Synthesis Thiab Decomposition Ntawm Platinum Tetrachloride
Oct 22, 2021
Platinum tetrachloride yog hygroscopic liab-xim av hmoov, yooj yim decomposed ntawm cua sov, yooj yim soluble nyob rau hauv dej thiab acetone, hardly soluble nyob rau hauv ethanol, thiab ua daj PtCl4·5H2O thaum nws absorbs noo noo nyob rau hauv cov huab cua.
Decomposition: Thaum rhuab mus rau 370 ℃ hauv chlorine, nws yuav decomposed rau hauv platinum dichloride thiab chlorine.
Synthesis: Muab chloroplatinic acid tso rau hauv lub nkoj hauv lub khob iav, thiab maj mam nce qhov kub ntawm 60 ° C mus rau 150 ° C kom tag nrho cov dej volatilize. Txuas ntxiv kom sov li 275-300 ° C hauv 2h, khaws cia rau ib nrab ib teev, thiab tom qab ntawd txo qhov kub mus rau 150 ° C. Tom qab cov khoom raug tshem tawm thiab crushed sai sai, nws muab tso rau hauv ib lub nkoj dua thiab rhuab mus rau 275 ° C nyob rau hauv ib tug kwj ntawm chlorine. Cia nws sov li ib nrab teev, thiab muab cov khoom tso rau hauv lub raj mis kaw thaum nws kub.
Kev Siv: Kev siv ncaj qha yog ua kom platinum asbestos siv los ua cov khoom siv hluav taws xob, thiab nws tseem tuaj yeem siv los ua cov tshuaj tiv thaiv kab mob cisplatin, uas muaj cov txiaj ntsig tshwj xeeb rau kev mob qog noj ntshav ntawm zes qe menyuam thiab qog noj ntshav.
Cia: Airtight ntawm chav tsev kub, txias, ventilated thiab qhuav.
