Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Amakhodi Engozi R20/21 – Kuyingozi ngokuhogela umoya nangokuthinta isikhumba.
R25 – Kunobuthi uma ugwinywe
R43 - Ingabangela ukuzwela ngokuthinta isikhumba
R51/53 – Ukuba nobuthi ezintweni eziphila emanzini, kungabangela imiphumela emibi yesikhathi eside endaweni yasemanzini.
Incazelo Yokuphepha S24 – Gwema ukuthintana nesikhumba.
I-S37 – Gqoka amagilavu ​​afanelekile.
S45 – Uma kwenzeka ingozi noma uzizwa ungaphilile, funa iseluleko sezokwelapha ngokushesha (bonisa ilebula noma nini lapho kunokwenzeka.)
I-S61 - Gwema ukudedelwa endaweni. Bheka imiyalelo ekhethekile / amaphepha edatha okuphepha.

Isingeniso

I-2,5-Diaminotoluene iyinhlanganisela yezinto eziphilayo, okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-2,5-diaminotoluene:

 

Ikhwalithi:

- Ukubukeka: I-2,5-Diaminotoluene iyimpushana ecwebezelayo emhlophe kuya kokuphuzi.

- Ukunyibilika: Kuncibilika kancane emanzini, kodwa kuncibilika kakhulu kuzincibilikisi zemvelo njenge-benzene nezincibilikisi ezisekelwe etshwaleni.

 

Sebenzisa:

- 2,5-I-Diaminotoluene iyingxenye ebalulekile ye-organic synthesis, evame ukusetshenziswa ekulungiseleleni ama-pigments namadayi, ikakhulukazi ekulungiseleleni izinto zekhwalithi ye-fiber zokwenziwa.

 

Indlela:

- Ukulungiswa kwe-2,5-diaminotoluene kufezwa ngokuyinhloko ngokunciphisa i-nitrotoluene. I-nitrotoluene iqala ukuhlangana ne-ammonia ukukhiqiza i-2,5-dinitrotoluene, ebese yehliswa ibe yi-2,5-diaminotoluene nge-ejenti yokunciphisa efana ne-sodium diene.

 

Ulwazi Lokuphepha:

- I-2,5-Diaminotoluene iyacasula emehlweni nasesikhumbeni, ngakho gqoka izinto zokuzivikela ezifanele futhi ugweme ukuthintana lapho uzisebenzisa.

- Lapho usebenza, gwema ukuhogela uthuli noma isixazululo salo futhi ugcine izimo ezinhle zokungenisa umoya.

- 2,5-I-Diaminotoluene kufanele igcinwe kude nezinto ezivuthayo kanye ne-oxidizing, futhi igcinwe endaweni eyomile, epholile.

- Landela izinqubo ezifanele zokusebenza eziphephile futhi ulahle imfucuza ngendlela efanele lapho uphatha noma ugcina.
