kodwa-3-yn-2-enye (CAS # 1423-60-5) isingeniso
3-butyne-2-enye. Oku kulandelayo sintshayelelo kubume bayo, injongo, indlela yokuvelisa, kunye nolwazi lokhuseleko:
indalo:
-Imbonakalo: 3-Butyn-2-enye lulwelo olungenambala ukuya kumthubi okhanyayo.
-Ivumba: Inevumba elimnandi elifana nelotywala neziqhamo.
-Ukunyibilika: ukunyibilika kwi-solvents ezininzi zezinto eziphilayo ezifana ne-alcohols kunye ne-ethers.
Injongo:
-3-butyne-2-enye isetyenziswa ngokubanzi kwintsimi ye-organic synthesis. Ingasetyenziswa njengento ekrwada, i-catalyst, kunye ne-solvent ye-chemical reactions, kwaye inokuthatha inxaxheba kwiindlela ezahlukeneyo ze-organic synthesis reactions, ezifana ne-nucleophilic substitution reactions kunye ne-coupling reactions.
Indlela yokuvelisa:
-Enye indlela yokulungiselela i-3-butyne-2-enye kukusabela kwe-acetone kunye ne-propargyl alcohol. Okokuqala, i-acetone iphendulwa ngokugqithisileyo kwe-sodium hydroxide ukufumana i-acetate ye-sodium, ethi emva koko iphendule nge-propargyl yotywala kumqokeleli we-oksijini ukuvelisa i-3-butyne-2-enye.
-Kukho ezinye iindlela ezahlukeneyo zokuvelisa i-3-butyne-2-enye, njengokwahlula kunye nokuhlanjululwa kwemveliso yendalo ehambelanayo, usebenzisa iindlela ze-chemical synthesis, njl.
Ulwazi lokhuseleko:
-3-Butyn-2-enye iyacaphukisa amehlo, ulusu, kunye nenkqubo yokuphefumula, kwaye kufuneka ihlanjululwe ngokukhawuleza ngamanzi xa idibene.
-Kuphephe ukudibana nee-oxidants ezinamandla, iiasidi ezinamandla, kunye neziseko eziqinileyo zokuthintela ukuphendula okuyingozi.
-Xa usebenzisa i-3-butyne-2-one, iiglavu zokukhusela iikhemikhali, iiglavu, kunye ne-mask ekhuselayo kufuneka igqitywe ukuqinisekisa iimeko ezintle zomoya.
Ezi zintshayelelo ezisisiseko malunga neepropati, ukusetyenziswa, iindlela zokulungiselela, kunye nolwazi olukhuselekileyo lwe-3-butyne-2-one. Xa usebenzisa kunye nokuphatha le khompawundi, nceda uqiniseke ukuba ulandela iinkqubo zokusebenza zokhuseleko kwaye ubhekiselele kulwazi olufanelekileyo lokhuseleko kunye neBlue Book of Chemical Substances.
