Addition products containing active bromine, which liberate iodine from potassium iodide solutions in proportions equivalent to their bromine content, are prepared by the action of 1-2 gr. atoms of bromine on 1 mol. of a 2-aryl- #2 - oxazoline or of a 2 - aryl - 4H - 5,6 - dihydro...
It is produced on a large scale by direct reaction of bromine with excess fluorine at temperatures higher than 150 °C, and on a small scale by the fluorination of potassium bromide at 25 °C. It also reacts violently with water and is a very strong fluorinating agent, although chlorine ...

Molecular passivation is a prominent approach for improving the performance and operation stability of halide perovskite solar cells (HPSCs). Herein, we reveal discernible effects of diammonium molecules with either an aryl or alkyl core onto Methylammonium-free perovskites. Piperazine dihydriodide (PZDI...
A method is described for the estimation of bromide-bromine in blood, which depends on liberation of bromine by persulphate in sulphuric acid from a zinc hydroxide filtrate from blood, aspiration of the bromine into iodide, and titration of the liberated iodine with thiosulphate. The method is no...
