Formate ea sodium

Formate ea sodiumke phofo e tšoeu e monyang kapa kristale, e nang le monko o fokolang oa asiti ea formic. E qhibiliha ka metsing le glycerin, e qhibiliha hanyane ka har'a ethanol, ha e qhibilihe ka har'a ether. Chefo. E ka sebelisoa ho hlahisa acid e formic, oxalic acid, formamide le phofo ea inshorense, indasteri ea letlalo, chrome tannery camouflage acid, e sebelisoang ho li-catalysts.

Thepa:Sodium formate ke phofo e tšoeu ea kristale, hygroscopic hanyenyane, monko o monate oa acidic, o qhibiliha ka metsing, o qhibiliha hanyenyane ka ethanol, o sa qhibilihe ka ether, matla a khoheli a itseng 1.919, ntlha e qhibilihisang 253 ℃, delix moeeng, botsitso ba lik'hemik'hale.

Lisebelisoa tsa mantlha:

E sebelisoa indastering ea letlalo, ts'ebeliso ea mantlha ke e latelang:

(1) Haholo-holo e sebelisoa ha ho etsoa formic acid, oxalic acid le phofo ea inshorense, empa hape e sebelisoa ho hlahisa dimethylformamide, joalo-joalo E boetse e sebelisoa meriana, khatiso le indasteri ea ho daea. ;

(2) li-reagents, li-disinfectants le mordant bakeng sa qeto ea phosphorus le arsenic;

(3) E sebelisoa e le sebapi.bakeng sa ho roala ha alkyd resin, plasticizer, matla;

(4) E sebelisoa e le liqhomane, lisebelisoa tse hananang le asiti, oli e tlotsang ea sefofane, li-additives tse khomarelang.

Formate ea sodium leCalcium formate:

Formate ea sodium le formate ea calcium ke matsoai a mabeli a tloaelehileng a tšepe a formate. Formate ea sodium e boetse e tsejoa e le sodium formate. Ho na le mefuta e 'meli ea limolek'hule ea metsoako ea sodium formate ka tlhaho:

① Anhydrous sodium formate ke phofo e tšoeu ea kristale, e nang le hygroscopic, e chefo. Tekanyo e lekanyelitsoeng ke 1.92(20 ℃) ​​mme ntlha e qhibilihang ke 253 ℃. E qhibiliha ka metsing, e qhibiliha hanyane ka har'a ethanol, 'me ha e qhibilihe ka har'a ether.

② Sodium dihydrate ke kristale e se nang mebala. Hanyenyane formic acid monko, chefo. E qhibiliha ka metsing le glycerin, e qhibiliha hanyenyane ka ethanol. Ha mocheso o le holimo, e robeha ho ba hydrogen le sodium oxalate, 'me qetellong e be sodium carbonate. E hlahisoa ke ho sebelisana ha formic acid le sodium hydroxide.

Lisebelisoa tse ka sehloohong tsa sodium formate ke tse latelang:

Formate ea sodium e ka sebelisoa e le reagent ea tlhahlobo ea lik'hemik'hale, e sebelisetsoang ho etsa qeto ea lihlahisoa tsa arsenic le phosphorus, empa hape e sebelisoa e le sebolaea likokoana-hloko, mordant, joalo-joalo indastering, formate ea phofshoana ea sodium e sebelisoa ho nka sebaka sa acid e entsoeng ho ntlafatsa ts'ebetso ea tsamaiso ea FGD ea limestone.

Mokhoa oa ho lokisa sodium formate:Sodium bicarbonate e sebelisoa ka laboratoring ho itšoara ka acid ea formic ho boloka tharollo ea alkaline, ho tlosa Fe3+, filthara, ho eketsa asiti ea formic ka har'a filtrate, ho etsa hore tharollo e be acidic e fokolang, e fetohe mouoane le ho khanya ho fumana formate e tala ea sodium.

Calcium formate ke phofo e tšoeu ea kristale e phallang mahala e nang le anti-mold, anti-corrosion le antibacterial effects. Ke motsoako oa phepo ea asiti ea organic. Likahare tsa 99%, 69% formic acid, 31% calcium, metsi a tlase. Sehlahisoa sena se na le ntlha e phahameng ea ho qhibiliha 'me ha ho bonolo ho senngoa ka thepa ea granular. Kenya 0.9% ~ 1.5% ho fepa. Sehlahisoa sena se arola acid ea formic ka mpeng, e fokotsa pH ea mpa, e boloka acidity ea tšilo ea lijo, 'me e thibela kholo ea libaktheria tsa pathogenic, kahoo e laola le ho thibela ho hlaha ha letšollo le amanang le tšoaetso ea baktheria. Trace formic acid e ka kenya tšebetsong ketso ea pepsinogen mme ea ntlafatsa ho monya ha metsoako e sebetsang lijong. Chelate e nang le liminerale phepelong ho khothaletsa tšilo ea lijo le ho monya ha liminerale; E ka boela ea sebelisoa e le tlatsetso ea calcium. E ka thibela letšollo le ho ntlafatsa sekhahla sa ho phela ha malinyane. Khothaletsa phetolo ea lijo le ho eketsa phaello ea letsatsi le letsatsi.

Ho paka, ho boloka le ho tsamaisa:Liphutheloana tse tiisitsoeng ka meqomong ea tšepe e koahetsoeng ka filimi ea polasetiki, e bolokiloeng sebakeng se pholileng, se omeletseng, se nang le moea o motlakase, qoba letsatsi le tobileng, hole le mehloli ea mocheso, acid, metsi, moea o mongobo.

Qetellong, sodium formate ke motsoako oa bohlokoa o bapalang karolo ea bohlokoa liindastering tse fapaneng. E sebelisoa ha ho etsoa lik'hemik'hale tse ngata tse hlokahalang, ho akarelletsa le formic acid, oxalic acid, formamide le dimethylformamide, 'me e boetse e sebelisoa indastering ea letlalo. Botsoalle ba eona ba tikoloho, ho tšoarella, le ho feto-fetoha ha maemo ho etsa hore e be khetho e nepahetseng lits'ebetsong tse 'maloa. Ka hona, ke motsoako o lokelang ho hlahlojoa ke liindasteri tse ka ruang molemo haholo ho thepa ea eona.
