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 ​​namagilavuza uma kunesidingo. Yigcine esitsheni esingangeni moya, kude nama-oxidants namazinga okushisa aphezulu. Lapho uphatha i-furanyl chloride, izinqubo zokusebenza eziphephile kufanele zibhekwe.
