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 kwetantalumsimbiine simba rakakosha pakuchena kwechigadzirwa chekupedzisira.

2, Chlornation reaction

Direct chlorination method: Tantalum simbi inochekwa kana kuita upfu, yozoiswa murukova rwe chlorine gasi kuitira chlorination reaction patembiricha ye170-250. Chlorine gasi inopindirana netantalum kugadzira tantalum 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) pa 240 ° 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 kuchenesa mvura tantalum pentachloride kubva kune tsvina. Kazhinji, distillation nedzimwe nzira dzinoshandiswa kupatsanura tsvina dzakasiyana zvichienderana nekusiyana kwavo kwekubikira. Iyi nhanho yakakosha pakuona kuchena kwetantalum pentachloride.

4、 Kuomesa kurapwa

Pukuta zvakaparadzana uye ucheneswetantalum pentachloridekubvisa unyoro hwepamusoro uye tsvina. Kuomesa kurapwa kwakakosha kuchengetedza kugadzikana uye kuchena kwetantalum pentachloride.
