Intshayelelo

I-2-Chloro-5-fluorobenzoic acid yi-organic compound. Oku kulandelayo sintshayelelo kubume bayo, ukusetyenziswa, indlela yokulungiselela kunye nolwazi lokhuseleko:

 

Umgangatho:

- Imbonakalo: Ayinambala ukuya kwiikristale ezityheli ezikhanyayo okanye umgubo wekristale.

- Ukunyibilika: ukunyibilika kwizinyibilikisi eziphilayo, ukunyibilika kancinane emanzini.

 

Sebenzisa:

- I-2-Chloro-5-fluorobenzoic acid idla ngokusetyenziswa njengendawo ephakathi kwi-organic synthesis.

- Inokusetyenziswa kwakhona njenge-organic synthesis reagent kunye ne-catalyst.

 

Indlela:

I-2-Chloro-5-fluorobenzoic acid idla ngokulungiswa ngu:

I-2-chloro-5-fluorobenzyl utywala iphendulwa nge-sodium hydroxide (NaOH) okanye i-potassium hydroxide (KOH) ukufumana ityuwa yesodium ehambelanayo okanye ityuwa ye-potassium.

I-acidified yi-hydrochloric acid ukuvelisa i-2-chloro-5-fluorobenzoic acid.

 

Ulwazi ngoKhuseleko:

- I-2-Chloro-5-fluorobenzoic acid yinto enokutsha kwaye kufuneka igwenywe ekudibaneni ne-oxidizing agents enamandla okanye i-oxygen.

- Nxiba izixhobo ezifanelekileyo zokukhusela, ezinjengeeglavu, iindondo, nempahla yokukhusela, xa uphethe okanye uphethe.

- Kuphephe ukuphefumla uthuli lwayo okanye isisombululo kwaye usebenze kwindawo engena umoya.

- Gcina kude kumaqondo obushushu aphezulu, umlilo, kunye nelanga elithe ngqo, kwaye ugcine isikhongozeli sivalwe ngokuqinileyo.

  • Ngaphambili:
  • Okulandelayo:
    • Bhala umyalezo wakho apha kwaye uwuthumele kuthi
