Matou te gaosiaSu'a Fomue ala i le Methyl Formate sili ona maualuga

tekinolosi. Muamua, o le Methyl Formate e gaosia mai le CO ma Methanol faatasi ai ma le gaioiga o le catalyst. I lalo o le vevela ma le mamafa, o le Methyl Formate e faʻafefeteina ile Formic Acid. Ole mama maualalo ole Formic Acidsolution ole a faʻatumauina i mea maualuluga e faʻafetaui ai manaʻoga eseese-

tulaga o tagata fa'atau.

10.Fix-er for microscopic analysis.Producing formate.chemical cleaningagent, Formic acid e leai se CL, e mafai ona faʻaaogaina mo le faʻamamāina o mea faʻapipiʻi uʻamea.

Mumu. E mafai ona faʻafefiloi ma vai, ethanol, eter ma glycerol, ma le tele o solu faʻalaʻau polar, ma e iai foʻi se solubility patino i hydrocarbons.

Ole va'aiga (d204) ole 1.220. Fa'ailoga fa'afofo

1.3714. O le vevela vevela o le 254.4 kJ / mol, o le vevela vevela o le 306.8 ℃, ma le mamafa mamafa o le 8.63 MPa. Ipu moli 68.9 ℃ (ipu tatala). Malosi 1.22, va'aiga va'ava'a 1.59 (ea =1), mamafa ausa (24℃) 5.33kPa.

Ole maualuga ole acid formic e masani ona malolo ile taumalulu.

Fa'asaina fa'atasi: malosi oxidant, malosi alkali, malosi pauta u'amea.

Uiga mata'utia: o le ausa ma le ea e fausia ai se paluga pa, lea e mafua ai le mu ma le pa i le tulaga o le afi matala ma le malosi o le vevela. E tali atu i mea fa'ama'i malolosi.

Solubility: fa'afefiloi ma le vai, e le mafai ona fa'afefeteina i le hydrocarbons, fa'afefiloi i le ava malosi.

I le hydrocarbons ma le kasa states, formic acid e tupu mai e pei o dimer e fusifusia e fusi hydrogen. I le tulaga kasa, o le fa'apipi'iina o le hydrogen e maua ai se va'aiga tele i le va o kasa acid formic ma le fa'atusa lelei o le kasa o le setete. O le sua ma le sua malosi o lo'o i ai mole mole mole oona fa'aauau o lo'o fa'apipi'iina e fa'amauga hydrogen.

O le formic acid e pala i le CO ma le H2O i lalo o le catalysis o le sulfuric acid concentrated:

Ona o le fausaga faʻapitoa o le formic acid, o se tasi o ana hydrogen atoms e fesoʻotaʻi saʻo i le vaega carboxyl. Pe mafai fo'i ona e va'ai iai ose hydroxyformaldehyde. O lea la, o le formic acid e iai mea uma e lua o le acid ma le aldehyde.

O le fomic acid e tutusa mea e pei o le tele o isi carboxylic acids, e ui i tulaga masani ole formic acid e le fausia ai se acyl chloride po'o le anhydride. O le fa'amamāina o le vai e fa'apala ai le acid formic i le carbon monoxide ma le vai. O le formic acid e tutusa mea e fa'aitiitia ai le aldehydes. E mafai ona amataina se tali fa'ata siliva, fa'aitiitia ai ion siliva i ions lavelave ammonia siliva i u'amea siliva, ma o ia lava e oxidized i carbon dioxide ma vai:

O le formic acid e na'o le carboxylic acid e mafai ona fa'aopoopo i olefins. O le acid formic i le gaioiga a acids (e pei o le sulfuric acid, hydrofluoric acid), ma olefins e vave ona tali atu e fai ai formates. Ae ui i lea, o se itu e tali tutusa ma le tali Koch e mafai foi ona tupu, faatasi ai ma le oloa o se maualuga maualuga o le carboxylic acid.

Paiga tau o le octanol/vaega vai: -0.54, pito i luga pa % (V/V) : 57.0, tapulaa pa maualalo % (V/V): 18.0.

O le formic acid ose malosi fa'aitiitiga fa'aitiitiga ma e mafai ona tupu fa'a'a'ai fa'ata siliva. O le sili ona acidic i ga'o ga'o tumu, ma o le dissociation tumau o le 2.1 × 10-4. E malepe malie ile carbon monoxide ma vai ile vevela ole potu. E vevela i le 60 ~ 80 ℃ faʻatasi ai ma le sulfuric acid faʻapitoa e pala ma faʻasaʻo le carbon monoxide. Pe a fa'avevela le su'ega formic i luga a'e o le 160°C, e pala e fa'amatu'u mai ai le kaponi dioxide ma le hydrogen. O masima u'amea alkali o formic acid e fa'avevela i le 400 ° C e fai ai oxalate.
