A Convenient and Economic Way to Produce Anhydrous Hydrogen Bromide

Xian-hong Wang, Manfred Schlösser

Open full text 1 citations

Abstract

All articles of this category Bromide promoted decomposition of tert -butyl bromide in the presence of triphenylphosphine gives, besides isobutene, hydrogen(triphenyl)phosphonium bromide. When heated to approximately 150°C in the presence of xylene, the latter salt liberates hydrogen bromide which may then be trapped in an aprotic solvent such as diethyl ether.
