Ferrous sulfate heptahydrate CAS: 13463-43-9

Cov lus piav qhia luv luv:

Ferrous sulphate: ntsuab vitriol, feso4.7H20, tau paub txij li xyoo kaum peb; Nws crystallizes los ntawm cov kev daws teeb meem ntawm cov hlau lossis hlau hauv qab daus hauv durutic acid. Tus kab mob tau raug mob ntsuab monoclini monoclinic ntawm Ntsej Muag 1 · 8,6 g litre hauv dej (296 g litre-1 fes04 ntawm 25 ° C). Los ntawm kev daws teeb meem aqueive nrog ethanol, cua sov tus heptahydrate mus rau 140 ° hauv vacuo lossis los ntawm crystallizing nws los ntawm 50% sulfuric acid, dawb monohydrate yog tau. Qhov no tuaj yeem ua kom qhuav dej ntxiv rau cov dawb, amorphous feso4 los ntawm cua kub txog 300 ° nyob rau hauv ib tug tam sim no ntawm hydrogen. Ntawm daim tawv xim liab lub sulphate decomposes: 2fes04-> FET04.4H20, crystallizes ntawm cov kev daws teeb meem aqueous saum 56 °.

Cov ntawv thov ntawm ferrous sulphate haphyrd

1.Nws pab cov tshuaj pab (hlau txhim kho); Xim cov txiv ntoo thiab zaub; Piv txwv li, cov khoom ntsev siv ua ke nrog cov alum qhuav hauv egglant tuaj yeem tsim cov ntsev uas tsis ruaj khov los ntawm cov organic acids. Txawm li cas los xij, nws yuav tsum tau sau tseg, piv txwv li, nws yuav hloov mus rau hauv cov kua txob dub thaum ntau ntau cov hlau. Thaum tus nqi ntawm Alum yog siab, cov nqaij ntawm cov nqaij pickplant nqaij yuav dhau los ua cov khoom kim heev. Daim Qauv Qauv Piv Txwv: Ntev Ncauj 300 Kg; Cov ntsev ntsev 40kg; ferrous sulfate 100g; qhuav alum 500g. Nws tseem tuaj yeem siv los ua cov xim tsim tus neeg sawv cev ntawm cov taum dub, qab zib hau taum thiab kelp. Cov zaub mov muaj cov tannins, txhawm rau kom zam dhau qhov ua rau muaj kev sib daj, yuav tsum tsis txhob siv. Nws kuj tseem siv tau rau kev tsis muaj menyuam, deodorization thiab qaug zog tsis muaj zog.
2.Lebes muaj cryptochromic xim yog xim tsis muaj xim thaum ua kom oxidized rau hauv oxidation hauv alkaline mob. Noj kom zoo dua ntawm cov khoom siv txo qis ntawm ferrous sulfate tuaj yeem ua tiav lub hom phiaj kev tiv thaiv nrog 0.02% rau 0.03%.
3.Yog siv rau kev tsim cov hlau ntsev, hlau oxide pigments, mordant, tshuaj ntxuav, tshuaj tua kab mob rau kev tiv thaiv tshuaj rau kev tiv thaiv anti-anemia.
4.Lerrous sulfate (Feso4) tseem hu ua hlau sulfate lossis cov hlau vitriol. Nws yog siv rau ntau cov tshuaj lom neeg, xws li cov sulfur dioxide thiab sulfuric acid.
5.Phov sulfate yog cov khoom noj muaj txiaj ntsig thiab kev noj haus ntxiv uas yog qhov ntawm cov hlau. Nws yog cov hmoov dawb paug rau xim txho tsw ntxhiab tsw. Ferrous sulfate hep- tahydrate muaj kwv yees li 20% hlau, thaum ferrous sulfate qhuav muaj li kwv yees li 32% hlau. Nws yaj qeeb hauv dej thiab muaj siab Bioavailability. Nws tuaj yeem ua rau muaj kev tiv thaiv thiab rancidity. Nws yog siv rau fortification ntawm ci mixes. Hauv cov qauv encapsulated nws tsis hnov mob nrog lipids hauv cov hmoov nplej. Nws yog siv rau cov zaub mov mos ab, cereals, thiab cov khoom noj cov nplej zom.
