Ethanol (data page) provides detailed information about the chemical properties, physical properties, and safety measures of ethanol.
English: Solid - liquid phase diagram of ethanol water mixtures (melting points, freezing points) Deutsch: Fest - flüssig - Phasendiagramm von Ethanol/Wasser-Gemischen Français : Diagramme de phase solide - liquide de mélanges eau/éthanol (points de fusion, points de solidification)
Ethanol (also called ethyl alcohol, grain alcohol, drinking alcohol, or simply alcohol) is an organic compound with the chemical formula CH 3 CH 2 OH. It is an alcohol, with its formula also written as C 2 H 5 OH, C 2 H 6 O or EtOH, where Et stands for ethyl. Ethanol is a volatile, flammable, colorless liquid with a characteristic wine-like ...
The term alcohol originally referred to the primary alcohol ethanol (ethyl alcohol), which is used as a drug and is the main alcohol present in alcoholic drinks. The suffix -ol appears in the International Union of Pure and Applied Chemistry (IUPAC) chemical name of all substances where the hydroxyl group is the functional group with the ...
Phase diagram (left) and process flow diagram (right) of an apparatus for the azeotropic distillation with "material separation agent". In this case the phase diagram includes a zone where components are not miscible, so following the condensation of the azeotrope, it is possible to separate the liquid components through decantation.
This Wikipedia page provides a comprehensive list of boiling and freezing points for various solvents.
The boiling and recondensation of a mixture of two solvents are changes of chemical state; as such, they are best illustrated with a phase diagram. If the pressure is held constant, the two variable parameters are the temperature and the composition. The adjacent diagram shows a positive azeotrope of hypothetical constituents, X and Y.
Phase equilibrium diagram for 1-butanol–ethanol–water ternary mixture. For this reason, in order to have a comparable productivity and profitability with respect to the petrochemical processes, cost and energy effective solutions for the product purification sections are required to provide a significant product recovery at the desired purity.
