Iphuzu lokuncibilika lalingu-105-107 °c. Incibilika ku-ethanol, i-acetone ne-propylene glycol, i-micro-encibilika emafutheni amaningi angaguquguquki, i-lg incibilika emanzini angama-72ml, inyibilika emanzini abilayo. Imikhiqizo yemvelo ikhona ku-huluba.

Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Izimpawu Eziyingozi Xi - Irritant
Amakhodi Engozi R36/37/38 – Ukucasula amehlo, uhlelo lokuphefumula kanye nesikhumba.
R43 - Ingabangela ukuzwela ngokuthinta isikhumba
Incazelo Yokuphepha S26 – Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha.
I-S36/37 – Gqoka izingubo zokuzivikela ezifanele namagilavu.
I-S24/25 - Gwema ukuthintana nesikhumba namehlo.
S22 - Ungaphefumuli uthuli.

Isingeniso

I-Methylcyclopentenolone. Okulandelayo yisingeniso sezakhiwo zayo, ukusetshenziswa kwayo, izindlela zokukhiqiza kanye nolwazi lokuphepha:

 

Ikhwalithi:

- Ukubukeka: Uketshezi olungenambala

- Iphunga: Iphunga lezithelo ezibabayo

- Ukunyibilika: Kuncibilika emanzini, otshwaleni nasezincibilikisini ze-ether

 

Sebenzisa:

 

Indlela:

- I-Methylcyclopentenolone ingalungiswa ngokusabela kokuphelelwa amandla kwamanzi otshwaleni. Ama-catalyst asetshenziswa kakhulu yi-zinc chloride, i-alumina ne-silicon oxide.

 

Ulwazi Lokuphepha:

- I-Methylcyclopentenolone iyikhemikhali enobuthi obuphansi.

- Ukunambitheka kwayo okuncane kungase kubangele ukungakhululeki kwabanye abantu, futhi ukungezwani okungaba khona noma ukucasuka kuba yingozi emehlweni nasesikhumbeni.

- Gwema ukuthintana kwamehlo nesikhumba futhi usebenzise izindlela zokuzivikela ezifana namagilavu ​​nezibuko.

- Uma uhogelwe noma udliwe, funa usizo lwezokwelapha ngokushesha.

  • Okwedlule:
  • Olandelayo:
    • Bhala umyalezo wakho lapha futhi usithumelele wona
