Synthesis maitiro e tantalum pentachloride

Iyo synthesis process yetantalum pentachlorideinonyanya kusanganisira matanho anotevera:
1, Kugadzirira kwezvinhu
Gadzirira kuchena kwepamusorotantalum metaluye high-purity chlorine kana hydrogen chloride (HCl) sezvinhu zvakasvibiswa. Kuchena kwetantalum metaline simba rakakosha pakuchena kwechigadzirwa chekupedzisira.
2, Chlornation reaction
Direct chlorination nzira:Tantalum simbiinochekwa kana kupfurwa, yozoiswa murukova rwe chlorine gasi kuitira chlorination reaction patembiricha ye170-250. Chlorine gasi rinosangana ne tantalum kuburitsatantalum pentachloride. Kuita uku kunogonawo kuitwa pachishandiswa HCl, asi inoda kuitwa pane tembiricha yepamusoro (senge 400).
Indirect chlorination method: Tantalum pentachloride inogonawo kuwanikwa nekuita tantalum pentoxide ne thionyl chloride (SOCl2) pa240 ° C. The reaction equation is: Ta2O5+5 SOCl2 → 2 TaCl5+5 SO2.
3, Kuparadzaniswa uye kucheneswa
Kutonhodza gasi rinogadzirwa nechlorination reaction kuti riite kuti riite mvura.
Kuparadzanisa uye kunatsa mvuratantalum pentachloridekubva kutsvina. Kazhinji, distillation nedzimwe nzira dzinoshandiswa kupatsanura tsvina dzakasiyana zvichienderana nekusiyana kwavo kwekubikira. Iyi nhanho ndiyo yakakosha pakuona kuchena kwetantalum pentachloride.
4、 Kuomesa kurapwa
Pukuta zvakaparadzaniswa uye zvakacheneswatantalum pentachloridekubvisa unyoro hwepamusoro uye tsvina. Kuomesa kurapwa kwakakosha kuchengetedza kugadzikana uye kuchena kwetantalum pentachloride.
