Witryna31 mar 2024 · Abstract. There are many products (such as cosmetics, food, etc.) in our daily life made of emulsions, mixtures of water and oil. However, water and oil are essentially immiscible, and both liquids tend to separate into two phases. Interfacial tension is the force acting between two different liquids. Higher interfacial tension … WitrynaThese DESs were immiscible with bitumen or petroleum ether. Coupled with a density difference, a clear phase separation was presented between the bitumen–petroleum ether mixture and DES. The DES functioned as a separating agent, keeping the petroleum ether–bitumen mixture and spent sand apart from each other.
