Zinn(IV)-fluorid | Zinc(II) chloride is a white crystalline solid, strongly hygroscopic and deliquescent. Zinc is required for the enzyme activities necessary for cell division, cell growth, and wound healing as well as the release of vitamin A from the liver. [46] From 1839 Sir William Burnett promoted its use as a disinfectant as well as a wood preservative. [43] The chelate is more stable when the bulky phenyl group is pseudo-equatorial rather than pseudo-axial, i.e., threo rather than erythro. Zinc chloride is a chemical irritant of the eyes, skin, and respiratory system. Zinn(II)-chlorid-Dihydrat CAS 10025-69-1 zur Analyse (max.

Zinc chloride is also a useful starting reagent for the synthesis of many organozinc reagents, such as those used in the palladium catalyzed Negishi coupling with aryl halides or vinyl halides. Rapid cooling of molten ZnCl2 gives a glass, that is, a rigid amorphous solid. Four crystalline forms, so-called polymorphs, of ZnCl2 are known, and in each case the Zn2+ ions are tetrahedrally coordinated to four chloride ligands. … X-ray structure determinations of zinc (II) chloride complexes in strong aqueous solutions have been car-ried out by several investigators, and recently, their results have been summarized by Johansson [1], In view of the results, the highest complex is [ZnCl4]2", which has surely a tetrahedral structure. Following his death however, its use was largely superseded by that of carbolic acid and other proprietary products. Die Kristalle und die Lösung absorbieren an der Luft Sauerstoff unter Bildung von unlöslichem, weißem Oxichlorid, das in Gegenwart von Salzsäure und Zinn wieder reduziert wird.

Further evidence for covalency is provided by the high solu… In similar fashion, ZnCl2 promotes selective NaBH3CN reduction of tertiary, allylic or benzylic halides to the corresponding hydrocarbons. Dilute aqueous zinc chloride was used as a disinfectant under the name "Burnett's Disinfecting Fluid". Zinn(IV)-bromid | [44], Ninhydrin reacts with amino acids and amines to form a colored compound "Ruhemann's purple" (RP). For example, solutions prepared from any of the polymorphs of ZnCl2, as well as other halides (bromide, iodide), and the sulfate can often be used interchangeably for the preparation of other zinc compounds. [8], Es soll in manchen Zahnpasten auch als Zahnschmelzschutz dienen. 1-10 The biggest advantages of ZnCl 2 are its low cost, easy to handle, moderate toxicity and broad spectrum acting as a catalyst.
