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.
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]

One of the main cetane improver additives manufactured today is 2-ethylhexyl nitrate (CAS n°: 27247-96-7) [1] which starts to decompose at 130 °C. 2-ethylhexyl nitrate is the result of the reaction of 2-ethylhexanol and nitric acid.
In azeotropic distillation the volatility of the added component is the same as the mixture, and a new azeotrope is formed with one or more of the components based on differences in polarity. [2] If the material separation agent is selected to form azeotropes with more than one component in the feed then it is referred to as an entrainer.
“You got all these people with this disease who need treatment,” he said. “There’s a medication that could really help us tackle this problem, help us dramatically reduce overdose death, and people are having a hard time accessing it.” The anti-medication approach adopted by the U.S. sets it apart from the rest of the developed world.
The other application of the heteroazeotropic distillation is the separation of a binary system (A-B) forming a homogeneous azeotrope. In this case an entrainer or solvent is added to the mixture in order to form an heteroazeotrope with one or both of the components in order to help the separation of the original A-B mixture.
