Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Amakhodi Engozi I-R22 – Iyingozi uma igwinywe
R36/37/38 – Ukucasula amehlo, uhlelo lokuphefumula kanye nesikhumba.
Incazelo Yokuphepha S22 - Ungaphefumuli uthuli.
I-S24/25 - Gwema ukuthintana nesikhumba namehlo.
S37 – Gqoka amagilavu ​​afanelekile.
S26 – Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha.
Ikhodi ye-HS 29163990
I-Hazard Class I-IRRITANT

 

Isingeniso

I-2-Chloro-5-fluorobenzoic acid iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sobunjalo bayo, ukusetshenziswa, indlela yokulungiselela kanye nolwazi lokuphepha:

 

Ikhwalithi:

- Ukubukeka: Angenambala kuya kokukhanya amakristalu aphuzi noma izimpushana eziyikristale.

- Ukunyibilika: kuncibilika kuzincibilikisi zemvelo, kuncibilika kancane emanzini.

 

Sebenzisa:

- I-2-Chloro-5-fluorobenzoic acid ivame ukusetshenziswa njengendawo ephakathi ku-organic synthesis.

- Ingasetshenziswa futhi njenge-organic synthesis reagent kanye ne-catalyst.

 

Indlela:

I-2-Chloro-5-fluorobenzoic acid ivamise ukulungiselelwa yilokhu:

I-2-chloro-5-fluorobenzyl utshwala iphendulwa nge-sodium hydroxide (NaOH) noma i-potassium hydroxide (KOH) ukuze kutholwe usawoti wesodium ohambisanayo noma usawoti we-potassium.

I-acidified nge-hydrochloric acid ukukhiqiza i-2-chloro-5-fluorobenzoic acid.

 

Ulwazi Lokuphepha:

- I-2-Chloro-5-fluorobenzoic acid iyinto evuthayo futhi kufanele igwenywe ukuthintana nama-oxidizing aqinile noma umoya-mpilo.

- Gqoka izinto zokuzivikela ezifanele, njengamagilavu, izibuko, nezingubo zokuzivikela, lapho uphatha noma uphethe.

- Gwema ukuhogela uthuli noma isixazululo sayo futhi usebenze endaweni engenawo umoya.

- Gcina kude namazinga okushisa aphezulu, umlilo, kanye nelanga eliqondile, futhi ugcine isitsha sivalwe ngokuqinile.

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