Isingeniso
I-Furancaryl chloride.
Ikhwalithi:
IFurancaryl chloride iwuketshezi olungenambala, olusobala olunephunga elimnandi. Incibilika kalula kuzincibilikisi ezivamile ezifana ne-ethanol, i-ether ne-benzene. Isabela emanzini yenze i-furanoic acid futhi ikhiphe igesi ye-hydrogen chloride.
Sebenzisa:
I-Furancaryl chloride ivame ukusetshenziswa njenge-reagent ebalulekile ku-organic synthesis. Ingasetshenziswa njenge-acylation reagent yokusabela kwe-acylation ukwethula amaqembu e-furancarbyl kwezinye izinhlanganisela.
Indlela:
I-Furazyl chloride ingatholakala ngokuphendula i-furanoic acid nge-thionyl chloride. I-Furancarboxylic acid ihlangana ne-thionyl chloride ku-solvent engasebenzi njenge-methylene chloride ukuze ithole i-furoformyl sulfoxide. Ngaphezu kwalokho, lapho kukhona i-thionyl chloride, i-catalyst ene-acidic (isb, i-phosphorus pentoxide) isetshenziselwa ukushisa ukusabela ukuze kukhiqizwe i-furanyl chloride.
Ulwazi Lokuphepha:
I-Furanyl chloride iyisithako esiyingozi esicasulayo futhi esibolayo. Uma uthinta isikhumba namehlo, hlambulula ngokushesha ngamanzi amaningi. Ukuhogela umhwamuko wayo kufanele kugwenywe ngesikhathi sokusebenza futhi kufanele kusetshenziswe izinto zokuvikela ezifanele ezifana nama-respirators, amagilavu kanye nezibuko uma kunesidingo. Yigcine esitsheni esingangeni moya, kude nama-oxidants namazinga okushisa aphezulu. Lapho uphatha i-furanyl chloride, izinqubo zokusebenza eziphephile kufanele zibhekwe.
