Taw qhia
Acid yog cov organic compound nrog cov tshuaj formula C7H7NO2. Nws yog cov xim tsis muaj xim crystalline, soluble hauv dej thiab cov kuab tshuaj organic.
Acid muaj ntau yam kev siv. Nws tuaj yeem siv los ua ib qho nruab nrab hauv cov organic synthesis rau kev npaj ntawm lwm cov tebchaw. Nws tuaj yeem ua raws li ligand rau organometallic complexes thiab koom nrog cov tshuaj tiv thaiv catalytic. Tsis tas li ntawd, nws kuj tuaj yeem siv rau hauv kev sib xyaw ntawm qee yam tshuaj.
Muaj ntau txoj hauv kev los npaj ICT. Ib txoj hauv kev yog synthesis los ntawm kev kho thiab oxidation ntawm toluene. Tshwj xeeb, toluene yog thawj reacted nrog acetaldehyde nyob rau hauv lub xub ntiag ntawm ib tug oxidizing neeg sawv cev los tsim 3-methyl-4-picolinic acid ester, uas yog ces raug rau cov kua qaub hydrolysis kom tau lub hom phiaj cov khoom.
Kev nyab xeeb ntawm cov kua qaub yog siab, tab sis qee qhov kev nyab xeeb tseem yuav tsum tau ua tib zoo saib. Hnav cov khoom tiv thaiv tsim nyog xws li tsom iav thiab hnab looj tes thaum ua haujlwm. Tsis txhob nqus cov plua plav thiab roj thiab tsis txhob kov cov tawv nqaij. Thaum lub sijhawm khaws cia thiab kev thauj mus los, yuav tsum tau them nyiaj rau cov khoom pov thawj noo noo, tiv thaiv hluav taws thiab tiv thaiv tawg. Nyob rau hauv cov ntaub ntawv ntawm kev huam yuaj los yog tiv tauj, nrhiav kev kho mob tam sim ntawd thiab nqa cov ntaub ntawv kev nyab xeeb ntawm cov khoom no mus rau lub tsev kho mob.
