This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.
Cyclopentyl methyl ether (CPME), also known as methoxycyclopentane, is a hydrophobic ether solvent. A high boiling point of 106 °C (223 °F) and preferable characteristics such as low formation of peroxides, relative stability under acidic and basic conditions, formation of azeotropes with water coupled with a narrow explosion range render CPME an attractive alternative to other ethereal ...
Azeotrope. Vapour-liquid equilibrium of 2-propanol /water showing positive azeotropic behaviour. An azeotrope (/ əˈziːəˌtroʊp /) [1] or a constant heating point mixture is a mixture of two or more liquids whose proportions cannot be changed by simple distillation. [2] This happens because when an azeotrope is boiled, the vapour has the ...
Xylenes form azeotropes with water and a variety of alcohols. The azeotrope with water consists of 60% xylenes and boils at 94.5 °C. [3] As with many alkylbenzene compounds, xylenes form complexes with various halocarbons. [12] The complexes of different isomers often have dramatically different properties from each other. [13]
In chemical engineering, azeotropic distillation usually refers to the specific technique of adding another component to generate a new, lower-boiling azeotrope that is heterogeneous (e.g. producing two, immiscible liquid phases), such as the example below with the addition of benzene to water and ethanol. This practice of adding an entrainer ...
Most coatings have four basic components. These are the resin, solvent, pigment and additive systems [5] but the resin or binder is the key ingredient. Continuing environmental legislation in many countries along with geopolitics such as oil production are ensuring that chemists are increasingly turning to waterborne technology for paint/coatings and since resins or binders are the most ...
Moisture-cure polyurethanes -- or polyurethane prepolymer -- are isocyanate -terminated prepolymers that are formulated to cure with ambient water. [1] Cured PURs are segmented copolymer polyurethane-ureas [2] exhibiting microphase-separated morphologies. One phase is derived from a typically flexible (subambient glass transition temperature, T ...
Water-based coatings have largely replaced standard petroleum-based paints for the construction industry; however, solvent-based anti-corrosion paints remain among the most used today. Supercritical water (SCW) is obtained at a temperature of 374.2 °C and a pressure of 22.05 MPa. [ 4 ]
