Iyini i-Sodium molybdate CAS 7631-95-0?

I-sodium molybdate, ifomula Na2MoO4. Isisindo se-molecule 205.92. Ikristalu yedayimane elimhlophe. Ikristalu elimhlophe elikhanyayo. Iphoyinti elincibilikayo 687 ℃, ukuminyana kwesihlobo 3.2818. Chaza emanzini. I-Dihydrate ingatholwa nge-crystallization kusuka kusisombululo se-aqueous (isixazululo se-alkaline nge-pH ephakeme kune-8). Lesi sakamuva siyikristalu emhlophe ye-rhombohedral. Ama-MoO42- ions akhona njengama-tetrahedron avamile anobuningi obuhlobene obungu-3.28. Lapho ishiselwa ku-100℃, ama-molecule angu-2 wamanzi ayalahleka ukuze kutholwe into engenamanzi, encibilika kalula emanzini, encibilika ezingxenyeni ezingu-1.7 zamanzi abandayo kanye nezingxenye ezingu-0.9 zamanzi abilayo. Isixazululo esinamanzi esingu-5% ku-25℃ pH 9.0 ~ 10.0, esingancibiliki ku-ethyl acetate. Ngokungeza kancane kancane i-asidi esixazululweni se-sodium molybdate nokunciphisa i-pH yesixazululo, i-molybdate ingenziwa i-polymerized ibe usawoti we-polymolybdate ohlukahlukene, okuhlanganisa i-sodium dimolybdate, i-sodium trimolybdate, i-sodium paramolybdate, i-sodium octamolybdate ne-sodium decamolybdate.

Isicelo

I-sodium molybdate i-sodium molybdate, esetshenziswa njenge-metal corrosion inhibitor, i-ejenti yokususa isikali, umgqugquzeli we-bleaching kanye ne-agent evikela isikhumba nezinwele, esetshenziswa njenge-reagent yokuhlaziya yokunquma i-alkaloid, odayi kanye nemboni yezemithi; I-sodium molybdate ingasetshenziswa ekwenzeni ama-alkaloid, uyinki, umanyolo, umbala obomvu we-molybdenum kanye ne-pigment precipitant esheshayo, i-catalyst, i-molybdenum usawoti, ingasetshenziswa futhi ekwenzeni ama-flame retardants kanye nohlobo olungenayo ukungcola kwamanzi abandayo uhlelo lwe-metal inhibitors, olubuye lusetshenziswe njenge-galvanizing kanye ne-agent yokupholisha amakhemikhali.
