Hāʻawi ʻo Facoty i ka maʻemaʻe kiʻekiʻe Niobium chloride NbCl5 CAS 10026-12-7

ʻO ka wehewehe pōkole:

Niobium chloride NbCl5

CAS 10026-12-7

Maʻemaʻe: 99.9%

ʻO ka Niobium(V) chloride, i ʻike ʻia ʻo ka niobium pentachloride, he paʻa kalamele melemele.Hydrolyze ia i ka ea, a ua haumia pinepine nā laʻana me nā mea liʻiliʻi o NbOCl₃.Hoʻohana pinepine ʻia ma ke ʻano he precursor i nā pūhui ʻē aʻe o ka niobium.Hiki ke hoʻomaʻemaʻe ʻia ʻo NbCl₅ e ka sublimation.

ʻOi aku ka maikaʻi a me ka hoʻouna wikiwiki ʻana a me ka lawelawe hoʻoponopono

Hoʻohana ʻia no ka hana ʻana i nā pūhui chloro-aryloxide i hui ʻia, e like me [Nb(OC6H3-2,6-i-Pr2)2Cl3]2, e hana ana i ka pyridine a i ʻole phosphine adducts me kahi geometry ʻeono-coordinate distorted.

Hoʻohana ʻia e like me Lewis acid catalyst i ka synthesis organik.

ʻO Niobium(V) chloride ka mea mua i ka hoʻomākaukau ʻana i ka niobium maʻemaʻe, a me ka ferroniobium.Hoʻohana ʻia ʻo ia ma ke ʻano he mea hoʻoheheʻe Lewis acid i ka synthesis organik i ka hoʻoulu ʻana i nā alkenes i ka hopena carbonyl-ene a me ka hopena Diels-Alder.
