What Is an Emulsion? Definition and Examples

An emulsion is defined as a mixture of two or more normally immiscible (unmixable) liquids. Emulsions are colloids, which are homogeneous mixtures consisting of particles larger than molecules that scatter light, but are small enough that they don't separate. Emulsions consist of two parts: the dispersed phase and the dispersing …

This was undesirable in the process of oil extraction. Thus, the emulsion stability caused widespread attention. In the formation, there were many potential factors that affect emulsion stability, such as the shear rate, the shear time [14, 15], the difference in oil-water properties, and the oil-water ratio [16,17,18].

2.3: LIQUID-LIQUID EXTRACTION

Extraction of neutral compounds. If the desired organic compound is neutral (i.e. is neither acidic nor basic), the extraction sequence usually involves simply extracting with an organic solvent several times. ...
