Antimony bromide

Both antimony tribromide and antimony ttiiodide are prepared by reaction of the elements. Their chemistry is similar to that of SbCl in that they readily hydroly2e, form complex haUde ions, and form a wide variety of adducts with ethers, aldehydes, mercaptans, etc. They are soluble in carbon disulfide, acetone, and chloroform. There has been considerable interest in the compounds antimony bromide sulfide [14794-85-5] antimony iodide sulfide [13868-38-1] ISSb, and antimony iodide selenide [15513-79-8] with respect to their soHd-state properties, ferroelectricity, pyroelectricity, photoconduction, and dielectric polarization.

The presence of zeolite catalysts increases the amount of gaseous hydrocarbons produced during pyrolysis but decreases the amount of pyrolysis oil. Further, significant quantities of coke were formed on the surface of the catalysts in the course of pyrolysis. The catalysts reduced the yield of e.g., as styrene and cumene, in favor of naphthalene. The zeolite catalysts, especially Y-Zeolite, were found to be very effective in removing volatile organo bromine compounds. However, they were less effective in removing antimony bromide from the highly volatile products of pyrolysis (133). 

The zeolite catalysts are very effective in removing volatile organic bromine. However, they are not very effective in removing antimony bromide from the volatile pyrolysis products. Actually, the zeolites cause a dramatic increase of the formation of hydrogen by a factor of 10. In addition, zeolite catalysts were found to reduce the formation of some valuable pyrolysis products, such as styrene and cumene, but other products, such as naphthalene were formed instead (53). 

Reference may also be made to two experimental investigations bearing on this question Isbekow [Z. anorg. Chem. SJ+y 24 (1914)] found that by dissolving the substances mercuric bromide, antimony bromide, bismuth bromide, carbon tetrabromide, etc., in molten aluminium bromide as solvent, solutions were obtained which gave abnormally high molecular weights for the solute and which... 

Antimony compounds are based on antimony, an element that exhibits both metal and nonmetal properties. Many of its compounds are toxic and corrosive, particularly the soluble salts. They include antimony iodide and antimony perchloride. Some antimony compounds decompose in water to produce toxic gases e.g., antimony sulphate decomposes to sulphur dioxide while antimony bromide produces bromine gas. 

A compound is any chemical substance, organic or inorganic, made up of atoms of more than one element. Thus antimony compounds include any of the many chemical combinations of antimony and other elements, including antimony bromide, antimony pentoxide, and antimony sulphate. The most elements thus far identified in a single compound is ten. 

Liquid antimony bromide has relatively low intrinsic electric conductivity which is of the order of 1 x 10 Q cm. As follows from equation [9.2.20], the solutions of such ionic bromides as (CH3)4NBr, NH4Br, KBr, TlBr should show basic properties. This is really so, and three former bases were found to dissociate completely up to concentrations of the order of 10 mol kg. On the contrary, covalent bromides such as AlBrj, certain Lewis acids of antimony Sb(CH3C6H4S03)3 and adducts of SbCl3 of SbX2AlCl4, SbX2FeCl4 compositions are bromide ion acceptors, therefore, they are referred to as acids, since their addition leads to increase of SbX2 concentration in the liquid antimony halides as compared with that in the pure solvent.
