Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Amakhodi Engozi R20 – Kuyingozi ngokuhogela umoya
R51/53 – Ukuba nobuthi ezintweni eziphila emanzini, kungabangela imiphumela emibi yesikhathi eside endaweni yasemanzini.
R39/23/24/25 -
R23/24/25 – Kunobuthi ngokuhogela, ukuthintana nesikhumba futhi uma ugwinywe.
I-R11 – Ivutha Kakhulu
U-R10 – Uyavutha
R43 - Ingabangela ukuzwela ngokuthinta isikhumba
Incazelo Yokuphepha I-S24/25 - Gwema ukuthintana nesikhumba namehlo.
I-S61 - Gwema ukudedelwa endaweni. Bheka imiyalelo ekhethekile / amaphepha edatha okuphepha.
S45 – Uma kwenzeka ingozi noma uzizwa ungaphilile, funa iseluleko sezokwelapha ngokushesha (bonisa ilebula noma nini lapho kunokwenzeka.)

Isingeniso

I-4-Chlorotoluene iyinhlanganisela yezinto eziphilayo. Iwuketshezi olungenambala olunambitheka obumnandi obukhethekile. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-4-chlorotoluene:

 

Ikhwalithi:

- Ukubukeka: Uketshezi olungenambala

- Ukuminyana okuhlobene: 1.10 g/cm³

- Ukuncibilika: akuncibiliki emanzini, kuncibilika kuzincibilikisi eziphilayo njenge-ether, i-ethanol, njll.

 

Sebenzisa:

- I-4-chlorotoluene isetshenziswa ngokuyinhloko njengendawo emaphakathi ku-organic synthesis futhi ibamba iqhaza ekuphenduleni kwamakhemikhali okuningi njengokusabela kokushintsha, ukusabela kwe-oxidation, njll.

- Ibuye isetshenziswe njengesithako ezinngolweni ukunikeza imikhiqizo iphunga elisha.

 

Indlela:

- 4-Chlorotoluene ngokuvamile itholakala ngokusabela toluene nge chlorine gas. Ukusabela ngokuvamile kwenziwa ngaphansi kwesenzo sokukhanya kwe-ultraviolet noma ama-catalysts.

 

Ulwazi Lokuphepha:

I-4-Chlorotoluene inobuthi futhi ingadala umonakalo kubantu ngokumuncwa kwesikhumba nemizila yokuhogela.

- Gwema ukuthintana ngqo nesikhumba nge-4-chlorotoluene futhi ugqoke izinto zokuzivikela ezifana namagilavu ​​okuzivikela, izibuko, nezingubo.

- Gcina indawo enomoya omuhle ngesikhathi sokusebenza futhi ugweme ukuhogela amagesi ayingozi.

- Ukuchayeka ekugxilweni okuphezulu kwe-4-chlorotoluene kungase kubangele ukungaphatheki kahle kwamehlo nokuphefumula, futhi kubangele ukuminyanisa noma ukusabela koshevu. Uma unezimpawu ezingakhululekile, kufanele uyeke ukuyisebenzisa ngokushesha futhi uxhumane nodokotela ukuze uthole ukwelashwa.
