Formic acid yog cov kua ntshiab, tsis muaj xim nrog cov ntxhiab tsw.Formic acid yog thawj zaug cais tawm ntawm cov ntsaum thiab tau muab npe tom qab Latin formica, lub ntsiab lus ntsaum.Nws yog tsim los ntawm kev ua ntawm sulfuric acid ntawm sodium formate, uas yog tsim los ntawm carbon monoxide thiab sodium hydroxide.Nws kuj yog tsim los ntawm cov khoom lag luam hauv kev tsim khoom ntawm lwm cov tshuaj xws li acetic acid.
Nws tuaj yeem cia siab tias kev siv cov tshuaj formic acid yuav nce ntxiv ntxiv vim nws hloov cov inorganic acids thiab muaj peev xwm ua lub luag haujlwm hauv lub zog tshiab.Formic acid toxicity yog ib qho kev txaus siab tshwj xeeb vim cov kua qaub yog cov tshuaj lom metabolite ntawm methanol.Khoom: FORMIC ACID yog cov kua tsis muaj xim uas muaj ntxhiab tsw.Nws yog ib qho ruaj khov corrosive, combustible, thiab hygroscopic tshuaj.Nws yog incompatible nrog H2SO4, muaj zog caustics, furfuryl cawv, hydrogen peroxide, muaj zog oxidisers, thiab bases thiab reacts nrog muaj zog tawg ntawm kev sib cuag nrog oxidising agents.
Vim yog pawg -CHO, Formic acid imparts qee yam ntawm tus cwj pwm ntawm aldehyde.Nws tuaj yeem tsim ntsev thiab ester;tuaj yeem hnov mob nrog amine los ua amide thiab tsim ester los ntawm cov tshuaj tiv thaiv ntxiv nrog unsaturated hydrocarbon ntxiv.Nws tuaj yeem txo cov tshuaj ammonia nyiaj los tsim cov iav nyiaj, thiab ua kom cov tshuaj poov tshuaj permanganate ploj mus, uas tuaj yeem siv rau kev txheeb xyuas qhov zoo ntawm formic acid.
Raws li ib tug carboxylic acid, formic acid qhia feem ntau ntawm cov tib yam tshuaj nyob rau hauv reacting nrog alkalis los ua dej soluble formate.Tab sis formic acid tsis yog ib txwm carboxylic acid raws li nws tuaj yeem hnov mob nrog alkenes los tsim cov esters.Synonyms: Acide formique; Acideformique; Acideformique (Fabkis); Acid formico; Acidoformico; Ntxiv-F; Kwas metaniowy; kwasmetaniowy
