FORMIC ACID
Formic acid, los yog methanoic acid (HCOOH), yog qhov yooj yim carboxylic acid. Nws yog cov kua tsis muaj xim nrog cov ntxhiab tsw, thiab muaj qhov hnyav ntawm 46.03 g / mol. Nws melts ntawm 8.4 degree thiab boils ntawm 100.8 degree. Nws yog soluble heev nyob rau hauv dej thiab polar solvents zoo li methanol thiab ethanol, vim nws muaj peev xwm tsim hydrogen bonds. Nrog rau qhov ceev ntawm 1.220 g / cm³ ntawm 20 degree thiab refractive index ntawm 1.3714, nws yog denser dua dej.
Chemically, formic acid ua ob qho tib si acid thiab txo tus neeg sawv cev. Nws ionizes hauv dej los tsim hydronium thiab formate ions, thiab reacts nrog hlau zoo li sodium los tso hydrogen gas. Nws decomposes thaum rhuab los yog nyob rau hauv lub xub ntiag ntawm sulfuric acid, ua carbon monoxide thiab dej. Nws kuj tseem raug esterification nrog cawv los tsim cov esters thiab tuaj yeem ua raws li nucleophile hauv cov organic synthesis. Cov khoom no ua rau nws muaj txiaj ntsig zoo hauv ntau yam kev lag luam thiab kev sim siv.
