Intshayelelo
I-M-chlorobenzaldehyde (ekwaziwa njenge-p-chlorobenzaldehyde) yikhompawundi ephilayo. Oku kulandelayo sintshayelelo kwiipropati zayo, ukusetyenziswa, iindlela zokuvelisa kunye nolwazi lokhuseleko:
Umgangatho:
- Imbonakalo: I-M-chlorobenzaldehyde lulwelo olungenambala ukuya kumthubi olukhanyayo kunye nevumba elibi.
- I-Solubility: Inokuthi inyibilike kwiintlobo ezininzi ze-solvents eziphilayo, ezifana ne-ethanol, i-dimethylformamide, njl., kodwa ukunyibilika kwayo kungaphantsi kunoko kwamanzi.
Sebenzisa:
- I-aldehyde yokunyanga i-agent: Ingasetyenziselwa njenge-aldehyde yokunyanga kwi-resin, iingubo kunye nezinye izinto ezidlala indima yokunyanga ukudibanisa.
Indlela:
Iindlela zamalungiselelo e-m-chlorobenzaldehyde ikakhulu zezi zilandelayo:
- I-Chlorination: Ukusabela kwekhlorini phakathi kwe-p-nitrobenzene kunye ne-cuprous chloride ivelisa i-m-chlorobenzaldehyde.
- I-Chlorination: i-p-nitrobenzene iklorini ngokuncitshiswa ukwenza i-p-chloroaniline, kwaye emva koko ngokusabela kwe-redox ukwenza i-m-chlorobenzaldehyde.
- I-Hydrogenation: i-p-nitrobenzene i-hydrogenated ukwenza i-m-chloroaniline, kwaye emva koko i-redox yenza i-m-chlorobenzaldehyde.
Ulwazi ngoKhuseleko:
- Ukuphefumla okanye ukufunxa i-m-chlorobenzaldehyde kunokubangela ityhefu, kwaye ukuphefumlelwa komphunga okanye ukutshiza emlonyeni kufuneka kuphetshwe. Funa unyango ngokukhawuleza ukuba uyatya okanye uyaphefumla.
• Kuphephe ukudibana neeoksijini, iiasidi ezomeleleyo kunye nezinye izinto eziyingozi, kwaye uphephe ukuvutha okanye ubushushu obuphezulu.
Ukusetyenziswa okuthe ngqo, nceda ulandele imimiselo efanelekileyo kunye nezikhokelo zokusebenza zokhuseleko.
