bromine in side chain

ethane decolorizes bromine water.

The paper studied the preparation of bromine from basic Magnesium bromide in the production of maltol and ethyl maltol, the synthesis of bromethyl from bromine, sulfur and alcothol.

The brominating agent were used instead of luquid bromine in bromination.

The amount of bromine is about 60～70 percent in bromized polystyrene.

any of the chemical elements fluorine or chlorine or bromine or iodine or astatine.

In this paper, bromized polystyrene flame retardant was synthesized by electrophilic substitution of waste polystrene with bromine using aluminium ehlorid as catalyst.

The products were monobromo-compounds on which the bromine atom occupied the p-position of the activating group.

A process for the preparation of 3,4 dihydroxybenzaldehyde from p hydroxybenaldehyde, bromine and potassium hydroxide was studied, which comprises the steps of bromation and hydrolysis.

Using 2-acetyl benzimidazole and sodium bromide as raw material,2-(dibromine acetyl)-benzimidazole hydrobromate was synthesized with the new bromine that displaced by chlorine gas in light.
