应用
Chromium(II) chloride is used in the condensation of aldehydes with trisubstituted chloroalkenes as well as in the synthesis of a highly active precatalyst for ethylene oligimerization. Further uses of chromium(II) chloride include the conversion of terminal olefins into trans-iodocyclopropanes (in conjunction with iodoform and tetraethyl ethylenediamine) with excellent results; generating bis(indenyl)chromium dimers and other various related products. 备注

产品说明 应用 在氢作用下与其他金属卤化物气相共还原生成细分的金属互化物，它们可用作具有有效的热电性、磁性和抗氧化性的结构材料或化合物。
Anhydrous chromium chloride is an important precursor for the low temperature synthesis of anhydrous metal sulfides, nitrides, phosphides, etc. It is also an important precursor for the synthesis of chromium containing mixed metal complexes; example lithium chromium chloride (Li2CrCl4), which shows rapid lithium ion conduction.
Anhydrous chromium chloride finds applications as catalysts, chromizing ferrous metals, steel, etc. The vapor-phase co-reductions with other metal halides by hydrogen results in finely divided intermetallics with applications as structural materials or compounds with useful thermoelectric, magnetic, and oxidation-resistance properties.
Chromium chloride powder is air and water sensitive. Beads have lower surface area and pour easily. 包装 5 g in ampule 法律信息 AnhydroBeads is a trademark of sigma-aldrich Co.
