Formic acid yeyona acid kuphela kwiqela carboxyl edityaniswe athom yehydrogen, iathom yehydrogen athom repulsive electron force incinane kakhulu kuneqela hydrocarbon, ukuze carboxyl carbon atom electron density ingaphantsi kunezinye carboxyl acid, nangenxa conjugation. umphumo, i-athomu ye-carboxyl ye-oksijini kwi-electron ithambekele kwikhabhoni, ngoko i-asidi yomelele kunezinye ii-carboxyl acids kuthotho olufanayo.I-asidi ye-formic kwisisombululo esinamanzi yi-asidi ebuthakathaka elula, i-acidity coefficient (pKa) = 3.75 (at 20℃), i-1% yesisombululo se-asidi ye-asidi i-pH ixabiso yi-2.2.

Ukusetyenziswa kweMveliso
Usetyenziso oluphambili
Iasidi yeFormic yenye yezinto ezisisiseko zemichiza ekrwada, esetyenziswa kakhulu kwizibulali-zinambuzane, ufele, iidayi, amayeza kunye namashishini erabha.I-asidi ye-formic ingasetyenziswa ngokuthe ngqo ekusetyenzweni kwelaphu, ufele olulukiweyo, ushicilelo olulukiweyo kunye nokudaya kunye nokugcinwa kokutya okuluhlaza, kwaye ingasetyenziswa njenge-arhente yonyango lomphezulu wesinyithi, i-rubber encedisayo kunye nesinyibilikisi semizi-mveliso.Kwi-organic synthesis, isetyenziselwa ukudibanisa iifomathi ezahlukeneyo, idayi ye-acridine kunye nochungechunge lwe-formamide lwezonyango.Iindidi ezithile zezi zilandelayo:
1. Ishishini lamachiza:
Ingasetyenziselwa ukusetyenzwa kwe-caffeine, i-aminopyrine, i-aminophylline, i-theobromine borneol, i-vitamin B1, i-metronidazole kunye ne-mebendazole.
2. Ushishino lwezitshabalalisi:
ingasetyenziselwa irust engumgubo, i-triazolone, i-tricyclozole, i-triazole, i-triazolium, i-triazolium, i-polybulozole, i-tenobulozole, i-insecticide, i-dicofol processing.
3. Ishishini lemichiza:
izinto eziluhlaza zokwenza iifomathi ezahlukeneyo, i-formamide, i-pentaerythritol, i-neopentanediol, i-oyile ye-epoxy soybean, i-epoxy octyl soybean oleate, i-valeryl chloride, i-remover yepende kunye ne-phenolic resin.
4. ishishini lethwathwa:
isetyenziswa njengamalungiselelo okusukwa kwesikhumba, ii-agent ezitshabalalisayo kunye nee-neutraizing agents.
5. ishishini lerabha:
ukusetyenzwa kwe-coagulants yerabha yendalo, ukwenziwa kwerabha ye-antioxidant.
6. imveliso yaselabhoratri CO. Chemical reaction formula:
7. I-Cerium, i-rhenium kunye ne-tungsten ivavanywa.Ii-amine eziphambili ezivumbayo, ii-amine zesibini kunye namaqela e-methoxy avavanywa.Ubunzima bemolekyuli kunye neqela le-crystalline solvent methoxyl lamiselwa.Isetyenziswe njenge-fixative kuhlalutyo lwe-microscopic.
8. i-asidi ye-formic kunye nesisombululo sayo samanzi sinokunyibilika ezininzi zetsimbi, i-oxides zetsimbi, i-hydroxides kunye neetyuwa, i-formate ebangelwayo inokuchithwa emanzini, ngoko ingasetyenziselwa njenge-agent yokucoca imichiza.I-asidi ye-formic ayinayo i-ion ye-chloride kwaye ingasetyenziselwa ukucoca izixhobo eziqukethe izinto zensimbi ezingenasici.
9. esetyenziselwa ukulungisa iapile, ipapaya, ijackfruit, isonka, itshizi, itshizi, ikhrimu kunye nezinye incasa ezityiwayo kunye newhisky, incasa yerum.Ugxininiso ekutyeni kokugqibela okunambithekileyo malunga ne-1 ukuya kwi-18 mg / kg.
10. Abanye: banokwenza i-daying mordant, i-fiber kunye ne-ejenti yokudaya iphepha, i-ejenti yonyango, i-plasticizer, ukugcinwa kokutya, izongezo zokutya kwezilwanyana kunye nee-arhente zokunciphisa.
