Ferrous sulfate heptahydrate CAS: 13463-43-9

piav qhia luv luv:

Ferrous Sulphate Hephydrate: Cov kua qaub ntsuab, FeSO4.7H20, tau paub txij li xyoo pua kaum peb; nws crystallizes los ntawm cov tshuaj ntawm hlau lossis hlau hauv cov kua qaub sulfuric acid dilute. Lub heptahydrate tsim cov siv lead ua monoclinic ntsuab ntawm qhov ceev 1·88, yaj tau zoo heev hauv dej (296 g litre-1 FeS04 ntawm 25 ° C). Los ntawm kev ua kom cov kua dej nrog ethanol, cua sov lub heptahydrate mus rau 140 ° hauv vacuo lossis los ntawm kev crystallizing nws los ntawm 50% sulfuric acid, cov monohydrate dawb tau txais. Qhov no tuaj yeem ua kom qhuav ntxiv rau cov dawb, amorphous FeSO4 los ntawm cua sov mus rau 300 ° hauv hydrogen tam sim no. Ntawm qhov kub liab lub sulphate decomposes: 2FeS04 -> Fe203 + S02 + S03 Ib qho tetrahydrate, FeS04.4H20, crystallizes los ntawm cov kua dej saum toj no 56 °.

Cov ntawv thov ntawm Ferrous Sulphate Hephydrate

1. Cov tshuaj ntxiv rau kev noj haus (ua kom hlau zoo); ua kom cov txiv hmab txiv ntoo thiab zaub muaj xim; piv txwv li, cov khoom ntsev siv ua ke nrog alum qhuav hauv eggplant tuaj yeem tsim cov ntsev sib xyaw ruaj khov nrog nws cov xim kom tiv thaiv kev hloov pauv los ntawm cov organic acids. Txawm li cas los xij, nws yuav tsum tau sau tseg, piv txwv li, nws yuav hloov mus ua cov kua dub thaum muaj hlau ntau dhau. Thaum cov alum ntau dhau, cov nqaij ntawm cov nqaij eggplant pickled yuav khov dhau. Piv txwv li kev tsim: eggplant ntev 300 kg; ntsev noj tau 40kg; ferrous sulfate 100g; alum qhuav 500g. Nws tseem tuaj yeem siv ua tus neeg sawv cev tsim xim ntawm cov taum dub, taum pauv qab zib thiab kelp. Cov khoom noj uas muaj tannins, txhawm rau kom tsis txhob ua rau dub, yuav tsum tsis txhob siv. Nws kuj tseem tuaj yeem siv rau kev tua kab mob, tshem tawm ntxhiab thiab tua kab mob tsis muaj zog heev.
2. Cov noob taum uas muaj cov xim cryptochromic tsis muaj xim thaum lub xeev txo qis tab sis raug oxidized ua dub thaum oxidation hauv alkaline mob. Kev siv cov khoom txo qis ntawm ferrous sulfate tuaj yeem ua tiav lub hom phiaj ntawm kev tiv thaiv xim nrog rau kev siv nyiaj ntawm 0.02% txog 0.03%.
3. Yog siv rau kev tsim cov ntsev hlau, cov xim hlau oxide, mordant, tus neeg sawv cev ntxuav, cov tshuaj preservatives, cov tshuaj tua kab mob thiab tshuaj rau cov tshuaj tiv thaiv kab mob anemia.
4. Ferrous sulfate (FeSO4) kuj tseem hu ua hlau sulfate lossis hlau vitriol. Nws yog siv rau hauv kev tsim ntau yam tshuaj lom neeg, xws li sulfur dioxide thiab sulfuric acid.
5. Ferrous Sulfate yog ib yam khoom noj khoom haus thiab khoom noj khoom haus ntxiv uas yog qhov chaw ntawm hlau. Nws yog ib qho hmoov dawb mus rau greyish tsis muaj ntxhiab. Ferrous sulfate heptahydrate muaj kwv yees li 20% hlau, thaum Ferrous sulfate qhuav muaj kwv yees li 32% hlau. Nws yaj qeeb qeeb hauv dej thiab muaj bioavailability siab. Nws tuaj yeem ua rau muaj kev hloov pauv thiab rancidity. Nws yog siv rau kev txhawb nqa ntawm cov khoom sib tov ci. Hauv daim ntawv encapsulated nws tsis cuam tshuam nrog lipids hauv cov hmoov nplej. Nws yog siv rau hauv cov khoom noj menyuam yaus, cov nplej zom, thiab cov khoom pasta.
6. Cov Khoom Noj Ntxiv Hlau.
