Hauv cov ntsiab lus, hypophosphates (xws li sodium hypophosphite, calcium hypophosphite, thiab lwm yam) muaj ntau yam kev siv nyiaj hauv cov tshuaj. Lawv tuaj yeem siv tsis tau tsuas yog raws li buffers, stabilizers, calcium ntxiv thiab antacids rau kev npaj tshuaj npaj thiab kev siv tshuaj kho mob, tab sis kuj rau kev npaj ntawm lwm hom tshuaj thiab biomedical cov ntaub ntawv. Nrog rau kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis thiab kev txhim kho ntawm kev lag luam tshuaj, kev cia siab rau kev siv cov tshuaj hypophosphites hauv kev lag luam tshuaj yuav ntau dua.
Hypophosphorous acid dawssynthesis:
1) Cov tshuaj tiv thaiv daj phosphorus nrog barium hydroxide
Hypophosphite feem ntau yog npaj los ntawm cov tshuaj tiv thaiv daj phosphorus thiab barium hydroxide, thiab ntxiv sulfuric acid kom tshem tawm barium. Txawm li cas los xij, solubility ntawm barium ntsev yog me me, thiab cov concentration ntawm cov tshuaj hypophosphite npaj tsis siab, thiab nws yuav tsum tau concentrated, recrystallized thiab purified.
2) Electrodialysis
Lub hauv paus ntsiab lus ntawm electrodialysis yog tias tom qab lub tank electrodialysis yog energized nrog ncaj qha tam sim no, cov chav zoo thiab tsis zoo tsim cov kev tshwm sim hauv qab no:
Cov chamber zoo thiab cov chamber tsis zoo yog sib cais los ntawm ib qho anionic membrane thiab cationic membrane. Tom qab siv ncaj qha tam sim no, qhov zoo thiab qhov tsis zoo ions txav mus rau qhov tsis zoo thiab zoo electrodes feem. Lub anionic membrane tsuas tso cai rau qhov tsis zoo ions dhau mus, thiab cov cationic membrane tsuas yog tso cai rau cov ions zoo dhau mus. Nyob rau tib lub sijhawm, qhov zoo electrode electrolyzes dej tso tawm oxygen thiab hydrogen ions, uas ua ke nrog dialyzed hypophosphite los tsim hypophosphoric acid, thiab cov electrode tsis zoo tso tawm hydrogen los tso hydrogen, txoj kev electrodialysis yog yooj yim thiab haum rau loj - teev ntau lawm. Tsis muaj dej khib nyiab thiab cov khoom seem, tab sis qhov purity ntawm cov khoom yuav tsum tau txhim kho ntxiv.
Ib txoj kev siv feem ntau rau kev npaj phosphite thiab hypophosphite anhydrides hauv chav kuaj, nrog cov lus qhia ntxaws raws li hauv qab no:
1. Npaj cov khoom siv sim
Phosphorus block: Txiav siab -purity dawb phosphorus rau hauv me me thiab muab tso rau hauv ib lub tais plooj (porcelain).
Oxygen: High purity oxygen rau siv.
Lub qhov cub kub kub: Lub cub tawg uas tuaj yeem tiv taus qhov kub thiab txias thiab siv los ua kom sov phosphorus blocks.
Acid burette: siv los ntsuas cov acidity ntawm cov khoom.
Salt Lake reagent: siv rau kev sib cais hypophosphate thiab hypophosphate.
Dej: siv los txias cov khoom siv tshuaj tiv thaiv thiab yaj cov khoom.
Porcelain phaj: siv los tuav phosphorus blocks.
Cov hnab looj tes, tsom iav, thiab cov tsho hauv chav kuaj: siv los tiv thaiv tus neeg sim kev nyab xeeb.
2. Kev sim cov kauj ruam
Txiav high -purity dawb phosphorus rau hauv me me thiab muab tso rau hauv ib lub tais plooj (porcelain).
Muab cov tais plooj (porcelain) tso rau hauv qhov cub kub - kub, ua kom kub kom kub, thiab tswj qhov kub ntawm lub sijhawm kom oxidize tag nrho cov phosphorus block. Thaum cov txheej txheem no, phosphorus reacts nrog oxygen los tsim phosphite anhydride los yog hypophosphite anhydride. Cov tshuaj sib npaug rau cov tshuaj tiv thaiv no yog:
4P + 3O2 → 2P2O3. P2O3 hais txog phosphite anhydride.
Txhaj siab -purity oxygen rau hauv qhov kub siab- qhov cub kub thiab txuas ntxiv mus nrog phosphorus los tsim hypophosphorous anhydride. Cov tshuaj sib npaug rau cov tshuaj tiv thaiv no yog:
4P + 5O2 → 2P2O5. P2O5 yog hypophosphorous anhydride.
Tshem tawm cov khoom siv tshuaj tiv thaiv sai sai thiab txias rau hauv dej, thaum khaws cov roj tso tawm thaum lub caij txias. Lub sijhawm no, phosphite anhydride lossis hypophosphite anhydride yuav hnov mob nrog dej los tsim cov kua qaub sib xws. Cov tshuaj sib npaug rau cov tshuaj tiv thaiv no yog:
P2O3+3H2O → 2H3PO3(phosphite) los yog P2O5+3H2O → 2H3PO4(hypophosphite).
Muab cov khoom ua kom txias rau hauv cov kua qaub burette thiab titrate nrog cov txheej txheem kev daws teeb meem ntawm kev paub txog kom tau txais cov kua qaub ntawm cov khoom. Cov tshuaj tiv thaiv tshuaj uas tshwm sim hauv cov kauj ruam no yog cov kua qaub- cov tshuaj tiv thaiv hauv paus titration, qhov twg cov txheej txheem tshuaj nyob rau hauv lub burette undergoes ib tug neutralization cov tshuaj tiv thaiv nrog cov generated acid. Tus nqi ntawm cov kua qaub generated tuaj yeem xam raws li tus nqi titration thiab concentration.
Sib cais siv ntsev pas dej reagents raws li acidity kom tau hypophosphate thiab hypophosphate. Txoj kev sib cais tshwj xeeb yuav txawv nyob ntawm seb hom thiab cov kev xav tau zoo ntawm cov khoom xav tau, tab sis feem ntau nws siv cov solubility lossis ion pauv khoom ntawm cov khoom sib txawv hauv cov tshuaj sib cais.
Tshawb xyuas thiab sau cov txiaj ntsig kev sim. Raws li kev sim cov khoom thiab cov ntaub ntawv, ua cov tshuaj ntsuam xyuas los txiav txim qhov muaj pes tsawg leeg, cov ntsiab lus, thiab cov ntsuas zoo ntawm cov khoom, thiab sau cov txiaj ntsig kev sim.
