Isingeniso

I-M-chlorofluorobenzene iyinhlanganisela yezinto eziphilayo.

 

Ikhwalithi:

- I-M-chlorofluorobenzene iwuketshezi olungenambala ukuya kokuphuzi okuphaphathekile olunephunga elimnandi elingavamile.

- Inomthamo omkhulu futhi iyancibilika kuzincibilikisi eziningi eziphilayo, njenge-ethanol, i-ether, njll.

- Ibola emazingeni okushisa aphezulu, ikhiqize amagesi anobuthi.

 

Sebenzisa:

- Ingasetshenziswa futhi njengesincibilikisi, okokuhlanza kanye nesithako.

 

Indlela:

Kunezindlela ezimbili eziyinhloko zokulungiselela i-m-chlorofluorobenzene:

Indlela yegesi ye-fluorine: igesi ye-fluorine idluliselwa engxubeni yokusabela ye-chlorobenzene, futhi i-m-chlorofluorobenzene yenziwa ngaphansi kwesenzo se-catalyst.

Indlela ye-Industrial synthesis: ukusabela kwe-deuteration kwenzeka ebukhoneni be-catalyst nge-benzene ne-chloroform ukukhiqiza i-m-chlorofluorobenzene.

 

Ulwazi Lokuphepha:

- I-M-chlorofluorobenzene iwuketshezi oluguquguqukayo olukwazi ukuvutha futhi lungabangela umlilo lapho luvezwe ilangabi elivulekile noma izinga lokushisa eliphezulu.

- Kuyinto enobuthi engase ibangele ukucasuka nokulimala uma ihlangana nesikhumba noma uma ihogelwa.

- Uma usebenzisa noma ulungiselela i-m-chlorofluorobenzene, landela izimiso zokuphepha eziqinile futhi uthathe izinyathelo zokuzivikela ezifanele, njengokugqoka amagilavu ​​okuzivikela, izibuko kanye nemaski.
