An emulsion is a mixture of two or more liquids that are normally immiscible ... IUPAC. A fluid system in which liquid droplets are dispersed in a liquid.
Therefore, since micro- means 10 −6 and emulsion implies that droplets of the dispersed phase have diameters close to 10 −3 m, the micro-emulsion denotes a system with the size range of the dispersed phase in the 10 −6 × 10 −3 m = 10 −9 m range. Note 3: The term “micro-emulsion” has come to take on special meaning. Entities of ...
IUPAC definition Emulsion in which the particles of the dispersed phase have diameters from approximately 1 to 100 μm. Note 1 : Macro-emulsions comprise large droplets and thus are "unstable" in the sense that the droplets sediment or float, depending on the densities of the dispersed phase and dispersion medium.
IUPAC definition Mini-emulsion : emulsion in which the particles of the dispersed phase have diameters in the range from approximately 50 nm to 1 μm. Note 1 : Mini-emulsions are usually stabilized against diffusion degradation (Ostwald ripening (ref. [ 6 ] )) by a compound insoluble in the continuous phase .
The International Union of Pure and Applied Chemistry (IUPAC / ˈ aɪ juː p æ k, ˈ juː-/) is an international federation of National Adhering Organizations working for the advancement of the chemical sciences, especially by developing nomenclature and terminology.
Chemical nomenclature however (with IUPAC nomenclature as the best example) is necessarily more restrictive: Its purpose is to standardize communication and practice so that, when a chemical term is used it has a fixed meaning relating to chemical structure, thereby giving insights into chemical properties and derived molecular functions. These ...
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.
IUPAC nomenclature is used for the naming of chemical compounds, based on their chemical composition and their structure. [1] For example, one can deduce that 1-chloropropane has a Chlorine atom on the first carbon in the 3-carbon propane chain.
