Sodium acetate

Ib tug tshuaj uas tshuaj mis yog - CH3COONa - yog sodium ntsev ntawm acetic acid los yog sodium acetate. Nws kuj sau npe nyob rau hauv lub thoob ntiaj teb register ntawm noj tshuaj pab nyob rau hauv lub qhov tooj E-262.

Cov tshuaj yeeb dej caw yog ib tug siv lead ua, ntxoov ntawm cov xim uas tej zaum yuav nyob rau hauv ntau ntawm daj ntseg daj rau sib sib zog nqus xim av. Lub domestic ib puag ncig yog tseem siv los ntawm lub npe ntawm sodium acetate. Cov tshuaj yeeb dej caw sodium acetate - nonflammable, kev ruaj ntseg kev faib hauj lwm rau lub plaub qib. Sodium acetate tawg-pov thawj thiab muaj tsawg toxicity, nws yog nyob rau hauv ntau txoj kev uas vim nws dav siv nyob rau hauv lub muaj ntau lawm thiab lub neej txhua hnub.

Nws yog tau los ntawm cov tshuaj tiv thaiv nrog NaOH los yog Na2CO3 acetic acid los yog esters ntawm no acid. Ua yeeb tshuaj, feem ntau yog ib cov khoom. Nyob rau hauv lub muaj zus tau tej cov loj feem ntawm ntsev nyob rau hauv lub anhydrous lub xeev yog teem rau feem ntau tsis tsawg tshaj li 50%. Tswv yim daim ntawv thov yuav tsum tau tshuaj yuav raug tej yam tej yam kev mob, e.g., kub txwv raws li (ambient kub yuav tsum tsis pub tshaj 5 degrees).

Cov tshuaj lag luam feem ntau yog tsim nyog los neutralize corrosive tshuaj thiab cov tebchaw. Ib tug xws li cov ntaub ntawv uas yog sulfuric acid. Yuav kom neutralize nws, thiab sodium acetate yog siv, concentrated sulfuric acid yog neutralized tsim oksosoli Na2SO4, tej hlauv thaum lub sij hawm neutralization cov tshuaj tiv thaiv tsim ib tug dawb precipitate. Cov tshua hem thawj tiv thaiv raug kuab lom thiab kub yus nyob rau hauv cov ntaub ntawv ntawm to ntawm sulfuric acid.

Raws li twb tau sau tseg, cov tshuaj yeeb dej caw yog dav siv nyob rau hauv ntau yam teb. Nyob rau hauv lub textile kev lag luam siv nws cia li raws li nyob rau hauv lub peev xwm mus neutralize remnants ntawm lub pov tseg sulfuric acid nyob rau hauv cov nroj tsuag emissions, raws li zoo raws li nyob rau hauv qhov siv thiab ua ntau yam dyes aniline pab pawg neeg (siv raws li ib tug photoresist - photosensitive txheej). Nyob rau hauv zus tau tej cov hluavtaws roj hmab daim ntawv thov ntawm sodium acetate raws li nws muaj peev xwm mus qeeb thaum lub sij hawm vulcanization.

Nyob rau hauv cov zaub mov kev lag luam, sodium acetate yog siv raws li ib tug preservative.

Kev sodium acetate yog dav siv raws li additives rau ntau yam antimoroznoy ua concretes yog siv nyob rau hauv kev tsim kho ntawm lub tsev pob zeb ua lug, thiab ua lwm yam tsev ua hauj lwm uas txuam nrog rau kev sib khi thiab ntxiv dag zog rau cov lug ntawm tsawg kub. Daim ntawv thov no yog vim lub peev xwm mus tiv thaiv kom txhob khov ntawm cov tshuaj yeeb dej caw ntawm qhob hmoov sib tov nyob rau hauv yuav luag tag nrho cov mus ntawm lub tsev technology - kev thauj mus los, vaj tse preservation, masonry thiab lwm tus neeg. Nyob rau hauv kev, sodium acetate txhawb settable mixtures ntawm tsawg kub, tsis muaj txos lawv zoo thiab tsis muaj complicating cov txheej txheem rau lawv npaj. Nws siv heev tsis muaj zog txog corrosive siv assembling txheej txheem thiab txhawb kom lub dag lub zog ntawm qhob.

Faib los ntawm kev siv ntawm sodium acetate nyob rau hauv lub khw muag tshuaj raws li ib tug tivthaiv rau qhov siv thiab ua diuretics, raws li zoo raws li alkalinization ntawm tus kab mob nyob rau hauv hyponatremia thiab metabolic acidosis.

Tau cov khoom no yuav ua tau, thiab nyob rau hauv lub tsev. Yuav ua li cas yuav ua rau sodium acetate nyob hauv tsev? Nws yog ib qho yooj yim. Siv 1 kg ntawm zoo tib yam dej qab zib thiab 1 liter ntawm vinegar. Ces, heev maj mam, sib tov rau lawv nyob rau hauv ib khob ntim, cov txheej txheem yuav mus ntxiv raws li ntev kom txog thaum lub hissing nres. Koj muaj rau hauv qab ntawm cov hlab yuav ua tau ib tug monolithic hydrated sodium acetate. Ces nws yuav tsum tau rhuab mus kiag li yaj thiab tshem tawm cov precipitate los ntawm pom. Tau nyob rau hauv cov ntshiab daim ntawv molten iav yuav tsum tau txias rau chav tsev kub ua ntej ntim. Koj tau txais cov tshuaj yeeb dej caw nyob rau hauv cov kua daim ntawv, muab nws ib tug khoom daim ntawv no yog heev yooj yim - nws yog tsim nyog nyob rau hauv cov kua siv lead ua mus ntxiv cia li ib tug me ntsis ntawm tib sodium acetate. Yog li, ib tug yuav ua ntau yam Overstore tshuaj, nyob ntawm seb uas nws sau ua ib pawg xeev yog tsim nyog.
