Lub solubility nyob rau hauv aromatic hydrocarbons nce raws li tus qauv ntawm benzene < toluene < m-xylene < mesitylene, thiab cov xim ntawm cov tshuaj deepens los ntawm lub teeb daj mus rau txiv kab ntxwv.  

3. Tantalum pentachloride tshuaj muaj zogKev ruaj ntseg: Cov khoom siv tshuaj tsis ruaj khov thiab yuav decompose thiab tsim tantalic acid nyob rau hauv cov huab cua ntub lossis dej. Structure: Tantalum pentachloride yog ib qho dimer nyob rau hauv lub xeev cov khoom, nrog ob tantalum atoms txuas los ntawm ob tug choj chlorine. Hauv lub xeev gaseous, tantalum pentachloride yog ib qho monomer thiab nthuav tawm cov duab peb sab bipyramidal. Reactivity: Tantalum pentachloride yog ib qho Lewis acid uas muaj zog thiab tuaj yeem hnov ​​​​mob nrog Lewis hauv paus los tsim cov adducts. Nws tuaj yeem cuam tshuam nrog ntau yam sib txuas, xws li ethers, phosphorus pentachloride, phosphorus oxychloride, tertiary amines, thiab lwm yam.

4. Tantalum pentachloride Txoj Kev NpajCov tshuaj tiv thaiv ntawm tantalum thiab chlorine: Tantalum pentachloride tuaj yeem npaj tau los ntawm kev ua cov hmoov hlau tantalum nrog cov tshuaj chlorine ntawm 170 ~ 250 ° C. Cov tshuaj tiv thaiv no tuaj yeem ua tau siv HCl ntawm 400 ° C. Cov tshuaj tiv thaiv ntawm tantalum pentoxide thiab thionyl chloride: Ntawm 240 ° C, tantalum pentachloride tuaj yeem tau los ntawm reacting tantalum pentoxide thiab thionyl chloride.

5.Tantalum pentachloride Daim ntawv thovChlorinating tus neeg sawv cev rau cov organic tebchaw: Tantalum pentachloride tuaj yeem siv los ua cov tshuaj chlorinating rau cov organic tebchaw los txhawb cov tshuaj chlorination. Chemical intermediates: Hauv kev lag luam tshuaj, tantalum pentachloride yog siv los ua raw khoom rau kev npaj ntawm ultra-high purity tantalum hlau thiab tshuaj intermediates. Kev npaj ntawm tantalum: Hlau tantalum tuaj yeem npaj tau los ntawm kev txo qis hydrogen ntawm tantalum pentachloride. Txoj kev no suav nrog kev tso cov tantalum los ntawm cov pa roj rau ntawm cov cua sov substrate los tsim cov hlau ntom ntom, lossis txo cov tantalum chloride nrog hydrogen hauv lub txaj ebullating los tsim cov hmoov tantalum spherical. Lwm yam kev siv: Tantalum pentachloride kuj tseem siv rau hauv kev npaj cov iav kho qhov muag, nruab nrab ntawm tantalum carbide, thiab hauv kev lag luam hluav taws xob ua cov khoom siv raw rau kev npaj tantalate thiab rubidium tantalate. Tsis tas li ntawd, nws yog siv nyob rau hauv kev tsim cov dielectrics thiab yog dav siv nyob rau hauv kev npaj ntawm nto polishing deburring thiab anti-corrosion agents.

6.Tantalum pentachloride Cov ntaub ntawv kev nyab xeebKev Nyab Xeeb Kev Nyab Xeeb: Tantalum pentachloride yog corrosive, muaj teeb meem yog tias nqos, thiab tuaj yeem ua rau kub hnyiab heev. Cov ntsiab lus kev nyab xeeb: S26: Tom qab qhov muag pom, yaug tam sim nrog dej kom ntau thiab nrhiav kev kho mob. S36/37/39: Hnav cov khaub ncaws tiv thaiv tsim nyog, hnab looj tes thiab tiv thaiv qhov muag / ntsej muag. S45: Thaum muaj xwm txheej lossis yog tias koj tsis xis nyob, nrhiav kev kho mob tam sim ntawd (tso daim ntawv lo yog ua tau). Cov ntsiab lus txaus ntshai: R22: Ua phem yog tias nqos. R34: Ua rau kub hnyiab. Kev khaws cia thiab kev thauj mus los: Tantalum pentachloride yuav tsum muab khaws cia rau hauv lub thawv kaw kom tsis txhob muaj huab cua ntub lossis dej. Thaum khaws cia thiab thauj mus los, lub tsev khaws khoom yuav tsum tau khaws cia qhov cua, qhov kub thiab txias, thiab qhuav, thiab tsis txhob muab cais tawm ntawm oxidants, cyanide, thiab lwm yam.
