Intshayelelo
2,3-Dichlorobenzoyl chloride. Oku kulandelayo sintshayelelo kwiipropati zayo, ukusetyenziswa, iindlela zokuvelisa kunye nolwazi lokhuseleko:
Umgangatho:
- Imbonakalo: 2,3-Dichlorobenzoyl chloride kuyinto elulwelo ukukhanya ukukhanya yellow.
- Ukunyibilika: I-2,3-Dichlorobenzoyl chloride iyanyibilika kwii-solvents eziphilayo ezifana ne-ethers kunye ne-alcohol, kodwa ayinyibiliki emanzini.
Sebenzisa:
- I-2,3-Dichlorobenzoyl chloride yikhompawundi ebalulekileyo ephakathi kwaye isetyenziswa rhoqo kwiimpendulo ze-organic synthesis.
- I-2,3-Dichlorobenzoyl chloride ingasetyenziselwa njenge-acylation reagent yokuguqula amaqela e-hydroxyl kumaqela e-acyl.
- Ikwasetyenziswa ekulungiseleleni izixhobo zokwenza irabha kunye nezixhobo zepolymer, phakathi kwezinye iindawo.
Indlela:
- I-2,3-Dichlorobenzoyl chloride inokufumaneka ngokuphendula i-2,3-dichlorobenzoic acid kunye ne-thionyl chloride. Iimeko zokusabela zifudunyezwa kwiatmosfera engasebenziyo de i-reactants iyanyibilika, kwaye i-thionyl chloride yongezwa kancinci.
-I-reaction equation imi ngolu hlobo lulandelayo:
C6H4(Cl)COOH + SO2Cl2 → C6H4(Cl)C(O)Cl + H2SO4
Ulwazi ngoKhuseleko:
- I-2,3-Dichlorobenzoyl chloride yi-organic compound enetyhefu ethile. Ukuvezwa okanye ukuphefumla kwikhompawundi kunokubangela ukucaphuka kunye nomonakalo eluswini, emehlweni, nakwindlela yokuphefumla.
- Xa usebenzisa i-2,3-dichlorobenzoyl chloride, umoya olungileyo kufuneka uqheliselwe kwaye kusetyenziswe izixhobo ezifanelekileyo zokuzikhusela ezifana neeglavu, iiglasi zokhuseleko, kunye neemaski zokhuselo.
- Ngexesha lokugcinwa kunye nokuphathwa, iinkqubo zokukhusela iikhemikhali kufuneka zithotyelwe ngokungqongqo, kunye nemithombo yomlilo kunye nezinto ezinokutsha kufuneka zigcinwe kude.
- Ukuba i-2,3-dichlorobenzoyl chloride iginyiwe okanye ibonakaliswe ngempazamo, funa unyango ngokukhawuleza kwaye uzise ulwazi malunga nekhompawundi.
