Ilana ti iṣelọpọ ti tantalum pentachloride

Awọn kolaginni ilana titantalum pentachloridenipataki pẹlu awọn igbesẹ wọnyi:

1. Igbaradi ohun elo aise

Mura ga-mimọtantalum irinati chlorine mimọ-giga tabi hydrogen kiloraidi (HCl) bi awọn ohun elo aise. Awọn ti nw titantalumirinni ipa pataki lori mimọ ti ọja ikẹhin.

2, Chlorination lenu

Ọna chlorination Taara: Ti ge irin Tantalum tabi lulú, ati lẹhinna gbe sinu ṣiṣan gaasi chlorine fun iṣesi chlorination ni iwọn otutu ti 170-250. Gaasi Chlorine ṣe atunṣe pẹlu tantalum lati ṣe agbejade tantalum pentachloride. Ihuwasi yii tun le ṣee ṣe ni lilo HCl, ṣugbọn o nilo lati ṣe ni iwọn otutu ti o ga julọ (bii 400).

Ọna chlorination aiṣe-taara: Tantalum pentachloride tun le gba nipa didaṣe tantalum pentoxide pẹlu thionyl kiloraidi (SOCl2) ni 240 ° C. Idogba esi jẹ:

Ta2O5 + 5 SOCl2 → 2 TaCl5 + 5 SO2.

3, Iyapa ati ìwẹnumọ

Tutu gaasi ti a ṣe nipasẹ iṣesi chlorination lati di o sinu omi kan.

Yatọ ati sọ omi tantalum pentachloride di mimọ lati awọn aimọ. Nigbagbogbo, distillation ati awọn ọna miiran ni a lo lati ya sọtọ awọn idoti oriṣiriṣi ti o da lori awọn iyatọ aaye farabale wọn. Igbesẹ yii jẹ bọtini lati ṣe idaniloju mimọ ti tantalum pentachloride.

4, itọju gbigbe

Gbẹ awọn ti o yapa ati mimọtantalum pentachloridelati yọ dada ọrinrin ati impurities. Itọju gbigbe jẹ pataki fun mimu iduroṣinṣin ati mimọ ti tantalum pentachloride.
