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.
This Wikipedia page provides a comprehensive list of boiling and freezing points for various solvents.
The temperature throughout the plot is assumed to be constant. The center trace is a straight line, which is what Raoult's law predicts for an ideal mixture. In general solely mixtures of chemically similar solvents, such as n-hexane with n-heptane, form nearly ideal mixtures that come close to obeying Raoult's law. The top trace illustrates a ...
Hexane (/ ˈ h ɛ k s eɪ n /) or n-hexane is an organic compound, a straight-chain alkane with six carbon atoms and the molecular formula C 6 H 14. [ 7 ] Hexane is a colorless liquid, odorless when pure, and with a boiling point of approximately 69 °C (156 °F).
These results suggest that other components found in petroleum benzine may have additive, synergistic or potentiative effects on the biological effects of n-hexane. [7] Namely, 1000 ppm n-hexane, 3000 ppm n-heptane, and 1000 ppm toluene were reported to have depressing effects on the body weight gain of rats. [8]
Toluene (/ ˈ t ɒ l. j u iː n /), also known as toluol (/ ˈ t ɒ l. j u. ɒ l,-ɔː l,-oʊ l /), is a substituted aromatic hydrocarbon [15] with the chemical formula C 6 H 5 CH 3, often abbreviated as PhCH 3, where Ph stands for the phenyl group. It is a colorless, water-insoluble liquid with the odor associated with paint thinners.
Good solvents are likely to be diethyl ether and hexane. (However, PE only dissolves at temperatures well above 100 °C.) (However, PE only dissolves at temperatures well above 100 °C.) Poly(styrene) has a solubility parameter of 9.1 cal 1/2 cm −3/2 , and thus ethyl acetate is likely to be a good solvent.
Batch heteroazeotropic distillation is an efficient method for the separation of azeotropic and low relative volatility (low α) mixtures. A third component (entrainer, E) is added to the binary A-B mixture, which makes the separation of A and B possible.
