Yintoni iSodium molybdate CAS 7631-95-0?

I-sodium molybdate, ifomula Na2MoO4. Ubunzima bemolekyuli 205.92. Ikristale yedayimani emhlophe. Ikristale emhlophe opaque. Indawo yokunyibilikisa i-687℃, ukuxinana kwe-3.2818. Nyibilika emanzini. I-Dihydrate inokufumaneka nge-crystallization kwisisombululo samanzi (isisombululo se-alkaline kunye ne-pH ephezulu kune-8). Le yokugqibela yikristale emhlophe ye-rhombohedral. I-MoO42- ion zikhona njenge-tetrahedron eziqhelekileyo kunye noxinano olunxulumene ne-3.28. Xa ishushu ukuya kwi-100℃, iimolekyuli ezi-2 zamanzi ziyalahleka ukuze zifumane into engenamanzi, zinyibilika ngokulula emanzini, zinyibilika kwi-1.7 iinxalenye zamanzi abandayo kwaye malunga ne-0.9 iinxalenye zamanzi abilayo. I-5% isisombululo samanzi kwi-25℃ pH 9.0 ~ 10.0, i-insoluble kwi-ethyl acetate. Ngokudibanisa ngokuthe ngcembe i-asidi kwisisombululo se-sodium molybdate kunye nokunciphisa i-pH yesisombululo, i-molybdate inokupolymerized kwiintlobo zeetyuwa ze-polymolybdate, kuquka i-sodium dimolybdate, i-sodium trimolybdate, i-sodium paramolybdate, i-sodium octamolybdate kunye ne-sodium decamolybdate.

Isicelo

I-sodium molybdate yi-sodium molybdate, esetyenziswa njenge-metal corrosion inhibitor, i-agent yokususa isikali, umgqugquzeli we-bleaching kunye ne-agent ekhuselayo yesikhumba kunye neenwele, esetyenziswe njenge-reagent yokuhlalutya ukuzimisela kwe-alkaloid, idayi kunye neshishini lamachiza; I-sodium molybdate ingasetyenziselwa ukuveliswa kwe-alkaloids, i-inki, isichumisi, i-pigment ebomvu ye-molybdenum kunye ne-pigment precipitant ekhawulezayo, i-catalyst, ityuwa ye-molybdenum, ingasetyenziselwa ukuveliswa kwee-retardants zedangatye kunye ne-non-pollution uhlobo lwenkqubo yamanzi abandayo yee-inhibitors zetsimbi, ekwasetyenziswa njenge-galvanizing kunye ne-chemical polishing agent.
