Ubungozi Nokuphepha
| Amakhodi Engozi | R28 – Kunobuthi Kakhulu uma ugwinywe R36/37/38 – Ukucasula amehlo, uhlelo lokuphefumula kanye nesikhumba. I-R11 – Ivutha Kakhulu R15 – Ukuthintana namanzi kukhulula amagesi avuthayo kakhulu U-R10 – Uyavutha |
| Incazelo Yokuphepha | 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. I-S28A - S26 – Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha. S16 – Zigcine kude nemithombo yokuthungela. S43 – Uma kusetshenziswa umlilo … (kulandela uhlobo lwempahla yokucisha umlilo ezosetshenziswa.) I-S7/8 - S7/9 - I-S24/25 - Gwema ukuthintana nesikhumba namehlo. |

kodwa-3-yn-2-one (CAS# 1423-60-5) isingeniso
3-butyne-2-one. Okulandelayo yisingeniso semvelo yayo, inhloso, indlela yokukhiqiza, kanye nolwazi lokuphepha:
imvelo:
-Ukubukeka: I-3-Butyn-2-one iwuketshezi olungenambala ukuya kokuphuzi ngokukhanyayo.
-Iphunga: Inephunga elimnandi elifana notshwala nezithelo.
-Ukunyibilika: kuncibilika kuzincibilikisi eziningi eziphilayo ezifana notshwala nama-ether.
Inhloso:
-3-butyne-2-one isetshenziswa kabanzi emkhakheni we-organic synthesis. Ingasetshenziswa njengempahla eluhlaza, i-catalyst, kanye ne-solvent yokusabela kwamakhemikhali, futhi ingabamba iqhaza ekuphenduleni okuhlukahlukene kwe-organic synthesis, njengokusabela kwe-nucleophilic substitution kanye nokuhlanganisa ukusabela.
Indlela yokukhiqiza:
-Indlela eyodwa yokulungiselela i-3-butyne-2-one iwukusabela kwe-acetone nge-propargyl alcohol. Okokuqala, i-acetone isabela nge-sodium hydroxide eyeqile ukuze ithole i-acetate ye-sodium, bese isabela nge-propargyl alcohol kumqoqi we-oxygen ukukhiqiza i-3-butyne-2-one.
-Kunezinye izindlela ezihlukahlukene zokukhiqiza i-3-butyne-2-one, njengokuhlukanisa nokuhlanza imikhiqizo yemvelo ehlobene, usebenzisa izindlela zokuhlanganisa amakhemikhali, njll.
Ulwazi lokuphepha:
-3-Butyn-2-one iyacasula amehlo, isikhumba, nesistimu yokuphefumula, futhi kufanele igezwe ngokushesha ngamanzi lapho ithintana.
-Gwema ukuthintana nama-oxidants aqinile, ama-asidi aqinile, nezisekelo eziqinile ukuze uvimbele ukusabela okuyingozi.
-Uma usebenzisa i-3-butyne-2-one, amagilavu okuvikela amakhemikhali, izibuko, kanye nemaski okuvikela kufanele kugqokwe ukuze kuqinisekiswe izimo ezinhle zokungenisa umoya.
Lezi izethulo eziyisisekelo mayelana nezakhiwo, ukusetshenziswa, izindlela zokulungiselela, nolwazi lokuphepha lwe-3-butyne-2-one. Lapho usebenzisa futhi uphatha lesi sithako, sicela uqiniseke ukuthi ulandela izinqubo zokusebenza zokuphepha futhi ubhekisele olwazini olufanele lokuphepha kanye ne-Blue Book of Chemical Substances.
