mixture of ethylene glycol and water, such as nanoparticles has been investigated [2]. A substance widespread available, easily distributed and cost effective is caffeine. Caffeine can be recycled from coffee or tea waste, which makes it profitable and sustainable. Literature data state that caffeine addition to ethylene glycol improves its properties as a heat transfer fluid, primarily due to higher heat capacities, higher system fluidity and lower viscosity [3]. This work investigates different thermodynamic properties of caffeine + ethylene glycol mixtures. Densities have been measured at high pressures from 
(0,1 – 60) MP and at the temperature range (20 - 140) ºC. All measurements were performed using an Anton Paar DMA 5000 HP density meter with a vibrating tube [4]. The obtained results were fitted by the modified Tammann-Tait equation and parameters were used to determine the isothermal compressibility coefficient, the coefficient of isobaric expansion, the internal pressure and the difference of specific heat capacity at constant pressure and constant volume. Experimental values and calculated thermodynamic parameters reported in this work will help in concluding whether the caffeine + ethylene glycol mixtures are good candidates as heat transfer fluids.
