Isingeniso
I-3,4-Epoxytetrahydrofuran iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwale nhlanganisela:
Izakhiwo: I-3,4-Epoxytetrahydrofuran iwuketshezi olungenambala olunephunga lama-phenols. Iyakwazi ukuvutha futhi ingenza izingxube eziqhumayo ngomoya. Inhlanganisela iyancibilika emanzini futhi izinzile ngaphansi kwezimo ezine-asidi.
Ukusetshenziswa: I-3,4-Epoxytetrahydrofuran isetshenziswa kabanzi ekuphenduleni okuningi ku-organic synthesis kanye nemboni yamakhemikhali. Ingasetshenziswa njenge-solvent, i-catalyst kanye ne-intermediate.
Indlela yokulungiselela: I-3,4-epoxytetrahydrofuran ivame ukuhlanganiswa ngokusabela kwe-epoxidation. Indlela evamile iwukusabela i-stannous tetrachloride nge-tetrahydrofuran ukukhiqiza i-epoxide. Ukusabela ngokuvamile kwenzeka ekamelweni lokushisa futhi kudinga ukungezwa kwe-acidic catalyst ukuze kube lula ukusabela.
Kuyinto evuthayo futhi kufanele igwenywe ukuthintana namalangabi avulekile kanye namazinga okushisa aphezulu. Gwema ukuhogela amagesi noma ukuthinta isikhumba namehlo ngesikhathi sokusebenza. Kufanele isetshenziswe endaweni enomoya omuhle futhi impahla yokuzivikela efanele efana namagilavu nezingubo zamehlo zokuzivikela kufanele zigqokwe. Ngaphezu kwalokho, idinga ukugcinwa esitsheni esingangenisi umoya, kude nemithombo yokushisa namalangabi avulekile. Uma kwenzeka kuvuza, yimise ngokushesha futhi ugweme ukungena endle noma engaphansi. Uma uthintana ngephutha noma uhogele umoya, funa usizo lwezempilo ngokushesha.
