说明

一般描述

Bromoethane (Ethyl bromide) is an alkyl halide. Microwave spectral investigations of ethyl bromide[1] and its isotopic species[2] have been reported. It has been synthesized either by employing Grignard waste water as a precursor3 or by reacting potassium bromide with concentrated sulfuric acid in ethanol.[3]

应用

Bromoethane may be employed as a promoter during the preparation of 1-butene.4 It has been used to prepare anion-exchange membranes, which can be used for the isolation and purification of plasmid DNA and also for the separation of plasmid DNA and RNA from cell lysates, measured using ultraviolet-visible light spectrophotometer.[4]
