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.
Boiling point: 295 °C (563 °F; 568 K) Solubility in water. 1080 mg/L at 25 °C log P: 2.42 Vapor pressure: ... Diethyl phthalate (DEP) is a phthalate ester. It is a ...
An azeotrope is not a range of concentrations that cannot be distilled, but the point at which the activity coefficients of the distillates are crossing one another. If the azeotrope can be "jumped over", distillation can continue, although because the activity coefficients have crossed, the component which is boiling will change.
[22] [23] [5] Low-molecular-weight phthalates like dimethyl phthalate and diethyl phthalate are used as fixatives for perfumes. [ 24 ] [ 25 ] Dimethyl phthalate has been also used as an insect repellent and is especially useful against ixodid ticks responsible for Lyme disease .

It is miscible in water, alcohol, ether, acetone, and ethylene glycol. [3] DEG is a widely used solvent. [4] It can be a normal ingredient in various consumer products, and it can be a contaminant. DEG has also been misused to sweeten wine and beer, and to viscosify oral and topical pharmaceutical products.
