Isingeniso
I-4-Bromo-n-butyne iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sezakhiwo zayo, ukusetshenziswa kwayo, izindlela zokukhiqiza kanye nolwazi lokuphepha:
Ikhwalithi:
- I-4-bromo-n-butyne iwuketshezi olungenambala olunephunga elimnandi neliphunga.
- I-4-Bromor-n-butyne iyinhlanganisela yemvelo eguquguqukayo esabela nomoya-mpilo emoyeni.
Sebenzisa:
- I-4-Bromo-n-butyne ivame ukusetshenziswa njengendawo ephakathi ku-organic synthesis futhi ibamba iqhaza ekuphenduleni okuhlukahlukene kwamakhemikhali e-organic.
- Ingasetshenziswa ekulungiseleleni ezinye izinhlanganisela ze-organobromine ezifana ne-ethyl bromide, njll.
- Inephunga elibabayo futhi elibabayo futhi kwesinye isikhathi isetshenziswa njengesinye sezithako ezifuthweni zokulwa nempisi.
Indlela:
- I-4-Bromo-n-butyne ingatholwa ngokusabela kwe-4-bromo-2-butyne ngama-bromide ensimbi ye-alkali njenge-sodium bromide.
- Lokhu kusabela kukhiqiza ukushisa okuningi futhi kudinga ukupholiswa ukulawula izinga lokushisa lokusabela.
Ulwazi Lokuphepha:
- I-4-Bromo-butyne iyacasula futhi kufanele igwenywe ukuthintana nesikhumba, amehlo kanye nolwelwesi lwamafinyila.
- Amagilavu, izibuko, nezingubo zokuzivikela kufanele zigqokwe lapho usebenzisa futhi uphatha i-4-bromo-n-butyne.
- Gwema ukuhogela umhwamuko wayo futhi uqinisekise ukuthi ukuhlinzwa kwenziwa endaweni enomoya omuhle.
- I-4-Bromo-n-butyne iyinto evuthayo futhi kufanele igcinwe kude nomlilo nemithombo yokushisa futhi igcinwe endaweni epholile, eyomile.
- Lapho kusingathwa futhi kulahlwa i-4-bromo-n-butyne, izivumelwano zokusebenza zokuphepha ezifanele kufanele zilandelwe.
