Isingeniso
2,3-Dichlorobenzoyl chloride. Okulandelayo yisingeniso sezakhiwo zayo, ukusetshenziswa kwayo, izindlela zokukhiqiza kanye nolwazi lokuphepha:
Ikhwalithi:
- Ukubukeka: I-2,3-Dichlorobenzoyl chloride iwuketshezi olungenambala oluphuzi olukhanyayo.
- Ukunyibilika: I-2,3-Dichlorobenzoyl chloride iyancibilika kuzincibilikisi zemvelo njenge-ethers notshwala, kodwa ayincibiliki emanzini.
Sebenzisa:
- 2,3-Dichlorobenzoyl chloride iyinhlanganisela ebalulekile ephakathi futhi ivame ukusetshenziswa ekuphenduleni kwe-organic synthesis.
- 2,3-Dichlorobenzoyl chloride ingasetshenziswa futhi njenge-acylation reagent yokuguqula amaqembu e-hydroxyl abe amaqembu e-acyl.
- Ibuye isetshenziswe ekulungiseleleni izinsiza zokucubungula irabha nezinto ze-polymer, phakathi kweminye imikhakha.
Indlela:
- 2,3-Dichlorobenzoyl chloride ingatholakala ngokusabela ku-2,3-dichlorobenzoic acid nge-thionyl chloride. Izimo zokusabela ziyashisiswa endaweni engasebenzi kuze kube yilapho okusabelayo kuncibilika, futhi i-thionyl chloride yengezwe kancane kancane.
- I-equation yokusabela imi kanje:
C6H4(Cl)COOH + SO2Cl2 → C6H4(Cl)C(O)Cl + H2SO4
Ulwazi Lokuphepha:
- 2,3-Dichlorobenzoyl chloride iyinhlanganisela yemvelo enobuthi obuthile. Ukuchayeka noma ukuhogela inhlanganisela kungabangela ukucasuka ngisho nokulimala esikhumbeni, emehlweni, nasendleleni yokuphefumula.
- Uma usebenzisa i-2,3-dichlorobenzoyl chloride, kufanele kwenziwe umoya omuhle futhi kufanele kusetshenziswe izinto zokuzivikela ezifanele ezifana namagilavu, izibuko zokuphepha, namamaski okuzivikela.
- Ngesikhathi sokugcina nokuphatha, izinqubo zokuphepha kwamakhemikhali kufanele zilandelwe ngokuqinile, futhi imithombo yomlilo nezinto ezivuthayo kufanele zigcinwe kude.
- Uma i-2,3-dichlorobenzoyl chloride igwinywa noma ivezwa ngephutha, funa usizo lwezokwelapha ngokushesha futhi ulethe ulwazi mayelana nenhlanganisela.
