Taw qhia
Acid (acid) yog cov organic compound. Nws muaj cov tshuaj formula C6H4FNO2 thiab molecular hnyav ntawm 141.1g/mol.
Nyob rau hauv cov nqe lus ntawm xwm, acid yog ib tug dawb mus yellowish khoom. Nws muaj zog oxidation thiab corrosion, tuaj yeem yaj hauv qee cov kuab tshuaj organic xws li cawv thiab ether, tab sis solubility hauv dej tsis zoo.
Ib qho ntawm cov kev siv tseem ceeb ntawm cov kua qaub yog qhov nruab nrab hauv cov organic synthesis. Nws yog feem ntau siv rau hauv kev npaj cov tshuaj, tshuaj tua kab thiab lwm yam organic tebchaw. Tsis tas li ntawd, nws tseem tuaj yeem siv los ua lub ligand ntawm ib qho organometallic complex.
Txoj kev npaj ntawm calcium feem ntau tau txais los ntawm cov txheej txheem hauv qab no: Ua ntej, 2-fluoropyridine reacted nrog acetone thiab aluminium trichloride hauv dichloromethane los tsim 2-fluoropyridine-4-methanone. Tom qab ntawd, 2-fluoropyridine-4-methanone tau hloov mus rau fluoracid ntawm cov tshuaj tiv thaiv acid-catalyzed.
Hais txog cov ntaub ntawv kev nyab xeeb, kua qaub yog cov tshuaj organic uas yuav ua rau muaj kev phom sij rau tib neeg kev noj qab haus huv thiab ib puag ncig. Ua raws li kev nyab xeeb tsim nyog thaum tuav thiab khaws cia kom tsis txhob muaj kev sib cuag nrog daim tawv nqaij, qhov muag thiab ua pa. Cov cuab yeej tiv thaiv tus kheej xws li hnab looj tes, hnab looj tes thiab lub npog ntsej muag yuav tsum hnav thaum siv. Tsis tas li ntawd, nws yuav tsum tau muab cia rau hauv qhov chaw txias, qhuav, deb ntawm hluav taws thiab oxidizing tus neeg sawv cev. Yog tias tsim nyog, ua haujlwm hauv qhov chaw zoo ventilated. Hais txog kev pov tseg pov tseg, cov kev cai hauv zos thiab cov cai yuav tsum ua raws.
