Omaka bomkhiqizo

Amakhodi Engozi U-R10 – Uyavutha
R34 – Ibangela ukusha
R42/43 - Ingabangela ukuzwela ngokuhogela umoya nangokuthinta isikhumba.
R36 – Ukucasuka emehlweni
Incazelo Yokuphepha S23 – Ungawuphefumuli umhwamuko.
S26 – Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha.
S36/37/39 – Gqoka izingubo zokuzivikela ezifanele, amagilavu ​​kanye nokuvikela iso/ubuso.
S45 – Uma kwenzeka ingozi noma uzizwa ungaphilile, funa iseluleko sezokwelapha ngokushesha (bonisa ilebula noma nini lapho kunokwenzeka.)
S25 – Gwema ukuthintana namehlo.
S16 – Zigcine kude nemithombo yokuthungela.

Isingeniso

I-2,4-difluorobenzylbromide iyinhlanganisela ye-organic enefomula yamakhemikhali ethi C7H5BrF2. Iwuketshezi olungenambala olunephunga elinamandla. Okulandelayo incazelo yezinye izakhiwo, ukusetshenziswa, izindlela kanye nolwazi lokuphepha lwe-2,4-difluorobenzylbromide:

 

Imvelo:

-Ukubukeka: I-2,4-difluorobenzylbromide iwuketshezi olungenambala.

-I-Solubility: Ingancibilika nge-organic solvents, njenge-ethanol, i-chloroform ne-dimethylformamide.

 

Sebenzisa:

-2,4-difluorobenzylbromide ingasetshenziswa njengendawo ephakathi ku-organic synthesis futhi isetshenziswe ekuhlanganiseni ezinye izinhlanganisela.

-Ingasetshenziswa futhi njengento eluhlaza emkhakheni wezibulala-zinambuzane kanye nemithi.

 

Indlela:

-2,4-difluorobenzylbromide ngokuvamile ilungiswa ngokusabela i-2,4-difluorobenzoic acid nge-bromine.

-Indlela ethile yokulungiselela ingalungisa izimo zokusabela kanye nama-reagents asetshenziswa njengoba kudingeka.

 

Ulwazi Lokuphepha:

- I-2,4-difluorobenzylbromide iyacasula futhi idinga ukunakwa ezinyathelweni zokuzivikela ezinjengokugqoka amagilavu ​​nezingubo zokuzivikela.

-Gwema ukuhogela, ukuthinta isikhumba namehlo ngesikhathi sokusebenzisa.

-Uma ehogelwe ngephutha noma ethintwa ngephutha, umuntu othintekile kufanele aphuthunyiswe emoyeni omusha futhi elashwe ngosizo lwezempilo.

-Lapho ugcina, gcina i-2,4-difluorobenzylbromide kude nomlilo kanye ne-oxidant ukugwema ingozi yomlilo nokuqhuma.

  • Okwedlule:
  • Olandelayo:
    • Bhala umyalezo wakho lapha futhi usithumelele wona
