Intshayelelo

Umgangatho:

- Imbonakalo: I-Benzoaldehyde ilulwelo olungenambala, kodwa iisampulu eziqhelekileyo zorhwebo zityheli.

- Ivumba: Inevumba elimnandi.

 

Indlela:

I-Benzoaldehyde inokulungiswa nge-oxidation ye-hydrocarbons. Iindlela zokulungiselela eziqhelekileyo ezisetyenziswayo ziquka ezi zilandelayo:

- I-Oxidation esuka kwi-phenol: Xa kukho i-catalyst, i-phenol i-oxidized yi-oksijini emoyeni ukuze yenze benzaldehyde.

- I-Catalytic oxidation esuka kwi-ethylene: Xa kukho i-catalyst, i-ethylene i-oxidized yi-oksijini emoyeni ukuze yenze benzaldehyde.

 

Ulwazi ngoKhuseleko:

- Inobuthi obuphantsi kwaye ayibangeli iingxaki zempilo ezinzulu kubantu phantsi kweemeko eziqhelekileyo zokusetyenziswa.

- Kuyacaphukisa emehlweni kunye nolusu, kwaye amanyathelo okukhusela afana neeglavu kunye neeglavu kufuneka athathwe xa ubamba.

- Ukuvezwa ixesha elide kwiqondo eliphezulu le-benzaldehyde vapor kunokubangela ukucaphuka kwindlela yokuphefumula kunye nemiphunga, kwaye ukuphefumla ixesha elide kufuneka kugwenywe.

- Xa uphatha i-benzaldehyde, kufuneka kuthathelwe ingqalelo umlilo kunye neemeko zomoya ukuze ugweme ukuvezwa komlilo ovulekileyo okanye ukushisa okuphezulu.
