An emulsion is a mixture of two or more liquids that are normally immiscible (unmixable or unblendable) ... The definition is based on the definition in ref. [2]
Emulsified fuels are a type of emulsion that combines water with a combustible liquid, such as oil or fuel. An emulsion is a specialized form of dispersion that contains both a continuous phase and a dispersed phase. The most commonly utilized emulsified fuel is a water-in-diesel emulsion (also known as hydrodiesel). [1]
In polymer chemistry, emulsion polymerization is a type of radical polymerization that usually starts with an emulsion incorporating water, monomers, and surfactants.The most common type of emulsion polymerization is an oil-in-water emulsion, in which droplets of monomer (the oil) are emulsified (with surfactants) in a continuous phase of water.
Micro-emulsion polymerization: Emulsion polymerization in which the starting system is a micro-emulsion and the final latex comprises colloidal particles of polymer dispersed in an aqueous medium. Note : Diameters of polymer particles formed in the micro-emulsion polymerization usually are between 10 and 50 nm.
Strictly speaking a wax emulsion should be called a wax dispersion since the wax is solid at room temperature. However, because the preparation takes place above the melting point of the wax, the actual process is called emulsification, hence the name wax emulsion. In praxis, wax dispersion is used for solvent based systems.
Lipid emulsion or fat emulsion refers to an emulsion of fat for human intravenous use, to administer nutrients to critically-ill patients that cannot consume food. It is often referred to by the brand name of the most commonly used version, Intralipid , which is an emulsion containing soybean oil , egg phospholipids and glycerin , and is ...
Emulsions are thermodynamically unstable liquid/liquid dispersions that are stabilized. [1] Emulsion dispersion is not about reactor blends for which one polymer is polymerized from its monomer in the presence of the other polymers; emulsion dispersion is a novel method of choice for the preparation of homogeneous blends of thermoplastic and elastomer. [2]
This type of emulsion is thermodynamically unstable, but can be stabilized for a period of time with applications of kinetic energy. [1] Surfactants (as the main emulsifiers ) are used to reduce the interfacial tension between the two phases, and induce macroemulsion stability for a useful amount of time.
