Crystalline calcium formate bakeng sa ho fifala ha letlalo

Mekhoa ea tlhahiso: 1, neutralization ea formic acid le hydrated lime ho hlahisa calcium formate, e hloekisitsoeng ho fumana khoebo ea k'halsiamo formate.2, ho senyeha ha motsoako oa sodium formate le calcium nitrate ka pel'a catalyst ho fumana calcium formate, co-production ea sodium nitrate.

Mokhoa oa tlhahiso:

1. Mokhoa oa ho se nke lehlakore

Asiti ea formic ha e sebelisoe ka lime e nang le hydrated ho hlahisa calcium formate, 'me formate ea k'halsiamo ea khoebo e fumanoa ka ho hloekisoa.

2. Mokhoa oa ho qhibiliha oa motsoako

Boteng ba catalyst, sodium formate le calcium nitrate li kena karabelong ea ho bola habeli ho fumana calcium formate le ho hlahisa sodium nitrate. Formate ea k'halsiamo ea khoebo e fumanoe ka ho hloekisoa.

3. Mokhoa oa sehlahisoa oa epoxy fatty acid methyl ester

Tlhahiso ea epoxy fatty acid methyl ester e hōla ka potlako, 'me palo e kholo ea sehlahisoa sa formic acid e hlahisoa ts'ebetsong ea tlhahiso. E 'ngoe ea merero ea tšebeliso ea sehlahisoa sena sa formic acid ke ho hlahisa sebopeho sa calcium.

4. Mokhoa oa tsoalo

Ts'ebetsong ea tlhahiso, calcium hydroxide e sebelisoa ho fana ka maemo a motheo a karabelo, 'me formic acid e eketsoa ka karabelo e latelang le ts'ebetso ea calcium hydroxide neutralization ka nako e ts'oanang ho hlahisa calcium formate.

Formic acid ke asiti ea carboxylic e ka ekeletsoang ho olefin.Asiti ea formic ts'ebetsong ea li-acids (tse kang sulfuric acid, hydrofluoric acid), le olefin li arabela ka potlako ho theha liforomo. Leha ho le joalo, karabelo e ka lehlakoreng e ts'oanang le karabelo ea Koch le eona e ka hlaha, ha sehlahisoa e le acid e phahameng ea carboxylic.

Boleng ba para ea octanol/coefficient ea karohano ea metsi: -, moeli o kaholimo oa ho phatloha % (V/V) :, moeli o tlase oa ho phatloha % (V/V) :.

Formic acid ke sesebelisoa se matla sa ho fokotsa, 'me karabelo ea seipone sa silevera e ka etsahala. Acidic ka mafura a mafura a mangata, ho arohana kamehla ke×10-4. E robeha butle-butle ho ba carbon monoxide le metsi a mocheso oa kamore. E futhumetse ho 60-80e nang le sulfuric acid e teteaneng ho bola le ho lokolla carbon monoxide. Ha formic acid e futhumatsoa ka holimo ho 160° C, e bola ho ntša carbon dioxide le hydrogen. Matsoai a tšepe a alkali a formic acid a futhumatsoa ho 400° C ho etsa li-oxalate.

E sebelisoa ho meralo. Fast setting agent, lubricant le ente ea pele ea matla bakeng sa samente. E sebelisoa ho haha ​​seretse le tse fapa-fapaneng konkreite, potlakisa ho thatafatsa lebelo la samente, khutsufatsa ho beha nako, haholo-holo mariha kaho, ho qoba tlaase mocheso beha lebelo ke butle haholo. Fast demoulding, e le hore samente kapele kamoo ho ka khonehang ho ntlafatsa matla a kenngoa ts'ebetsong. Tšebeliso ea Calcium formate: mefuta eohle ea seretse se omeletseng, mefuta eohle ea konkreite, thepa e sa senyeheng, indasteri ea fatše, indasteri ea phepelo, ho suha matlalo.Calcium formate palo ea ho kenya letsoho le litemoso Palo ea seretse se ommeng le konkreite ka tone e ka ba ~%, 'me chelete ea tlatsetso ke %. Palo ea khalsiamo formate e ntse e eketseha butle-butle ka ho fokotseha ha mocheso, le haeba palo ea 0.3-% e sebelisoa hlabula, e tla bapala matla a pele a matla.

Ha ho futhumala, sebopeho sa sodium se senyeha ho ba hydrogen le sodium oxalate, ebe e etsa sodium carbonate. Formate ea sodium e sebelisoa haholo ho hlahisa phofo ea inshorense, oxalic acid le formic acid. Indastering ea letlalo, e sebelisoa e le asiti ts'ebetsong ea ho chesoa ha chromium, e le ntho e susumetsang le e tsitsitseng ea maiketsetso, hape e le ntho e fokotsang indastering ea khatiso le ho daea. Formate ea sodium ha e kotsi 'meleng oa motho ebile e ka khopisa mahlo, tsamaiso ea ho hema le letlalo.
