Intshayelelo
4-(trifluoromethoxy)benzaldehyde, ekwaziwa njenge-p-(trifluoromethoxy)benzaldehyde. Oku kulandelayo sintshayelelo kwiipropati, ukusetyenziswa, iindlela zokulungiselela, kunye nolwazi lokhuseleko lwekhompawundi:
Umgangatho:
- Imbonakalo: Ayinambala ukuya kwiikristale ezityheli ezikhanyayo
-Ukunyibilika: Inyibilika kwizinyibilikisi eziphilayo ezifana ne-methanol, i-ethanol kunye ne-methylene chloride, i-soluble kancinane emanzini.
Sebenzisa:
- 4-(i-Trifluoromethoxy)benzaldehyde isetyenziswa ikakhulu kwintsimi ye-organic synthesis njenge-intermediate ekudityanisweni kwezinye iikhompawundi.
- Kwintsimi ye-pesticides, ingasetyenziselwa ukwenza i-insecticide, i-herbicides, kunye ne-fungicides, phakathi kwabanye.
Indlela:
- Ukulungiswa kwe-4-(trifluoromethoxy) benzaldehyde idla ngokufunyanwa nge-esterification ye-fluoromethanol kunye ne-p-toluic acid, ilandelwa yi-redox reaction ye-esters.
Ulwazi ngoKhuseleko:
- 4-(i-Trifluoromethoxy) benzaldehyde kufuneka igwenywe ekudibaneni nee-oxidizing agents ezinamandla kunye ne-acids ezomeleleyo ukuphepha ukuphendula ngobundlobongela.
- Amanyathelo okukhusela umntu afana neeglavu zekhemikhali kunye nezibuko kufuneka zisetyenziswe ukuphepha ukudibanisa nolusu kunye namehlo.
- Le yikhemikhali enokuba yingozi ekufuneka isetyenziswe kwaye igcinwe ngokuhambelana neenkqubo ezifanelekileyo zokusebenza ezikhuselekileyo kwaye ziphathwe kwindawo engena umoya.
- Xa uphethe kwaye ulahla inkunkuma, thobela imithetho kunye nemimiselo efanelekileyo yendawo.
