Ubungozi Nokuphepha
| Amakhodi Engozi | U-R10 – Uyavutha R25 – Kunobuthi uma ugwinywe R36/38 – Ukucasuka emehlweni nasesikhumbeni. R36/37/38 – Ukucasula amehlo, uhlelo lokuphefumula kanye nesikhumba. R24/25 - |
| Incazelo Yokuphepha | S26 – Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha. S45 – Uma kwenzeka ingozi noma uzizwa ungaphilile, funa iseluleko sezokwelapha ngokushesha (bonisa ilebula noma nini lapho kunokwenzeka.) S36/37/39 – Gqoka izingubo zokuzivikela ezifanele, amagilavu kanye nokuvikela iso/ubuso. S16 – Zigcine kude nemithombo yokuthungela. |

Isingeniso esifushane
I-3-butyne-2-ol, eyaziwa nangokuthi i-butynol, iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sezakhiwo zayo, ukusetshenziswa kwayo, izindlela zokukhiqiza kanye nolwazi lokuphepha:
Ikhwalithi:
- Ukubukeka: 3-butyn-2-ol uketshezi olungenambala.
- Ukunyibilika: Incibilika otshwaleni obungamanzi ne-ether, kuyilapho ukunyibilika kwayo emanzini kuphansi.
- Iphunga: 3-butyn-2-ol inephunga elimnandi.
Sebenzisa:
- Ukwakheka kwamakhemikhali: kungasetshenziswa njengendawo ephakathi kokuhlangana kwe-organic ukuze kulungiswe ezinye izinhlanganisela eziphilayo.
- I-Catalyst: I-3-butyn-2-ol ingasetshenziswa njenge-catalyst yokusabela okuthile.
- I-solvent: Ngenxa yokuncibilika kwayo okuhle kanye nobuthi obuphansi uma kuqhathaniswa, ingasetshenziswa njengesixazululi.
Indlela:
- I-3-Butin-2-ol ingalungiswa ngokusabela kwe-butyne ne-ether. Ukusabela kwenziwa phambi kotshwala futhi kwenziwa emazingeni okushisa aphansi.
- Enye indlela yokulungiselela iwukusabela kwe-butyne ne-acetaldehyde. Lokhu kusabela kufanele kwenziwe ngaphansi kwezimo ze-acidic.
Ulwazi Lokuphepha:
- I-3-Butyn-2-ol iwuketshezi oluvuthayo futhi kufanele igcinwe kude namalangabi avulekile kanye namazinga okushisa aphezulu.
- Thatha izinyathelo zokuphepha lapho usebenzisa izibuko zokuzivikela, kuhlanganise nezibuko zokuzivikela namagilavu.
- Lapho uthinta isikhumba noma amehlo, geza ngokushesha ngamanzi amaningi.
- Gwema ukuhogela umhwamuko wawo futhi uwusebenzise endaweni engenawo umoya.
- Ukulahlwa kukadoti kufanele kuhambisane nemithetho yendawo yendawo.
