Cov lus piav qhia luv luv:

Niobium (v) chloride, tseem hu ua niobium pentachhloride, yog lub ntsej muag daj, yog lub suab ua daj. Nws hydrolyzes nyob rau hauv huab cua, thiab kuaj feem ntau paug nrog me me ntawm Nbocl₃. Nws yog feem ntau siv ua ib tug ua ntej ua ntej rau lwm cov tebchaw ntawm niobium. NBCL₅ tej zaum yuav ua kom huv los ntawm sublimation.

Daim ntawv thov

Niobium chloride NBCL5 CAS 10026-12-7

Siv los ua cov tshuaj sib xyaw chloro-arylloxide cov tebchaw, xws li [NB (OC6H3-2, uas yuav ua rau pyridine lossis phosphine ntxiv nrog ib qho kev sib koom ua ke nrog rau kev sib koom ua ke.

Siv raws li lewis acid catalyst hauv synthes synthesis.

Niobium (v) Chloride yog cov tshuaj ua ntej yog ua ntej hauv kev npaj cov ntshiab zoo nkauj niobium, thiab ferrroniobium. Nws yog siv ua lewis acid catalyst nyob rau hauv acgicic synthesis hauv activating alkenes nyob rau hauv lub carbonyl-ene cov tshuaj tiv thaiv thiab cov lus tiv thaiv diels.
