Thermophysical properties of eutectic mixtures composed by oleic acid and components of essential oils

Currently, replacing traditional solvents with others whose components are considered safe is one of the most important challenges in the chemical industry. However, this change cannot be achieved without understanding the behavior of fluids under different operating conditions. To achieve this, the...
