Poizoni Olekanitsidwa ndi mafuta a malasha ndipo amagwiritsidwa ntchito popanga
coumarone-indene utomoni. Utoto uwu umagwiritsidwa ntchito mu utoto, guluu, etc.
ndipo amaloledwa mu phukusi chakudya. Zochepa zimadziwika za kawopsedwe
ya benzofuran kwa anthu koma poizoni woopsa pakuyesa
nyama zimakhudza chiwindi ndi impso kulephera. Kusatha kwa nyama
zimakhudza chiwindi, impso, mapapo, ndi m'mimba.
Ulamuliro wa moyo wonse (oral administration) unayambitsa khansa

Mawu Oyamba

Oxyindene (C9H6O2) ndi mankhwala okhala ndi mphete za benzene ndi mphete za benzofuran. Zotsatirazi ndizofotokozera za katundu, ntchito, njira zokonzekera ndi chidziwitso cha chitetezo cha oxyyindene:

 

Ubwino:

Maonekedwe: Oxyinden ndi yopanda mtundu mpaka yopepuka yachikasu yolimba.

Kusungunuka: Oxyinden imatha kusungunuka mu zosungunulira zambiri, koma sizisungunuka m'madzi.

 

Gwiritsani ntchito:

Oxindene itha kugwiritsidwanso ntchito ngati chowonjezera ku photosensitizers ndi polima stabilizers.

 

Njira:

Oxyinden ikhoza kukonzedwa ndi makutidwe ndi okosijeni a benzofuran ndi benzofuranone. Kukonzekera kwapadera kungaphatikizepo njira zovuta mu kaphatikizidwe ka organic, zomwe nthawi zambiri zimafunikira kugwiritsa ntchito okosijeni pansi pamikhalidwe yoyenera.

 

Zambiri Zachitetezo:

Oxyinden imatengedwa ngati chinthu chotetezeka pakagwiritsidwe ntchito kake, koma imafunikirabe kutsata njira zogwirira ntchito mu labotale komanso kupanga mafakitale.

Pogwira ntchito ya oxindene, muyenera kuvala zida zodzitetezera zoyenera monga magolovesi, magalasi, ndi zovala zodzitetezera.

Pewani kukhudzana ndi khungu ndi maso, ndipo pewani kupuma kapena kumeza oxyyindene.

Oxyindene iyenera kusungidwa mu chidebe chotchinga mpweya kutali ndi kuyatsa ndi okosijeni.
