| Amakhodi Engozi | I-R60 - Ingase iphazamise inzalo U-R61 - Ingabangela ukulimala enganeni engakazalwa R20/21 – Kuyingozi ngokuhogela umoya nangokuthinta isikhumba. R25 – Kunobuthi uma ugwinywe R63 – Ingozi engaba khona yokulimala enganeni engakazalwa R36/37/38 – Ukucasula amehlo, uhlelo lokuphefumula kanye nesikhumba. I-R11 – Ivutha Kakhulu R67 – Izihwamuko zingadala ukozela kanye nesiyezi R65 – Iyingozi: Ingadala umonakalo wamaphaphu uma igwinyisiwe R48/20 - |
| Incazelo Yokuphepha | S53 – Gwema ukuchayeka – thola imiyalelo ekhethekile ngaphambi kokuyisebenzisa. S16 – Zigcine kude nemithombo yokuthungela. S36/37/39 – Gqoka izingubo zokuzivikela ezifanele, amagilavu kanye nokuvikela iso/ubuso. S45 – Uma kwenzeka ingozi noma uzizwa ungaphilile, funa iseluleko sezokwelapha ngokushesha (bonisa ilebula noma nini lapho kunokwenzeka.) I-S37/39 – Gqoka amagilavu afanelekile kanye nokuvikela iso/ubuso I-S28A - S26 – Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha. I-S62 – Uma igwinyisiwe, ungabangeli ukuhlanza; funa iseluleko sezokwelapha ngokushesha futhi ubonise lesi sitsha noma ilebula. I-S36/37 – Gqoka izingubo zokuzivikela ezifanele namagilavu. |

Isingeniso
I-3-Bromopropyne, eyaziwa nangokuthi i-1-bromo-2-propyne, iyinhlanganisela yezinto eziphilayo. Okulandelayo isingeniso esifushane sezakhiwo zayo, ukusetshenziswa kwayo, izindlela zokukhiqiza kanye nolwazi lokuphepha:
Ikhwalithi:
- Inomthamo ophansi, onenani elicishe libe ngu-1.31 g/mL.
I-3-Bropropyne inephunga elimnandi.
- Ingancibilika kwezinye izincibilikisi eziphilayo njenge-ethanol ne-ether.
Sebenzisa:
- I-3-Broproyne isetshenziswa kakhulu njenge-reagent ekuphenduleni kwe-organic synthesis, isibonelo ingabamba iqhaza ekuphenduleni kwe-metal-catalyzed cross-coupling for synthesis of organic compounds.
- Ingasetshenziswa futhi njengesiqalo sama-alkynes, isb ekuhlanganiseni ama-alkynes noma amanye ama-alkynes asebenzayo.
Indlela:
- I-3-Bromopropyne ingatholwa ngokusabela kwe-bromoacetylene ne-ethyl chloride ngaphansi kwezimo ze-alkali.
- Lokhu kwenziwa ngokuxuba i-bromoacetylene ne-ethyl chloride bese wengeza inani elithile le-alkali (njenge-sodium carbonate noma i-sodium bicarbonate).
- Ekupheleni kokusabela, i-3-bromopropynne ehlanzekile itholakala ngokuxutshwa nokuhlanzwa.
Ulwazi Lokuphepha:
- I-3-Bropropyne iwubuthi futhi iyacika edinga ukuthi kugqokwe okokusebenza okufanele kokuzivikela komuntu (i-PPE) uma usebenza.
- Kufanele igweme ukuthintana nama-oxidants, ama-alkali aqinile, nama-acids aqinile ukuze kugwenywe ukusabela okuyingozi.
- Ukuthobela izinqubo zokusebenza zokuphepha ezifanele ngesikhathi sokusetshenziswa nokugcinwa.
- Uma ubamba i-3-bromopropyne, qinisekisa ukuthi umoya ungena kahle futhi ugweme ukuhogela umhwamuko wayo noma ukuthintana nesikhumba namehlo.
