Abstract

The reduction of bromine with sulphur to hydrobromic add in the presence of water can be carried out in one step above 70Β°. An aqueous solution containing about 45% of hydrobromic acid and 8% of sulphuric acid is obtained. The process is not only suitable for the preparation of hydrobromic acid in the laboratory, but has also been adapted to large‐scale industrial production. In this case, the dissipation of the heat of reaction was solved by using ice, instead of water, in a suitable apparatus.

## Abstract The reaction of one g.‐atom sulphur, six g.‐atoms bromine and an excess of water has been studied. The reaction takes place in at least two steps, the first being the formation of sulphur mono‐bromide, the second the reaction of this compound with bromine and water. The reaction results

The reaction between formic acid and bromine in strongly acid aqueous media at 298 K Brz + HCOOH -2 Br-+ 2 H+ + COz was studied by absorption spectrophotometry (A = 447 nm). Reaction rates, expressed as H = -d[Brz]/dt, depend on the concentrations of HCOOH (0.3-2.4M), Br2[(2.7-13.6) X 10-3M], H+ (0.

The kinetics and mechanism of the reaction between nitrous acid and bromine are studied in dilute sulfuric acid medium, using both the stopped-flow method and conventional spectrophotometry. The partial reaction order with respect to Br 2 moderately differs from 1, showing a saturation at a higher c
