Mawu Oyamba

Ubwino:

- Maonekedwe: Benzoaldehyde ndi madzi opanda mtundu, koma zitsanzo zodziwika bwino zamalonda ndi zachikasu.

- Fungo: Lili ndi fungo lonunkhira bwino.

Njira:

Benzoaldehyde ikhoza kukonzedwa ndi makutidwe ndi okosijeni a ma hydrocarbon. Njira zokonzekera zomwe zimagwiritsidwa ntchito kwambiri ndi izi:

- Oxidation kuchokera ku phenol: Pamaso pa chothandizira, phenol imapangidwa ndi okosijeni mumlengalenga kupanga benzaldehyde.

- Catalytic oxidation kuchokera ku ethylene: Pamaso pa chothandizira, ethylene imapangidwa ndi okosijeni mumlengalenga kupanga benzaldehyde.

Zambiri Zachitetezo:

- Ili ndi kawopsedwe kakang'ono ndipo sichimayambitsa mavuto akulu azaumoyo kwa anthu omwe amagwiritsidwa ntchito bwino.

- Zimakwiyitsa maso ndi khungu, ndipo njira zodzitetezera monga magolovesi ndi magalasi ziyenera kutengedwa mukakhudza.

- Kuwonetsedwa kwa nthawi yayitali ndi mpweya wochuluka wa benzaldehyde kungayambitse kupsa mtima kwa kupuma ndi m'mapapo, ndipo kupuma kwanthawi yayitali kuyenera kupewedwa.

- Pogwira ntchito ya benzaldehyde, chisamaliro chiyenera kutengedwa pamoto ndi mpweya wabwino kuti musatengeke ndi malawi otseguka kapena kutentha kwambiri.
