Cov txheej txheem hluavtaws ntawm tantalum pentachhloride

Cov txheej txheem hluavtaws ntawmtantalum pentachhloridemas suav nrog cov kauj ruam hauv qab no:

1, raw khoom npaj

Npaj cov kev coj dawb huvTANANTUM HLAUThiab kev ua kom siab huv chlorine lossis hydrogen chloride (HCl) raws li cov ntaub ntawv raw. Purity ntawmtantalumhlauMuaj kev cuam tshuam tseem ceeb ntawm kev coj dawb huv ntawm cov khoom kawg.

2, chlorination tawm tsam

Cov tshuaj chlorination ncaj qha: TANTALUM hlau yog txhoov lossis hmoov, thiab tom qab ntawd muab tso rau hauv cov tshuaj chlorine roj rau cov ntsuas kub ntawm 170-250. Chlorine roj kev sib haum nrog tantalum los tsim tantalum pentachloride. Qhov tshuaj tiv thaiv no tseem tuaj yeem nqa tawm siv HCL, tab sis nws yuav tsum tau nqa tawm ntawm qhov kub siab dua (xws li 400).

Cov kab mob chlorination tsis tau: Tantalum pentachhloride tseem tuaj yeem tau los ntawm reacting tantoxide nrog thentyl vloride (socl2) ntawm 240 ° C. Qhov kev tawm tsam ntawm 24

TA2O5 + 5 socl2 → 2 tacl5 + 5 so2.

3, sib cais thiab kev ua kom huv

Txias cov roj ua los ntawm cov tshuaj tiv thaiv chlorination kom ua rau nws ua kua.

Cais thiab huv si ua kua tantalum pentachhloride los ntawm impurities. Feem ntau, distillation thiab lwm txoj hauv kev siv los cais cov kev sib txawv ntawm lawv qhov sib txawv npau npau. Kauj ruam no yog qhov tseem ceeb los ua kom muaj kev coj dawb huv ntawm tantalum pentachloride.

4, Kev Kho Kom Qhuav

Qhuav qhov sib cais thiab huvtantalum pentachhlorideTxhawm rau tshem tawm cov dej noo thiab impurities. Kev kho kom qhuav yog qhov tseem ceeb rau kev tswj kom muaj kev ruaj ntseg thiab kev ua yeeb yam ntawm tantalum pentachloride.
