用途高純度金属化合物。
使用Nickel(II) chloride hexahydrate has been used:in the preparation of nickel platting solution for galvanostatically coating nickel inside the reduced carbon layer during the synthesis of multiwall carbon nanotube micromotorsin screening of metals for inflammatory effect on vascular endothelial cellsas an additive in artificial cerebrospinal fluid (ACSF) to analyse excitatory post synaptic currents (EPSPs) in the hippocampus slices
一般的な説明Nickel(II) chloride hexahydrate is a nickel salt that can be used as a catalyst. It is cost effective and can be used in a variety of industrial processes. It can also be used in cross-coupling reactions.
調製方法
純化方法It crystallises from dilute HCl to form the green hexahydrate. At 70o this dehydrates to the tetrahydrate, and at higher temperatures it forms the anhydrous salt. It sublimes in yellow hexagonal scales in a stream of HCl. Store it in a desiccator as it is deliquescent. [Hart & Partington J Chem Soc 104 1943.]
