Usage

General Description

2-Methoxybutane, also known as ethyl isopropyl ether or 1-isopropoxypropane, is a flammable organic compound with the molecular formula C5H12O. This ether is primarily used as a solvent due to its chemical stability. It is a colorless, liquid ether that has a distinct smell. It has a boiling point of 63 degrees Celsius and a flash point of -24 degrees Celsius. It is insoluble in water but can dissolve in other organic solvents. 2-Methoxybutane is produced via the reaction between 2-propanol and ethyl bromide. Prolonged exposure or inhalation of this chemical can cause irritation to the skin, eyes, and respiratory tract, making careful handling essential when using it.

Alcohol Dehydration: Mechanism of Ether Formation Using an Alumina Catalyst

Ether formation during the dehydration of secondary alcohols, namely, 2-butanol, 3-pentanol, and 1-cyclopentylethanol, was investigated.Using the proper reaction conditions, the yield of di-2-butyl ether during the dehydration of 2-butanol on alumina can be as high as 40percent.That ether is formed by adding an alcohol to the alkene is ruled out by the results from deuterium tracer studies.Results from experiments using S(+)-2-butanol suggest that the formation of di-2-butyl ether occurs by a SN2-type mechanism.

Onium Ylide Chemistry. 3. Evidence for Competing Oxonium Ylide Formation with C-H Insertion in Meerwein's Reaction of Methylene and Methylene-d2 with Dialkyl Ethers

Meerwein's reaction of singlet methylene, produced by photolysis of diazomethane, with dialkyl ethers has been reinvestigated on the basis of reactions using CD2N2.In competition with methylene insertion into the various C-H bonds, about 10percent of methyl alkyl ether and small amounts of dimethyl ether formation are also observed.This indicates evidence for competing attack of methylene on oxygen leading to the corresponding intermediate methylenedialkyloxonium ylides which are immediately protonated by methyl alkohol (or water)impurity present in the reaction medium togive the corresponding methyldialkyloxonium ions.Dealkylative cleavage of the latter gives the observed methyl alkyl ethers.By the use of deuterium-labeled diazomethane CD2N2 it has been shown that ethylene and propylene formed under the reaction conditions are coming predominantly from diazomethane itself and not via intramolecular β-elimination of the oxonium ylides.
