Tsarin kira natantalum pentachlorideya ƙunshi matakai masu zuwa:
1. Danyen kayan shiri
Shirya high-tsarkikarfe tantalumda chlorine mai tsafta ko hydrogen chloride (HCl) azaman albarkatun ƙasa. Tsabtace takarfe tantalumyana da tasiri mai mahimmanci akan tsabtar samfurin ƙarshe.
2. Chlorination dauki
Hanyar chlorination kai tsaye:Tantalum karfean yanka shi ko an yi foda, sannan a sanya shi a cikin rafin iskar chlorine don maganin chlorination a kewayon zafin jiki na 170-250. Gas na Chlorine yana amsawa tare da tantalum don samarwatantalum pentachloride. Hakanan za'a iya aiwatar da wannan amsa ta amfani da HCl, amma yana buƙatar aiwatar da shi a mafi girman zafin jiki (kamar 400).
Hanyar chlorination kai tsaye: Hakanan ana iya samun Tantalum pentachloride ta hanyar amsa tantalum pentoxide tare da thionyl chloride (SOCl2) a 240 ° C. Ma'aunin amsawa shine: Ta2O5+5 SOCl2 → 2 TaCl5+5 SO2.
3. Rabuwa da tsarkakewa
