Taw qhia
O-chlorotoluene yog ib qho organic compound. Nws yog cov kua xim tsis muaj xim nrog lub aroma tshwj xeeb thiab soluble hauv feem ntau cov kuab tshuaj organic.
Kev siv lub ntsiab ntawm o-chlorotoluene yog raws li cov kuab tshuaj thiab cov tshuaj tiv thaiv nruab nrab. Nws tuaj yeem siv rau hauv alkylation, chlorination thiab halogenation cov tshuaj tiv thaiv hauv cov organic synthesis. O-chlorotoluene kuj tseem siv rau hauv kev tsim cov ntawv luam tawm, cov xim, cov yas, roj hmab, thiab cov dyes.
Muaj peb txoj hauv kev tseem ceeb rau kev npaj o-chlorotoluene:
1. O-chlorotoluene tuaj yeem npaj tau los ntawm cov tshuaj tiv thaiv ntawm chlorosulfonic acid thiab toluene.
2. Nws kuj tuaj yeem tau txais los ntawm cov tshuaj tiv thaiv ntawm chloroformic acid thiab toluene.
3. Tsis tas li ntawd, o-chlorotoluene kuj tuaj yeem tau txais los ntawm cov tshuaj tiv thaiv ntawm o-dichlorobenzene thiab methanol nyob rau hauv lub xub ntiag ntawm ammonia.
1. O-chlorotoluene yog khaus khaus thiab muaj kuab lom, kev sib cuag ntawm daim tawv nqaij thiab nqus tau pa yuav tsum zam. Cov hnab looj tes tiv thaiv, tsom iav thiab cov khoom tiv thaiv ua pa yuav tsum tau hnav thaum ua haujlwm.
2. Tsis txhob sib cuag nrog cov oxidants muaj zog thiab muaj zog acids kom tsis txhob muaj kev phom sij txaus ntshai.
3. Nws yuav tsum tau muab cia rau hauv qhov chaw uas muaj qhov cua zoo thiab kom deb ntawm cov nplaim taws thiab qhov kub thiab txias.
4. Cov khib nyiab yuav tsum muab pov tseg raws li cov kev cai hauv zos thiab yuav tsum tsis txhob muab pov tseg rau hauv ib puag ncig ntuj.
