Formic acid ndi asidi okhawo mu gulu la carboxyl olumikizidwa ndi atomu ya hydrogen, mphamvu ya hydrogen atomu yonyansa ma elekitironi ndi yaying'ono kwambiri kuposa gulu la hydrocarbon, kotero kuti kachulukidwe ka carboxyl carbon atomu ma elekitironi ndi otsika kuposa ma carboxyl acids, komanso chifukwa cha conjugation. Zotsatira zake, atomu ya okosijeni ya carboxyl pa electron imakonda kwambiri carbon, kotero asidiyo ndi wamphamvu kuposa ma carboxyl acids omwewo.Formic acid mu njira yamadzimadzi ndi asidi ofooka ochepa, acidity coefficient (pKa) = 3.75 (pa 20 ℃), 1% formic acid solution pH mtengo ndi 2.2.

Formic acid ndi imodzi mwazinthu zopangira organic zopangira mankhwala, zomwe zimagwiritsidwa ntchito kwambiri popanga mankhwala ophera tizilombo, zikopa, utoto, mankhwala ndi mafakitale amphira.Formic asidi angagwiritsidwe ntchito mwachindunji pokonza nsalu, pofufuta zikopa, nsalu kusindikiza ndi utoto ndi wobiriwira chakudya chosungira, ndipo angagwiritsidwe ntchito ngati zitsulo pamwamba mankhwala wothandizira, mphira wothandiza ndi zosungunulira mafakitale.Mu kaphatikizidwe ka organic, amagwiritsidwa ntchito popanga mitundu yosiyanasiyana, utoto wa acridine ndi ma formamide angapo apakati azachipatala.Magulu enieni ndi awa:
1. Makampani opanga mankhwala:
Angagwiritsidwe ntchito pokonza tiyi kapena khofi, aminopyrine, aminophylline, theobromine borneol, vitamini B1, metronidazole ndi mebendazole.
2. makampani ophera tizilombo:
angagwiritsidwe ntchito pa ufa dzimbiri, triazolone, tricyclozole, triazole, triazolium, triazolium, polybulozole, tenobulozole, insecticide, dicofol processing.
3. Makampani opanga mankhwala:
zopangira zopangira mitundu yosiyanasiyana, formamide, pentaerythritol, neopentanediol, epoxy soya mafuta, epoxy octyl soya oleate, valeryl chloride, chochotsa utoto ndi phenolic resin.
4. makampani achikopa:
amagwiritsidwa ntchito ngati zokometsera zikopa, zowotcha komanso zoziziritsira.
5. makampani amphira:
kwa processing wa zachilengedwe mphira coagulants, mphira antioxidant kupanga.
6. kupanga labotale CO. Chemical reaction formula:
7. Cerium, rhenium ndi tungsten amayesedwa.Ma amine oyambira onunkhira, ma amine achiwiri ndi magulu a methoxy adawunikidwa.Kulemera kwa maselo ndi gulu la crystalline solvent methoxyl linatsimikiziridwa.Amagwiritsidwa ntchito ngati fixative pakusanthula kwa microscopic.
8. formic acid ndi njira yake yamadzimadzi amatha kupasuka zitsulo zambiri, oxides zitsulo, hydroxides ndi mchere, chifukwa formate akhoza kusungunuka m'madzi, kotero angagwiritsidwe ntchito ngati mankhwala kuyeretsa wothandizila.Formic acid ilibe ma chloride ayoni ndipo imatha kugwiritsidwa ntchito poyeretsa zida zomwe zili ndi zitsulo zosapanga dzimbiri.
9. amagwiritsidwa ntchito popanga apulo, papaya, jackfruit, mkate, tchizi, tchizi, kirimu ndi zina zokometsera zodyera ndi kachasu, kukoma kwa ramu.Mlingo wa chakudya chomaliza chokoma ndi pafupifupi 1 mpaka 18 mg/kg.
10. ena: amathanso kupanga utoto wa mordant, fiber ndi pepala lodaya wothandizira, wothandizira mankhwala, plasticizer, kusunga chakudya, zowonjezera zakudya zanyama ndi zochepetsera.
