Formic acid yog cov kua qaub nkaus xwb hauv cov pab pawg carboxyl uas muaj zog dua li cov roj carbon ntau dua li lwm cov roj carbon monoxide, yog li cov carboxyl puppions yog ntau dua li lwm cov carboxyl acids nyob rau tib series. Formic kua qaub nyob rau hauv aqueous kev daws teeb meem yog ib qho yooj yim qaug zog, acidity coefficient (pka (ntawm 20 ℃), 1% formic acid daws Ph tus nqi yog 2.2.

Lub ntsiab siv
Formic acid yog ib qho yooj yim organic cov ntaub ntawv raw, tawv siv hauv tshuaj tua kab, tawv, zas, tshuaj thiab roj hmab. Formic acid tuaj yeem siv ncaj qha rau hauv cov ntaub ua cov ntaub, textile luam ntawv thiab cov ntaub ntawv ntsuab thiab cov roj hmab ua haujlwm thiab muaj kuab tshuaj. Nyob rau hauv cov synthic synthesis, nws yog siv los synthesize ntau tsim ntau tsim ntau tsim, acridine dyes thiab formamide series ntawm kev kho mob nruab nrab. Cov pawg tshwj xeeb muaj raws li hauv qab no:
1. Kev lag luam:
Nws tuaj yeem siv rau kev ua cov dej qab zib, aminopyrine, dooromine borneol, vitamins b1, meronidazole thiab mebendazole.
2. Tshuaj tua kab:
Yuav siv tau rau hmoov xeb, Triazolone, Triayclozole, triazolium, thev naus laus zis, tshuaj tua kab, tshuaj tua kab, dicofol ua.
3. Tshuaj Kev Lag Luam:
Cov khoom siv raw rau kev tsim cov khoom nyoos ntau tsim, pentaquatherol, nopentanediol, epoxy epexy, penyyl choybe, pleev xim redin.
4. Tawv Kev Lag Luam:
Siv ua tawv tanning npaj, daehing cov neeg sawv cev thiab nruab nrab tus neeg sawv cev.
5. Roj av lag luam:
Rau kev ua cov roj hmab cov roj hmab coavulants, roj hmab antioxidant raug.
6. Kuaj cov COL ntau lawm. Tshuaj lom neeg cov tshuaj tiv thaiv:
7. Cerium, rhenium thiab tungsten raug sim. Cov amines uas muaj ntxhiab tsw qab, amines thiab metrehoxy pawg tau tshuaj xyuas. Tus txheeb ze lub cev hnyav thiab lub ntsej muag ua kom huv thiab siv methoxyl tau txiav txim siab. Siv raws li kev tshuaj xyuas hauv tsom tsom rau me me.
8. Cov tshuaj acid thiab nws cov kua aqueous tuaj yeem tshem tawm ntau cov hlau, hydroxides thiab nws tuaj yeem siv ua cov tshuaj ntxuav tu tshuaj lom neeg. Formic acid tsis muaj chloride ions thiab tuaj yeem siv rau kev tu cov khoom uas muaj cov ntaub ntawv hlau stainless hlau.
9. Siv los npaj kua, Papelruit, qhob cij, cheese, cheese, cream, qab zib, qab zib thiab whiskey, rum tsw. Cov khoom noj muaj kuab kawg yog li 1 txog 18 mg / kg.
10. Lwm tus: tseem tuaj yeem tsim cov khoom siv zas xim, cov fiber ntau thiab cov neeg sawv cev tshuaj tiv thaiv, tshuab yas, cov tshuaj ntxiv thiab txo cov neeg sawv cev.
