2-Ethylhexanol exhibits low toxicity in animal models, with LD50 ranging from 2-3 g/kg (rat). [3] 2-Ethylhexanol has been identified as a cause of indoor air quality related health problems, such as respiratory system irritation, as a volatile organic compound. 2-Ethylhexanol is emitted to air from a PVC flooring installed on concrete that had not been dried properly.
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.
Another method, pressure-swing distillation, relies on the fact that an azeotrope is pressure dependent. 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 ...
2-Ethylhexanal is the organic compound with the formula CH 3 CH 2 CH 2 CH 2 CH(C 2 H 5)CHO. A colorless liquid, it is produced on a large scale industrially as a precursor to 2-ethylhexanoic acid and 2-ethylhexanol, both used as precursors to plasticizers. It was studied in the detergent industry since the 1930s. [2]
The gas is a mixture of half nitrous oxide (N 2 O) and half oxygen (O 2). [ 1 ] [ 23 ] The ability to combine N 2 O and oxygen at high pressure while remaining in the gaseous form is caused by the Poynting effect (after John Henry Poynting , an English physicist). [ 1 ]
During induction of general anesthesia, when a large volume of a gas (e.g. nitrous oxide) is taken up from alveoli into pulmonary capillary blood, the concentration of gases remaining in the alveoli is increased. This results in effects known as the second gas effect [1] and the "concentration effect". These effects occur because of the ...
Positive azeotropes are also called minimum boiling mixtures or pressure maximum azeotropes. A well-known example of a positive azeotrope is an ethanol –water mixture (obtained by fermentation of sugars) consisting of 95.63% ethanol and 4.37% water (by mass), which boils at 78.2 °C. [ 10 ]
The effect is named after Bernard Raymond Fink (1914–2000), whose 1955 paper first explained it. [1] [4] When a patient is recovering from N 2 O anaesthesia, large quantities of this gas cross from the blood into the alveoli (down its concentration gradient) and so for a short period of time, the O 2 and CO 2 in the
