Isingeniso
4,4′-I-Dichlorobenzophenone iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sobunjalo bayo, ukusetshenziswa, indlela yokulungiselela kanye nolwazi lokuphepha:
Ikhwalithi:
1. Ukubukeka: I-4,4′-I-Dichlorobenzophenone iyi-crystalline eqinile engenambala ukuya kokukhanya okuphuzi.
3. Ukuncibilika: Iyancibilika kwezinye izinyibilikisi zemvelo, njenge-ethers notshwala, kodwa ayincibiliki emanzini.
Sebenzisa:
1. Ama-Chemical reagents: I-4,4′-dichlorobenzophenone isetshenziswa kabanzi njenge-reagent ku-organic synthesis, ikakhulukazi ukusabela ekuhlanganiseni kwezinhlanganisela ezinuka kamnandi.
2. Izibulala-zinambuzane: Ingasetshenziswa futhi njengendawo ephakathi ekuhlanganiseni ezinye izibulala-zinambuzane.
Indlela:
Ukulungiswa kwe-4,4′-dichlorobenzophenone kuvame ukwenziwa ngalezi zinyathelo ezilandelayo:
1. I-Benzophenone isabela ne-thionyl chloride phambi kwe-n-butyl acetate ukuze inikeze i-2,2′-diphenylketone.
Okulandelayo, i-2,2′-diphenyl ketone isabela ne-thionyl chloride phambi kwe-sulfuric acid ukuze yakhe i-4,4′-dichlorobenzophenone.
Ulwazi Lokuphepha:
1. I-4,4′-I-Dichlorobenzophenone kufanele ithathe izinyathelo zokuphepha ezidingekayo ngesikhathi sokuphatha nokugcina ukugwema ukuthintana nesikhumba, amehlo nomlomo.
2. Gqoka amagilavu okuzivikela, izibuko kanye nemaski uma usebenzisa.
3. Isebenze endaweni engenawo umoya futhi ugweme ukuhogela umhwamuko wayo.
4. Esimeni lapho uthintana ngephutha noma ukumunca, funa usizo lwezokwelapha ngokushesha futhi ulethe ilebula noma ishidi ledatha yokuphepha yalo nto.
