Isingeniso
I-M-chlorobenzaldehyde (ephinde yaziwe ngokuthi i-p-chlorobenzaldehyde) iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sezakhiwo zayo, ukusetshenziswa kwayo, izindlela zokukhiqiza kanye nolwazi lokuphepha:
Ikhwalithi:
- Ukubukeka: I-M-chlorobenzaldehyde iwuketshezi olungenambala ukuya kokuphuzi olukhanyayo olunephunga elimnandi.
- I-Solubility: Ingancibilika kuma-solvents amaningi e-organic, njenge-ethanol, i-dimethylformamide, njll., kodwa ukuncibilika kwayo kuphansi kunamanzi.
Sebenzisa:
- I-aldehyde yokwelapha i-ejenti: Ingasetshenziswa njenge-ejenti yokwelapha i-aldehyde kuma-resin, ama-coatings nezinye izinto ukuze idlale indima yokwelapha okuxhumanisa.
Indlela:
Izindlela zokulungiselela i-m-chlorobenzaldehyde ikakhulukazi zimi kanje:
- I-Chlorination: Ukusabela kwe-chlorination phakathi kwe-p-nitrobenzene ne-cuprous chloride kukhiqiza i-m-chlorobenzaldehyde.
- I-Chlorination: i-p-nitrobenzene igcotshwa ngokuncishiswa ukuze yakhe i-p-chloroaniline, bese ngokusabela kwe-redox ukwenza i-m-chlorobenzaldehyde.
- I-Hydrogenation: i-p-nitrobenzene i-hydrogenated ukuze yakhe i-m-chloroaniline, bese i-redox yenza i-m-chlorobenzaldehyde.
Ulwazi Lokuphepha:
- Ukuhogela umoya noma ukumunca i-m-chlorobenzaldehyde kungabangela ubuthi, futhi ukuhogela umhwamuko noma amachaphazelo emlonyeni kufanele kugwenywe. Thola usizo lwezempilo ngokushesha uma udla noma uhogela umoya.
- Gwema ukuthintana nama-oxidants, ama-asidi aqinile nezinye izinto eziyingozi, futhi ugweme ukuthungela noma amazinga okushisa aphezulu.
Ukuze usebenzise okuthile, sicela ulandele imithethonqubo efanele kanye nemihlahlandlela yokusebenza kokuphepha.
