10.Fix-er for falanqaynta microscopic.Soosaarista formate.chemical nadiifinta, Formic acid waa bilaash CL, waxaa loo isticmaali karaa nadiifinta qalabka aan birta lahayn.

guban karaWaxay noqon kartaa mid lagu qallajin karo biyaha, ethanol, ether iyo glycerol, iyo inta badan dareerayaasha organic polar, iyo sidoo kale waxay leedahay milmayn gaar ah oo ku jira hydrocarbons.

Cufnaanta qaraabada ah (d204) waa 1.220.Tusmada dib-u-celinta

1.3714.Kulaylka gubashada waa 254.4 kJ/mol, heerkulka muhiimka ah waa 306.8 ℃, cadaadiska muhiimka ah waa 8.63 MPa.Dhibicda Flash 68.9 ℃ (koob furan).Cufnaanta 1.22, cufnaanta uumiga qaraabo 1.59 (hawo =1), cadaadiska uumiga buuxa (24℃) 5.33kPa.

Heerarka sare ee formic acid waxay u muuqdaan inay barafoobaan jiilaalka.

Iskudhisyada la mamnuucay: oksidat xooggan, alkali xoog leh, budada birta firfircoon.

Astaamaha khatarta ah: uumiga iyo hawadu waxay sameeyaan isku dhafka qarxa, kaas oo sababa gubasho iyo qarax haddii uu dhaco dab furan iyo tamar kuleyl sare leh.Waxay la falgashaa oksidants xooggan.

Solubility: micible biyo, aan milmin hydrocarbons, khalkhalsan ee khamriga.

Hydrocarbons iyo dawladaha gaasta, formic acid waxay u dhacdaa sida dimers oo ku xidhan bonds hydrogen.Xaaladda gaaska, isku xidhka hydrogen waxay keentaa leexasho weyn oo u dhexeeya gaaska formic acid iyo isla'egta gaasta ku habboon ee gobolka.Daareraha iyo aashitada adag ee formic waxay ka kooban yihiin unugyo formic acid ah oo joogto ah oo ku xidhan bonds hydrogen.

Formic acid waxa uu u kala go'ay CO iyo H2O iyada oo hoos imanaysa catalysis of sulfuric acid:

Sababtoo ah qaab dhismeedka gaarka ah ee formic acid, mid ka mid ah atomkiisa hydrogen wuxuu si toos ah ugu xiran yahay kooxda carboxyl.Ama waxaad u arki kartaa sida hydroxyformaldehyde.Sidaa darteed formic acid waxay leedahay labadaba aashitada iyo aldehyde labadaba.

Formic acid waxay leedahay sifooyin la mid ah inta badan asiidhyada karboksilic ee kale, inkastoo xaaladaha caadiga ah ee aashitada formic aysan samaynin acyl chloride ama anhydride.Fuuqbaxa waxay u kala jajabisaa aashitada formic oo isu beddela karbon monoxide iyo biyo.Formic acid waxay leedahay sifooyin dhimis la mid ah aldehyde.Waxay bilaabi kartaa falcelinta muraayadda qalinka ah, iyada oo yaraynaysa ion-yada qalinka ah ee ku jira amooniyamka adag ee amooniya ilaa birta qalinka ah, lafteedana waxay oksidhis ku noqotaa carbon dioxide iyo biyo:

Formic acid waa karboxilic acid kaliya ee lagu dari karo olefins.Formic acid ee ficilka asiidhka (sida sulfuric acid, hydrofluoric acid), iyo olefins waxay si dhakhso ah uga falceliyaan si ay u sameeyaan qaabab.Si kastaba ha ahaatee, falcelin dhinaca ah oo la mid ah falcelinta Koch ayaa sidoo kale dhici karta, iyada oo alaabta ay tahay karboksilic acid sare.

Qiimaha lammaane ee iskudarka qaybinta octanol/biyo: -0.54, xadka qaraxa sare% (V/V): 57.0, xadka hoose ee xadka % (V/V): 18.0.

Formic acid waa wakiil yaraynta xooggan waxaana dhici karta falcelinta muraayadda qalinka.Waa tan ugu aashitada dufanka badan ee dufanka buuxa leh, iyo kala-soocida joogtada ah waa 2.1 × 10-4.Waxay si tartiib ah u jajabisaa carbon monoxide iyo biyaha heerkulka qolka.Waxaa lagu kululeeyaa 60 ~ 80 ℃ iyadoo leh sulfuric acid si ay u qudhmiso oo ay u sii deyso carbon monoxide.Marka formic acid la kululeeyo 160 ° C, wuu burburaa si uu u sii daayo carbon dioxide iyo hydrogen.cusbada birta alkali ee formic acid waxaa lagu kululeeyaa 400 ° C si ay u sameeyaan oxalates.
