Usage

General Description

Propyl tert-butyl ether, also known as PTBE, is an organic compound with the chemical formula C7H16O. It is a colorless liquid with a characteristic odor and is commonly used as a fuel additive to improve gasoline combustion and reduce emissions. PTBE is a highly flammable substance and should be handled with care. It has a low solubility in water and is considered to be relatively non-toxic, with no known significant health hazards associated with its use. However, prolonged exposure to high concentrations of PTBE vapor may cause irritation to the respiratory system and skin. Overall, PTBE plays a valuable role in improving the performance and environmental impact of gasoline, but proper handling and safety precautions should be observed when using this chemical.

On the miscibility of ethers and perfluorocarbons. An experimental and theoretical study

Despite their significant polar character, some organic ethers such as diethyl ether were found to be miscible with perfluorocarbon solvents. Solubilities of various ethers in perfluorocarbons and miscibility temperatures were determined. These properties were found to be greatly dependent on the polarity but also size and shape of the ether molecule. Theoretical calculations of the miscibility temperatures of organic solvents and perfluorocarbons using COSMO-RS method were correlated with experimental data. Considering the difficulties in the accurate description of the macroscopic properties, such as miscibility temperatures, from the first principles, the agreement between experimental and theoretical data is reasonable.

Hydrolysis and Alcoholysis of Esters of o-Nitrobenzenesulfonic Acid

The rate of solvolysis of esters of o-nitrobenzenesulfonic acid with water and C1-C4 alcohols is satisfactorily described by two-parametric Hammett-Taft equation with predominating effect of the electronic factor σ*. The effect of the structure of the hydrocarbon rest in the sulfonic ester group does not fit to this relationship.
