Isingeniso

2,4′-Dibromoacetophenone. Okulandelayo yisingeniso sobunjalo bayo, ukusetshenziswa, indlela yokulungiselela kanye nolwazi lokuphepha:

 

Ikhwalithi:

- Ukubukeka: I-2,4′-I-Dibromoacetophenone iyi-crystalline eqinile engenambala noma ephuzi.

- Ukunyibilika: Ingancibilika kuzincibilikisi zemvelo njenge-ethanol, i-ether, ne-benzene.

- Ukuzinza: I-2,4′-I-Dibromoacetophenone izinzile uma kuqhathaniswa nezinga lokushisa legumbi, kodwa ijwayele ukusha emazingeni okushisa aphakeme nalapho ivezwa amalangabi avulekile.

 

Sebenzisa:

- I-2,4′-I-Dibromoacetophenone ivame ukusetshenziswa njengendawo ephakathi kokuhlangana kwe-organic kuma-laboratories amakhemikhali.

- Ingasetshenziswa futhi ekuphenduleni okuthile kwe-organic synthesis, njengokusabela kwamakhemikhali e-organometallic kanye nokusabela kwe-organocatalytic.

 

Indlela:

- I-2,4′-dibromoacetophenone ngokuvamile ingahlanganiswa nge-bromination ye-benzophenone. Ngemuva kokusabela kwe-benzophenone nge-bromine, umkhiqizo ohlosiwe ungalungiswa ngesinyathelo esifanele sokuhlanza.

 

Ulwazi Lokuphepha:

- I-2,4′-Dibromoacetophenone iyingozi futhi kufanele isetshenziswe ngokuhambisana nezinqubo zokusebenza eziphephile.

- Gwema ukuthinta isikhumba, amehlo, nemigudu yokuphefumula ukuze uvimbele ukucasuka nokulimala.

- Naka izimo ezinhle zokungenisa umoya lapho uyisebenzisa futhi ugweme ukuhogela amagesi ayo.

- Le nhlanganisela kufanele igcinwe futhi isingathwe kude namalangabi avulekile kanye nemithombo yokushisa ephezulu.

  • Okwedlule:

    • Bhala umyalezo wakho lapha futhi usithumelele wona
