At atmospheric pressure, mixtures of ethanol and water form an azeotrope at about 89.4 mol% ethanol (95.6% ethanol by mass, [83] 97% alcohol by volume), with a boiling point of 351.3 K (78.1 °C). [84] At lower pressure, the composition of the ethanol-water azeotrope shifts to more ethanol-rich mixtures. [85]
Molal freezing point constant: ... 424.95: 456.15: 491.15: 515.15 ... Excess volume of the mixture of ethanol and water (volume contraction)
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.
The purity of rectified spirit has a practical limit of 97.2% ABV (95.6% by mass) [2] when produced using conventional distillation processes, as a mixture of ethanol and water becomes a minimum-boiling azeotrope at this concentration. However, rectified spirit is typically distilled in continuous multi-column stills at 96–96.5% ABV and ...
To reduce the eutectic melting point in the solar molten salts, calcium nitrate is used in the following proportion: 42% Ca(NO 3) 2, 43% KNO 3, and 15% NaNO 3. Lidocaine and prilocaine —both are solids at room temperature—form a eutectic that is an oil with a 16 °C (61 °F) melting point that is used in eutectic mixture of local anesthetic ...
This liquid is miscible with water, and at standard atmospheric pressure (101.325 kPa) has a boiling point of 286.5 °C and a freezing point of −7 °C. It is also soluble in ethanol, acetone, acetic acid, glycerine, pyridine, aldehydes; slightly soluble in diethyl ether; and insoluble in oil, fat and most hydrocarbons.
Each model membrane consists of a high concentration of one of the host membranes/phospholipids (95% mol %), low concentrations of two exchanging lipids (2.5 mol% each for a total of 5%), varied mole percentages of cholesterol (0–30 mol %) plus a constant concentration of ethanol (5% v/v). [4]
A study that did not prevent respiratory uptake found that applying 200 mL of hand disinfectant containing 95% w/w ethanol (150 g ethanol total) over the course of 80 minutes in a 3-minutes-on 5-minutes-off pattern resulted in the median BAC among volunteers peaking 30 minutes after the last application at 17.5 mg/L (0.00175%).
