Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Amakhodi Engozi R36/37/38 – Ukucasula amehlo, uhlelo lokuphefumula kanye nesikhumba.
R59 – Iyingozi kungqimba lwe-ozone
Incazelo Yokuphepha I-S37/39 – Gqoka amagilavu ​​afanelekile kanye nokuvikela iso/ubuso
S26 – Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha.
I-S59 – Bheka kumkhiqizi / umphakeli ukuze uthole ulwazi mayelana nokuthola kabusha / ukugaywa kabusha.
Ama-ID e-UN 1941
I-WGK Germany 3
I-RTECS PA7525000
Ikhodi ye-HS 29034700
Inothi Lengozi Iyacasula
I-Hazard Class 9
Iqembu Lokupakisha III
Ubuthi Ukuchayeka kwemizuzu eyi-15 ku-6,400 kanye ne-8,000 ppm kwabulala amagundane namagundane, ngokulandelana (Patnaik,
1992).

 

Isingeniso

I-Dibromodifluoromethane (CBr2F2), eyaziwa nangokuthi i-halothane (i-halothane, i-trifluoromethyl bromide), iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-dibromodifluoromethane:

 

Ikhwalithi:

- Ukubukeka: Uketshezi olungenambala

- I-Solubility: i-soluble ku-ethanol, i-ether ne-chloride, inyibilika kancane emanzini

- Ubuthi: bunomphumela wokubulala izinzwa futhi kungaholela ekucindezelekeni kwesimiso sezinzwa esimaphakathi

 

Sebenzisa:

- Imithi yokubulala izinzwa: I-Dibromodifluoromethane, eyake yasetshenziswa kakhulu emithanjeni nasekwenzeni izinzwa ezivamile, manje isithathelwe indawo yimithi yokubulala izinzwa ethuthuke kakhulu futhi ephephile.

 

Indlela:

Ukulungiswa kwe-dibromodimomethane kungenziwa ngezinyathelo ezilandelayo:

I-Bromine isabela ne-fluorine emazingeni okushisa aphezulu ukuze inikeze i-fluorobromide.

I-Fluorobromide isabela nge-methane ngaphansi kwemisebe ye-ultraviolet ukuze ikhiqize i-dibromodifluoromethane.

 

Ulwazi Lokuphepha:

- I-Dibromodifluoromethane inezici zokubulala izinzwa futhi kufanele isetshenziswe ngokuqapha, ikakhulukazi ngaphandle kokuqondisa kochwepheshe.

- Ukuchayeka isikhathi eside ku-dibromodifluoromethane kungase kube nemiphumela emibi esibindini.

- Ingabangela ukucasuka uma ingena emehlweni, esikhunjeni, noma ohlelweni lokuphefumula.

- Uma usebenzisa i-dibromodifluoromethane, ilangabi noma izinga lokushisa eliphezulu kufanele ligwenywe njengoba livutha.

- Uma usebenzisa i-dibromodifluoromethane, landela izinqubo ezifanele zaselabhorethri kanye nezinyathelo zokuzivikela.
