Some Advances in the Inorganic Chemistry of Bromine

Abstract

Three-dimensional phase correction was successfully tested on two real organic structures: Firstly, on phyllochlorine ester, C33N402H38, where intitial phasing was made on the basis of a n idealized, plane chlorine ring model, the orientation and position of which had been determined by the convolution molecule method (cf. also Fig. 10). Secondly, on the rubidium salt of the "sulfolipid" RbSCg010H17 1391 (initial phasing by the heavy-atom technique with R b and S). In both cases strong, spurious maxima were introduced into the initial Fourier syntheses on account of symmetry elements; in the course of the phase correction these maxima disappeared.

Reversible Release and Fixation of Bromine in Vacancy‐Ordered Bromide Perovskites

“…[11] The procedures for industrial bromine production are relatively mature, in which gaseous chlorine is essentially used to acidify and oxidize the natural brines with following purification and concentration on the crude product. [12][13][14][15][16][17] However, the production of bromine that relies on the "blowout approach" of hypertoxic chlorine is quite obscure. [18] Thus, several alternative methods were explored to synthesize bromine without chlorine, [19,20] including adopting TiO 2 as heterogeneous catalyzer for bromine production, [21][22][23] using CeO 2 /ZrO 2 for hydrogen halides oxidation [17] and electrolysis method.…”
