Kev npaj ntawmSodium HexafuorophosphateFeem ntau tau ua tiav los ntawm kev siv tshuaj lom neeg, thiab ib qho ntawm cov txheej txheem kev npaj ib txwm muaj raws li hauv qab no:
Cov tshuaj tiv thaiv kab sib npaug: PCL5 + Nacl +6 hf → Napf6 {}} hcl
Npaj cov kauj ruam:
Ib lub nkoj ua los ntawm cov khoom siv corrosion-resistant cov ntaub ntawv xws li stainless hlau, tooj, tooj, tooj 76.2 hli) thiab ib qho siab ntawm 7 ntiv tes (kwv yees li 177.8mm).
Muab ib nrab ntawm cov nyiaj ntawm sodium chloride rau hauv ib lub taub ntim thiab npog nws nrog lub hau. Txias lub thawv hauv dej khov hauv dej khov nab kuab thiab txuas nws rau ib lub tank anhydrous fluoride.
Qhib lub valve thiab tso kwv yees li 400ml ntawm HF ua kua rau hauv lub thawv. Txij ntawm no, qib ua kua hauv lub thawv hlau stainless yog li ntawm 3/4 nti (kwv yees li xyoo 19.05mm). Ntxig ib rab nyias nyias strip rau hauv cov yeeb nkab nruab nrab, thiab qhov cuam tshuam rau hauv cov kua yuav tig dub, yog li ntxaum ntsuas qhov siab ntawm qib ua kua.
Txhawm rau kom ua tiav cov kev ua tiav ntawm sodium chloride, tshem lub hau thiab do nrog ib rab diav hlau diav nrog tus kov. Maj mam ntxiv txog 15 {{{1} g (txog 0.75mol) ntawm pcl ₅ thiab ntxiv rau kev daws los ntawm ib rab diav (muab tso rau ntawm phab ntsa ntawm lub thawv). Sodium hexafuorophosphathaphaphateghthaphat tam sim ntawd thiab yog do ua kom tiav kom ua tiav cov tshuaj tiv thaiv.
Vim yog cov tshuaj tiv thaiv hnyav, kev ntsuas yuav tsum tau coj los tiv thaiv kev sib cais ntawm cov tshuaj fluoride kua. Tus neeg teb xov tooj yuav tsum hnav hnab looj tes tuab thiab nyiam ua haujlwm tom qab lub hau tiv thaiv. Tom qab tag nrho pcl ₅ tau ntxiv, tshem lub hau thiab muab lub thawv ntim tso rau hauv cov roj da dej kom yaj cov tshuaj fluogen ntau.
Cov roj nitrogen qhuav rau hauv cov thawv thiab ua kom sov kom txog 150 qib kom tshem cov nyiaj fluoride hydrogen fluoride. Tus crude cov khoom tawm yuav luag yog kev saib xyuas theoretical, nrog txoj kev huv ntawm ntau tshaj 95%. Cov impurities feem ntau tau lw hlau ntsev thiab ib qho me me ntawm kev siv tshuaj fluoride.
Dissolve cov khoom lag luam hauv methanol (ntxiv 60g ntawm cov khoom siv rau kev daws qhov kev daws teeb meem, ntsuas nrog phenolphatalein, thiab centrifuge tshem tawm cov impurities insoluble. Cov kev daws teeb meem tau muab tshem tawm los ntawm kev xav thiab crystallized nyob rau hauv siab txo siab kom tau monohydrate. Nws yog tom qab ntawd muab tso rau hauv lub tshuab ziab khaub ncaws uas muaj cov sulfuric acid thiab qhuav kom tau txais cov ntsev anhydous.
