Isingeniso

Ikhwalithi:

- Ukubukeka: I-Benzoaldehyde iwuketshezi olungenambala, kodwa amasampula okuhweba avamile aphuzi.

- Iphunga: Inephunga elimnandi.

 

Indlela:

I-Benzoaldehyde ingalungiswa nge-oxidation yama-hydrocarbons. Izindlela zokulungiselela ezivame ukusetshenziswa zihlanganisa okulandelayo:

- I-Oxidation evela ku-phenol: Lapho kukhona i-catalyst, i-phenol ikhishwa umoya-mpilo emoyeni ukuze yakhe i-benzaldehyde.

- I-Catalytic oxidation evela ku-ethylene: Lapho kukhona i-catalyst, i-ethylene i-oxidized yi-oxygen emoyeni ukuze yakhe i-benzaldehyde.

 

Ulwazi Lokuphepha:

- Inobuthi obuphansi futhi ayibangeli izinkinga zempilo ezimbi kubantu ngaphansi kwezimo ezijwayelekile zokusetshenziswa.

- Kuyacasula emehlweni nasesikhumbeni, futhi izinyathelo zokuzivikela ezifana namagilavu ​​kanye nezibuko kufanele zithathwe uma uthinta.

- Ukuchayeka isikhathi eside kumhwamuko we-benzaldehyde omningi kungase kubangele ukucasuka kwendlela yokuphefumula nasemaphashini, futhi ukuhogela isikhathi eside kufanele kugwenywe.

- Lapho uphatha i-benzaldehyde, kufanele kuqashelwe izimo zomlilo nezokungenisa umoya ukuze kugwenywe ukuchayeka emalangabi avulekile noma amazinga okushisa aphezulu.
