Kev siv
Formic acid, feem ntau hu ua qhov yooj yim carboxylic acid, yog cov kua tsis muaj xim nrog cov ntxhiab tsw.Nws yog ib qho tsis muaj zog electrolyte, tab sis nws cov kua aqueous yog qaug zog acidic thiab corrosive heev.Qhov no ua rau nws muaj tshuaj tua kab mob zoo heev thiab tshuaj tua kab mob, muab kev tiv thaiv zoo tiv thaiv kab mob thiab kab mob.Nws yog dav siv nyob rau hauv ntau yam kev ua kom tsis muaj menyuam hauv kev kho mob kom muaj kev nyab xeeb thiab kev noj qab haus huv ntawm cov neeg mob thiab cov kws kho mob.
Tsis tsuas yog formic acid tseem ceeb hauv kev kho mob kev lag luam, tab sis nws tseem ua lub luag haujlwm tseem ceeb hauv kev lag luam textile thiab tawv.Nws cov khoom zoo heev ua rau nws yog qhov kev xaiv nrov rau kev ua ntaub, tawv tanning thiab textile printing thiab dyeing.Tsis tas li ntawd, nws kuj tau siv dav los ua tus neeg sawv cev pub zaub ntsuab los khaws thiab tswj cov tsiaj noj kom zoo.Formic acid kuj tseem siv los ua tus neeg sawv cev kho mob saum npoo av, roj hmab additive, thiab cov kuab tshuaj muaj zog, ntxiv rau nws qhov kev ua tau zoo thiab ua tau zoo.
Tsis tas li ntawd, formic acid yog ib qho tseem ceeb ntawm cov organic synthesis.Nws yog siv los ua ib qho catalyst hauv kev tsim ntau hom esters, acridine dyes, thiab formamide series ntawm kws tshuaj intermediates.Incorporating nws rau hauv cov txheej txheem no ua kom cov synthesis ntawm cov khoom zoo thiab cov tebchaw, ua rau kev nce qib hauv kev lag luam tshuaj thiab lwm yam lag luam.
Hauv kev xaus, formic acid yog ib qho tseem ceeb tshuaj raw khoom siv nyob rau hauv ntau yam lag luam.Nws cov ntawv thov muaj xws li tshuaj tua kab mob thiab tshuaj tua kab mob mus rau textile processing thiab organic synthesis, ua rau nws muaj txiaj ntsig zoo rau txhua lub lag luam lossis lub koom haum.Nrog nws cov khoom siv tshuaj lom neeg zoo thiab muaj ntau yam, formic acid yog cov tshuaj zoo tshaj plaws rau txhua yam koj xav tau kev lag luam thiab kev lag luam.
