Intshayelelo

2,4′-Dibromoacetophenone. Oku kulandelayo sintshayelelo kubume bayo, ukusetyenziswa, indlela yokulungiselela kunye neenkcukacha zokhuseleko:

 

Umgangatho:

- Imbonakalo: 2,4′-Dibromoacetophenone is a colorless or yellowish crystalline solid.

- Ukunyibilika: Inokunyibilika kwizinyibilikisi eziphilayo ezifana ne-ethanol, i-ether, kunye ne-benzene.

- Ukuzinza: I-2,4′-I-Dibromoacetophenone izinzile kwiqondo lokushisa lokushisa, kodwa ilungele ukutsha kwiqondo lokushisa eliphezulu kwaye xa ibonakaliswe kumlilo ovulekileyo.

 

Sebenzisa:

- 2,4′-Dibromoacetophenone isetyenziswa ngokuqhelekileyo njengendawo ephakathi kwi-organic synthesis kwiilebhu zamachiza.

- Isenokusetyenziswa kwizinto ezithile ze-organic synthesis reactions, ezifana ne-organometallic chemical reactions kunye ne-organocatalytic reactions.

 

Indlela:

- I-2,4′-dibromoacetophenone ngokuqhelekileyo inokuqulunqwa nge-bromination ye-benzophenone. Emva kokusabela kwe-benzophenone nge-bromine, imveliso ekujoliswe kuyo ingalungiswa ngesinyathelo esifanelekileyo sokucoca.

 

Ulwazi ngoKhuseleko:

- 2,4′-Dibromoacetophenone iyingozi kwaye kufuneka isetyenziswe ngokuhambelana neenkqubo zokusebenza ezikhuselekileyo.

- Kuphephe ukudibana nolusu, amehlo, kunye nendlela yokuphefumla ukuthintela ukucaphuka kunye nokwenzakala.

- Nika ingqalelo kwiimeko ezilungileyo zokungenisa umoya xa uyisebenzisa kwaye ugweme ukuphefumla iigesi zayo.

- Le khompawundi kufuneka igcinwe kwaye iphathwe kude namadangatye avulekileyo kunye nemithombo yobushushu obuphezulu.
