Synthesis inzira ya tantalum pentachloride

Gukomatanya inzira yatantalum pentachlorideahanini ikubiyemo intambwe zikurikira:

1 preparation Gutegura ibikoresho

Tegura ubuziranengetantalumna chlorine-isukuye cyane cyangwa hydrogen chloride (HCl) nkibikoresho fatizo. Ubuziranenge bwatantalumicyumaifite ingaruka zikomeye kubuziranenge bwibicuruzwa byanyuma.

2 reaction Igisubizo cya Chlorination

Uburyo bwa chlorine butaziguye: Icyuma cya Tantalum cyaciwe cyangwa gifu, hanyuma kigashyirwa mumigezi ya chlorine kugirango hlorine itangwe nubushyuhe bwa 170-250. Gazi ya Chlorine ifata tantalum kugirango itange tantalum pentachloride. Iyi reaction irashobora kandi gukorwa hifashishijwe HCl, ariko igomba gukorwa mubushyuhe bwo hejuru (nka 400).

Uburyo bwa chlorine butaziguye: Tantalum pentachloride irashobora kandi kuboneka mugukora tantalum pentoxide hamwe na thionyl chloride (SOCl2) kuri 240 ° C. Ikigereranyo cya reaction ni:

Ta2O5 + 5 SOCl2 → 2 TaCl5 + 5 SO2.

3 、 Gutandukana no kwezwa

Hisha gaze ikorwa na chlorination reaction kugirango ihuze mumazi.

Tandukanya kandi usukure amazi ya tantalum pentachloride n'umwanda. Mubisanzwe, distillation nubundi buryo bukoreshwa mugutandukanya umwanda utandukanye ukurikije aho batetse. Iyi ntambwe ni urufunguzo rwo kwemeza ubuziranenge bwa tantalum pentachloride.

4 Kuvura

Kuma abatandukanijwe kandi basukuyetantalum pentachloridegukuraho ubushuhe bwo hejuru hamwe numwanda. Kuvura byumye ningirakamaro mugukomeza gutuza no kwera kwa tantalum pentachloride.
