Intshayelelo
I-2,4,5-Trifluorobenzoic acid yi-organic compound. Oku kulandelayo sintshayelelo kubume bayo, ukusetyenziswa, indlela yokulungiselela kunye nolwazi lokhuseleko:
Umgangatho:
- Imbonakalo: Ayinabala ukuya kumgubo omhlophe wekristale
-Ukunyibilika: kunyibilika kancinane emanzini kwaye kunyibilika kwizinyibilikisi eziphilayo ezinje ngotywala, iiethers kunye neeketones
- Iimpawu zemichiza: Yiasidi eyomeleleyo esebenza kunye nealkalis, isinyithi kunye neentsimbi ezisebenzayo.
Sebenzisa:
- 2,4,5-Trifluorobenzoic acid isetyenziswa ikakhulu njengento ebalulekileyo ephakathi kunye ne-catalyst kwi-organic synthesis.
- Kwezinye iimpendulo ezithile, inokusetyenziswa njengomthombo we-fluoride ion kwaye ithathe inxaxheba kwiimpendulo ze-fluorination.
- Inokusetyenziswa kwakhona ekulungiseleleni ezinye iikhompawundi ze-organofluorine.
Indlela:
Kukho iindlela ezahlukeneyo zokulungiselela i-2,4,5-trifluorobenzoic acid, kwaye ilandelayo yenye yeendlela eziqhelekileyo ezisetyenziswayo:
- React benzoic acid kunye ne-aluminiyam trifluoride ukufumana i-benzoylaluminium trifluoride.
- Emva koko, i-benzoyl aluminium trifluoride ithathwa ngamanzi okanye utywala kwi-hydrolyze ukunika i-2,4,5-trifluorobenzoic acid.
Ulwazi ngoKhuseleko:
- I-2,4,5-Trifluorobenzoic acid iyacaphukisa ulusu kunye namehlo, kwaye izixhobo ezifanelekileyo zokukhusela zifunekayo xa ubamba kwaye udibanisa.
- Kwimekobume efumileyo, inokunciphisa kwaye ivelise iigesi ezinobungozi, ekufuneka ziqhutywe kwindawo enomoya ococekileyo.
- Xa ugcina kwaye uhambisa, ukudibana nee-oxidants ezinamandla, ii-asidi ezinamandla kunye nezinye izinto kufuneka zithintelwe.
- Funa unyango ngokukhawuleza ukuba utyiwe okanye uphefumle.
Iinkqubo ezifanelekileyo zokusebenza kunye namanyathelo okhuseleko kufuneka alandelwe xa kusetyenziswa naxa kusingathwa iikhemikhali, kwaye zivavanywe kwaye zilawulwe kwimeko nganye.
