Taw qhia
Acid (acid) yog cov organic compound. Nws cov qauv tshuaj yog C6H4FNO2 thiab nws qhov hnyav molecular yog 141.10g / mol.
Nyob rau hauv cov nqe lus ntawm xwm, acid yog ib tug dawb khoom. Nws yog ruaj khov ntawm chav tsev kub, tab sis tej zaum yuav decompose ntawm qhov kub thiab txias los yog nyob rau hauv kev sib cuag nrog ib tug ignition qhov chaw. Nws yog soluble hauv dej thiab ntau yam organic solvents xws li ethanol thiab dimethylformamide.
Acid muaj qee yam kev siv hauv kev tshawb fawb tshuaj thiab tshuaj. Raws li qhov nruab nrab ntawm cov organic synthesis, nws tuaj yeem siv rau hauv kev sib txuas ntawm lwm cov tebchaw, xws li cov tshuaj lom neeg lom neeg, tshuaj thiab dyes. Nws kuj tuaj yeem siv los ua ligand rau kev hloov pauv hlau catalyzed cov tshuaj tiv thaiv.
nyob rau hauv txoj kev npaj, muaj ntau yam hluavtaws txoj kev ntawm acid. Ib txoj hauv kev yog kom tau txais cov khoom lag luam los ntawm kev ua pa pyridine nrog hydrogen fluoride, ua raws li carboxylation.
Hais txog kev nyab xeeb cov ntaub ntawv, kua qaub yog cov organic compound, thiab koj yuav tsum tau xyuam xim rau kev nyab xeeb thaum siv nws. Nws tuaj yeem ua rau khaus thiab puas rau qhov muag, tawv nqaij thiab ua pa. Hnav cov khoom tiv thaiv tsim nyog xws li hnab looj tes, tsom iav thiab qhov ncauj qhov ntswg thaum ua haujlwm. Tom qab kev kho mob, kev saib xyuas yuav tsum tau them sai sai rau kev tu thiab tshem tawm cov khib nyiab kom tsis txhob muaj kuab paug rau ib puag ncig.
