Isingeniso
I-2-butynyl-1-ol, eyaziwa nangokuthi i-butynol, iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-2-butyn-1-ol:
Izakhiwo: Iwuketshezi olungenambala olunephunga elimnandi elikhethekile.
- I-2-Butyn-1-ol iyancibilika emanzini nasezincibilikilweni eziningi eziphilayo njenge-ethanol ne-ether.
- Kuyinhlanganisela yotshwala enamaqembu asebenzayo e-alkyne anamakhemikhali athile otshwala nama-alkynes.
Sebenzisa:
- I-2-butyn-1-ol isetshenziswa kakhulu ku-organic synthesis njengendlela yokusabela emaphakathi noma i-reagent. Ingasetshenziswa njengento yokuqala, i-solvent, noma i-catalyst for synthesis of organic compounds.
- Ingasetshenziswa futhi ekulungiseni ezinye izinhlanganisela ezifanayo njengama-ether, ama-ketone, nama-etherketone.
Indlela:
- I-2-Butyno-1-ol ingalungiswa ngokusabela kwe-hydrogenated acetone alcohol kanye ne-chloroform.
- Enye indlela evamile yokulungiselela iwukuba uhlanganise i-ethyl mercaptan ne-acetone phambi kwe-amino catalyst, bese uthola i-2-butyn-1-ol ngokufaka i-mercury chloride.
Ulwazi Lokuphepha:
- I-2-Butin-1-ol into ecasulayo engase ibangele ukucasuka kanye nokulimala kwamehlo, isikhumba, kanye nendlela yokuphefumula.
- Impahla yokuzivikela efanele njengamagilavu okuzivikela kanye nezibuko kufanele kugqokwe lapho uphathwa.
- Inhlanganisela inomthelela olinganiselwe endaweni ezungezile, kodwa kufanele kuthathwe ukunakekelwa ukuze kuhambisane nemithetho efanele yezemvelo lapho kusingathwa futhi kuchithwa.
