Kaphatikizidwe ndondomeko ya tantalum pentachloride

The kaphatikizidwe ndondomeko yatantalum pentachloridemakamaka zikuphatikizapo njira zotsatirazi:

1, Kukonzekera zakuthupi

Konzani chiyero chapamwambatantalum metalndi high-purity chlorine kapena hydrogen chloride (HCl) monga zopangira. Chiyero chatatalumzitsulozimakhudza kwambiri chiyero cha mankhwala omaliza.

2, chlorine anachita

Njira yothira chlorine mwachindunji: Chitsulo cha Tantalum chimadulidwa kapena kupaka ufa, ndiyeno chimayikidwa mumtsinje wa chlorine wa chlorine pa kutentha kwa 170-250. Mpweya wa klorini umakumana ndi tantalum kupanga tantalum pentachloride. Izi zitha kuchitikanso pogwiritsa ntchito HCl, koma ziyenera kuchitika pa kutentha kwakukulu (monga 400).

Njira yothira chloride yosalunjika: Tantalum pentachloride imathanso kupezeka pochita tantalum pentoxide ndi thionyl chloride (SOCl2) pa 240 ° C. Zomwe equation ndi:

Ta2O5+5 SOCl2 → 2 TaCl5+5 SO2.

3, Kulekana ndi kuyeretsedwa

Kuziziritsa mpweya wopangidwa ndi chlorination reaction kuti upangitse kukhala madzi.

Alekanitse ndi kuyeretsa madzi tantalum pentachloride ku zonyansa. Nthawi zambiri, distillation ndi njira zina zimagwiritsidwa ntchito kulekanitsa zonyansa zosiyanasiyana kutengera kusiyana kwawo kwa mfundo zowira. Izi ndizofunikira pakuwonetsetsa kuti tantalum pentachloride ndi yoyera.

4. Kuyanika mankhwala

Yanikani olekanitsidwa ndi kuyeretsedwatantalum pentachloridekuchotsa chinyezi pamwamba ndi zonyansa. Kuyanika chithandizo ndikofunikira kuti pakhale bata komanso chiyero cha tantalum pentachloride.
