The chemistry term miscible refers to the property of various liquids that allows them to be mixed together. By contrast, substances are said to be immiscible if they cannot be mixed together, e.g., oil and water. Multicolored chemicals are frequent hallmarks of chemistry. ... A liquid will assume the shape of its container. ... Oil is a generic term for organic liquids that are not miscible with water. ... A girl in a swimming pool full of water Water (from the Old English waeter; c. ...


In organic compounds, the length of the carbon chain often determines miscibility relative to members of the homologous series. For example, in the alcohols, ethanol has two carbon atoms and is miscible with water, whereas octanol has eight carbon atoms and is not miscible with water. Octanol's immiscibility leads it to be used as a standard for partition equilibria. This is also the case with lipids, the very long carbon chains of lipids cause them to almost always be immiscible with water. An organic compound is any member of a large class of chemical compounds whose molecules contain carbon, with the exception of carbides, carbonates, carbon oxides and gases containing carbon. ... General Name, Symbol, Number carbon, C, 6 Chemical series nonmetals Group, Period, Block 14, 2, p Appearance black (graphite) colorless (diamond) Atomic mass 12. ... In Chemistry, a homologous series is a series of organic compounds with a similar general formula, possessing similar chemical properties, and showing a gradation in physical properties as a result of increase in molecular size and mass. ... In chemistry, alcohol is any organic compound in which a hydroxyl group (-OH) is bound to a carbon atom, which in turn is bound to other hydrogen and/or carbon atoms. ... Ethyl alcohol, also known as ethanol or grain alcohol, is a flammable, colorless chemical compound, one of the alcohols that is most often found in alcoholic beverages. ... Properties In chemistry and physics, an atom (Greek άτομον meaning indivisible) is the smallest possible particle of a chemical element that retains its chemical properties. ... Octanol is a straight chain fatty alcohol with eight carbon atoms and the formula C8H17OH and its molecular weight is 130. ... Partition equilibrium chromatography is a type of chromatography that is typically used in GC. The stationary phase is a high boiling liquid bonded to solid surface and the mobile phase is a gas. ... Figure 1: Structure of a Lipid. ...


Miscibility can arise for a number of reasons. In the alcohol examples above, the OH group can form hydrogen bonds with water molecules. In aldehydes and ketones the hydrogen bond can form with a lone pair of electrons on the carbonyl oxygen atom. Hydroxide is a polyatomic ion consisting of oxygen and hydrogen: OH− It has a charge of −1. ... Hydrogen bonds between water molecules are diagramatically represented by the black lines. ... In general, a molecule is the smallest particle of a pure chemical substance that still retains its composition and chemical properties. ... An aldehyde is either a functional group consisting of a terminal carbonyl group or a compound containing a terminal carbonyl group. ... Ketone group A ketone is either the functional group characterized by a carbonyl group linked to two other carbon atoms or a chemical compound that contains this functional group. ... In organic chemistry, a carbonyl group is a functional group composed of a carbon atom double-bonded to an oxygen atom. ... General Name, Symbol, Number oxygen, O, 8 Chemical series Nonmetals Group, Period, Block 16, 2, p Appearance colorless Atomic mass 15. ...


In metals, immiscible substances are unable to form alloys. Typically, a mixture will be possible in the molten state, but upon freezing the metals separate into separate phases. This property allows solid precipitates to be formed by rapid freezing of a molten mixture of immiscible metals. One example of immiscibility in metals is copper and cobalt, where rapid freezing to form solid precipitates has been used to create granular GMR materials. The Giant Magnetoresistance Effect (GMR) is a quantum mechanical effect observed in thin film structures composed of alternating ferromagnetic and nonmagnetic metal layers. ...

Miscibility is the ability of two substances to mix together.
When using the term in discussing refrigerants and oils, it refers to the ability of the gas and the oil to remain as one mixture, one homogeneous mixture, as they travel through the system, from the compressor and back to the compressor.
Proper heat transfer and efficient system operation require an oil and a gas that exhibit good miscibility, particularly in the evaporator where temperatures are lower.
Method of forming carbon dioxide mixtures miscible with formation crude oils - Patent 4529037 (1704 words)
This sort of miscible flooding is termed "developed miscibility," or "multiple-contact miscibility," wherein it is thought that the intermediates (C.sub.2 -C.sub.6) of crude oil transfer into the crude oil displacing fluid over a sustained period of exposure, as opposed to "first-contact miscibility," wherein a zone of contiguously miscible fluids will result.
The minimum pressure at which carbon dioxide is miscible with crude oil from a reservoir is determined at the ambient reservoir temperature and is referred to as the minimum miscibility pressure (MMP).
The miscibility of the carbon dioxide with the crude oil is adjusted by addition of hydrocarbons to develop miscibility, carbon dioxide via line 12 is mixed with crude oil introduced via line 14 into a mixing conduit 16.
