Formic acid waa aashitada kaliya ee kooxda carboxyl ee ku xiran atomka hydrogen, hydrogen atomka elektarooniga ah ee naxaasta ah ayaa aad uga yar kooxda hydrocarbon, sidaa darteed cufnaanta carbon carbon atomi cufnaanta ayaa ka hooseeya asiidhyada kale ee carboxyl, iyo sababta oo ah saamaynta isku dhafka ah, atamka karboxyl oxygen atamka elektarooniga ah ayaa aad ugu janjeera carbon kaarboonka kale, marka loo eego aashitada kale. Formic acid ee xalka aqueous waa asiidh daciif ah oo fudud, iskudarka aysiidhka (pKa) = 3.75 (at 20 ℃), 1% formic acid xal pH qiimaha waa 2.2.

Isticmaalka Alaabta
Isticmaalka ugu weyn
Formic acid waa mid ka mid ah alaabta ceeriin ee kiimikada dabiiciga ah, oo si weyn loogu isticmaalo sunta cayayaanka, maqaarka, midabada, daawooyinka iyo warshadaha caaga ah. Formic acid waxaa si toos ah loogu isticmaali karaa farsamaynta dharka, maqaar maqaar, daabacaadda dharka iyo dheehidda iyo kaydinta quudinta cagaaran, iyo sidoo kale waxaa loo isticmaali karaa sida wakiilka daaweynta dusha biraha, caag kaabayaal ah iyo dareere warshadaha. Isku-dhafka dabiiciga ah, waxaa loo isticmaalaa in lagu soo saaro qaabab kala duwan, midabyo acridine ah iyo taxane formamide ee dhexdhexaadiyeyaasha caafimaadka. Qaybaha gaarka ah waa sida soo socota:
1. Warshadaha dawooyinka:
Waxaa loo isticmaali karaa habaynta caffeine, aminopyrine, aminophylline, theobromine borneol, vitamin B1, metronidazole iyo mebendazole.
2. warshadaha sunta cayayaanka:
waxaa loo isticmaali karaa miridhku budada, triazolone, tricyclozole, triazole, triazolium, triazolium, polybulozole, tenobulozole, cayayaanka, dicofol processing.
3. Warshadaha Kiimikada:
alaabta ceeriin ee lagu soo saaro qaabab kala duwan, formamide, pentaerythritol, neopentanediol, epoxy soybean oil, epoxy octyl soybean oleate, valeryl chloride, rinjiga saaraya iyo resin phenolic.
4. warshadaha hargaha:
loo isticmaalo sida diyaarinta harag-maqaarka, wakiilada dilidda iyo wakiilada dhexdhexaadinta.
5. Warshadaha caagga ah:
loogu talagalay ka-hortagga xuubka caagga dabiiciga ah, wax-soo-saarka antioxidant-ka caagga ah.
6. wax soo saarka shaybaadhka CO. formula falcelinta kiimikada:
7. Cerium, rhenium iyo tungsten waa la tijaabiyay. Amiinada aasaasiga ah ee udgoonka, aminyada sare iyo kooxaha methoxy ayaa la baadhay. Miisaanka molecular ee qaraabada ah iyo kooxda methoxyl dareeraha crystalline ayaa la go'aamiyay. Loo isticmaalo sidii hagaajinta falanqaynta microscopic.
8. formic acid iyo xalkeeda aqueous waxay milmi kartaa biraha badan, oksaydhyada birta, hydroxides iyo cusbada, qaabka ka soo baxa waxaa lagu milmi karaa biyaha, sidaas darteed waxaa loo isticmaali karaa sidii kiimiko nadiifin ah. Formic acid kuma jiraan ion koloriin waxaana loo isticmaali karaa nadiifinta qalabka ay ku jiraan walxo birta aan la taaban karin.
9. waxaa loo isticmaalaa in lagu diyaariyo tufaax, babaay, jackfruit, rooti, jiis, jiis, kareem iyo dhadhanka kale ee la cuni karo iyo wiski, dhadhan rum. Isku-duubnaanta cuntada dhadhanka ugu dambeysa waa 1 ilaa 18 mg/kg.
10. kuwa kale: waxay sidoo kale soo saari karaan midabaynta mordant, fiber iyo wakiilka dheeha waraaqaha, wakiilka daaweynta, balaastiigga, ilaalinta cuntada, lagu daro quudinta xoolaha iyo wakiilada yaraynta.
