Isingeniso

I-1,2-Epibutane iyinhlanganisela yezinto eziphilayo. Iwuketshezi olungenambala olunephunga elimnandi ekamelweni lokushisa. Okulandelayo yisingeniso sezakhiwo zayo eziyinhloko, ukusetshenziswa, izindlela zokukhiqiza kanye nolwazi lokuphepha:

 

Izakhiwo: Iwuketshezi oluvuthayo olungakha ingxube eqhumayo nomoya-mpilo. Ibuye ibe namandla esikhumbeni esicasulayo kanye ne-eye irritater.

 

Sebenzisa:

I-1,2-Butyloxide isetshenziswa kakhulu ekuhlanganiseni kwe-organic, imithi, izibulala-zinambuzane kanye nezingubo. Kuyinto ephakathi ebalulekile futhi ivame ukusetshenziswa ku-organic synthesis ukulungisa ezinye izinhlanganisela, ezifana notshwala, ama-ketone, ama-ether, njll.

 

Indlela:

I-1,2-Epibutane ingalungiswa ngokusabela kwe-octanol ne-hydrogen peroxide. Indlela eqondile yokulungiselela ukusabela i-octanol nge-hydrogen peroxide phambi kwe-catalyst efanele ukukhiqiza i-1,2-epoxybutane.

 

Ulwazi Lokuphepha:

I-1,2-Epibutane iyinto eyingozi enezingozi ezingaba khona njengokucasuka kanye ne-teratogenicity. Kufanele kuqashelwe ukugwema ukuthinta isikhumba kanye nokuhogela umhwamuko waso ngesikhathi sokusetshenziswa, futhi kufanele kunikezwe izinto zokuzivikela ezifanele njengamagilavu, izibuko, nokuvikela ukuphefumula uma kunesidingo. Ngesikhathi sokugcina nokuphatha, ukunakekelwa kufanele kuthathwe ukuvimbela ukuvutha kanye nogesi omile. Gwema ukuxubana nama-oxidants aqinile nama-asidi ukugwema ukusabela okuyingozi. Lapho kulahlwa udoti, imithetho nemithetho yendawo kufanele ilandelwe.

  • Okwedlule:
