Mawu Oyamba

Methylcyclopentenolone. Zotsatirazi ndizofotokozera za katundu wake, ntchito, njira zopangira ndi chitetezo:

 

Ubwino:

- Maonekedwe: Madzi opanda mtundu

- Fungo: Kununkhira kwa zipatso zokometsera

- Kusungunuka: Kusungunuka m'madzi, mowa ndi zosungunulira za ether

 

Gwiritsani ntchito:

 

Njira:

- Methylcyclopentenolone akhoza kukonzekera ndi chothandizira kuchepa madzi m'thupi anachita mowa. Zomwe zimagwiritsidwa ntchito kwambiri ndi zinc chloride, alumina ndi silicon oxide.

 

Zambiri Zachitetezo:

- Methylcyclopentenolone ndi mankhwala otsika kawopsedwe.

- Kakomedwe kake kakang'ono kamasokoneza anthu ena, ndipo zomwe zingawachitikire kapena kuyabwa kumabweretsa chiopsezo m'maso ndi pakhungu.

- Pewani kukhudzana ndi maso ndi khungu ndipo gwiritsani ntchito njira zodzitetezera monga magolovesi ndi magalasi.

- Mukakowetsedwa kapena kulowetsedwa, pitani kuchipatala mwamsanga.
