Omaka bomkhiqizo

Amakhodi Engozi R36/37/38 – Ukucasula amehlo, uhlelo lokuphefumula kanye nesikhumba.
R34 – Ibangela ukusha
Incazelo Yokuphepha S26 – Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha.
I-S37/39 – Gqoka amagilavu ​​afanelekile kanye nokuvikela iso/ubuso
S36/39 -
S45 – Uma kwenzeka ingozi noma uzizwa ungaphilile, funa iseluleko sezokwelapha ngokushesha (bonisa ilebula noma nini lapho kunokwenzeka.)
S36/37/39 – Gqoka izingubo zokuzivikela ezifanele, amagilavu ​​kanye nokuvikela iso/ubuso.

Isingeniso

I-3-Bromo-4-chlorotrifluorotoluene iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso semvelo yayo, ukusetshenziswa, indlela yokukhiqiza kanye nolwazi lokuphepha:

 

Ikhwalithi:

- Ukubukeka: Uketshezi olungenambala

- Ukunyibilika: Kuncibilika kancane emanzini, kuncibilika kuzincibilikisi zemvelo ezifana ne-ether ne-benzene

 

Sebenzisa:

I-3-Bromo-4-chlorotrifluorotoluene inezinhlobonhlobo zokusetshenziswa ku-organic synthesis. Iphinde ibe nokusetshenziswa okuthile kwezolimo, njengokuhlanganiswa kwezibulala-zinambuzane nezibulala ukhula.

 

Indlela:

Izindlela zokulungiselela ze-3-bromo-4-chlorotrifluorotoluene ikakhulukazi zimi kanje:

I-4-chloro-3-fluorotoluene ilungiswa kuqala bese isabela nge-bromine ukwenza umkhiqizo oqondiwe.

Umkhiqizo okuhlosiwe ulungiswa ngokuphendula i-chlorofluorotoluene ne-bromine ku-dichloromethane noma i-dichloromethane phambi kwe-ferric bromide.

 

Ulwazi Lokuphepha:

- Gwema ukuthinta isikhumba, amehlo, kanye nomgudu wokuphefumula. Uma kwenzeka ukuthintana, hlambulula ngokushesha ngamanzi amaningi.

- Gqoka amagilavu ​​okuzivikela, izibuko nezingubo lapho usebenza.

- Gwema ukuhogela inkungu noma inkungu futhi ugcine indawo yokusebenza enomoya omuhle.

- Gcina kude nomlilo nama-oxidants aqinile.

- Sicela ufunde futhi ulandele izinqubo zokusebenza zokuphepha ezifanele ngesikhathi sokusetshenziswa.

 

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