Intshayelelo

I-4,4′-i-Dichlorobenzophenone yi-organic compound. Oku kulandelayo sintshayelelo kubume bayo, ukusetyenziswa, indlela yokulungiselela kunye nolwazi lokhuseleko:

 

Umgangatho:

1. Imbonakalo: 4,4′-Dichlorobenzophenone is a colorless light yellow crystalline solid.

3. Ukunyibilika: Inyibilika kwezinye izinyibilikisi eziphilayo, ezinjengeethers kunye ne-alcohol, kodwa ayinyibiliki emanzini.

 

Sebenzisa:

1. I-Chemical reagents: I-4,4′-dichlorobenzophenone isetyenziswa ngokubanzi njenge-reagent kwi-organic synthesis, ngokukodwa kwiimpendulo kwi-synthesis ye-aromatics compounds.

2. Izibulali-zinambuzane: Isenokusetyenziswa njengendawo ephakathi ekudityanisweni kwezinye izibulali-zinambuzane.

 

Indlela:

Ukulungiswa kwe-4,4′-dichlorobenzophenone idla ngokuqhutywa ngala manyathelo alandelayo:

1. I-Benzophenone iphendula kunye ne-thionyl chloride phambi kwe-n-butyl acetate ukunika i-2,2'-diphenylketone.

Emva koko, i-2,2'-diphenyl ketone iphendula kunye ne-thionyl chloride phambi kwe-asidi ye-sulfuric ukwenza i-4,4'-dichlorobenzophenone.

 

Ulwazi ngoKhuseleko:

1. I-4,4′-Dichlorobenzophenone kufuneka ithathe amanyathelo okhuseleko ayimfuneko ngexesha lokuphatha kunye nokugcinwa ukuze ugweme ukudibanisa nolusu, amehlo kunye nomlomo.

2. Nxiba iiglavu zokukhusela, izibuko kunye nemaski xa usebenzisa.

3. Sebenza kwindawo engenamoya kwaye uphephe ukuphefumla imiphunga yayo.

4. Kwimeko yokudibana okanye ukuginya ngengozi, funa unyango ngokukhawuleza kwaye uze neleyibhile okanye i-data sheet yokhuseleko lwaloo nto.

  • Ngaphambili:
  • Okulandelayo:
    • Bhala umyalezo wakho apha kwaye uwuthumele kuthi
