Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Amakhodi Engozi R45 – Ingabangela umdlavuza
R23/24/25 – Kunobuthi ngokuhogela, ukuthintana nesikhumba futhi uma ugwinywe.
R48/22 – Ingozi eyingozi yokulimala kabi empilweni ngokuchayeka isikhathi eside uma igwinywe.
R51/53 – Ukuba nobuthi ezintweni eziphila emanzini, kungabangela imiphumela emibi yesikhathi eside endaweni yasemanzini.
R62 – Ingozi engaba khona yokukhubazeka kokuzala
I-R68 – Ingozi engaba khona yemiphumela engenakuhlehliswa
R39/23/24/25 -
I-R11 – Ivutha Kakhulu
R52/53 – Kuyingozi ezintweni eziphila emanzini, kungabangela imiphumela emibi yesikhathi eside endaweni yasemanzini.
R36 – Ukucasuka emehlweni
R20/21/22 – Kuyingozi ngokuhogela umoya, ukuthintana nesikhumba futhi uma ukugwinyile.
R50/53 – Kunobuthi kakhulu ezintweni eziphila emanzini, kungabangela imiphumela emibi yesikhathi eside endaweni yasemanzini.
Incazelo Yokuphepha S53 – Gwema ukuchayeka – thola imiyalelo ekhethekile ngaphambi kokuyisebenzisa.
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.
I-S36/37 – Gqoka izingubo zokuzivikela ezifanele namagilavu.
S16 – Zigcine kude nemithombo yokuthungela.
S26 – Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha.
S60 – Le nto kanye nesiqukathi sayo kumele kulahlwe njengemfucuza eyingozi.

Isingeniso

I-2,4-Dinitrotoluene, eyaziwa nangokuthi i-DNMT, iyinhlanganisela yezinto eziphilayo.

 

Ikhwalithi:

- Ukubukeka: Amakristalu angenambala noma amakristalu ansundu ngokuphuzi.

- Kuqinile ekushiseni kwekamelo, kuncibilika kuzincibilikisi zemvelo ezifana ne-ethanol ne-methylene chloride, ezingancibiliki emanzini.

- Iqhuma kakhulu futhi inobuthi obuthile emzimbeni.

 

Sebenzisa:

- Njengempahla eluhlaza yeziqhumane zamasosha, njengokwenziwa kweziqhumane kanye ne-pyrotechnics.

- Isetshenziswa njenge-pigment intermediates, njengokwenza odayi nezinto ezithinta izithombe.

- Izicelo ku-organic synthesis reactions, njengokulungiswa kwama-reagents omthofu kwezinye izinhlanganisela.

 

Indlela:

I-2,4-I-Dinitrotoluene ivame ukulungiswa ngokusabela kwe-toluene nge-nitric acid. Izindlela ezijwayelekile zifaka indlela ye-nitric deboronic acid, indlela ye-nitrate ene-ferrous, kanye nendlela ye-asidi exubile. Kudingeka izinyathelo eziqinile zokuphepha ngesikhathi sokulungiselela.

 

Ulwazi Lokuphepha:

- 2,4-I-Dinitrotoluene iqhuma kakhulu futhi ingabangela imililo emibi nokuqhuma.

- Izinto zokuzivikela ezinjengamagilavu ​​okuzivikela, izibuko, nezingubo zokugqoka kufanele zigqokwe lapho uphathwa noma uphathwa.

- Gwema ukuhogela amagesi, intuthu, uthuli, nomhwamuko, futhi gwema ukuthintana nesikhumba namehlo.

- Gcina kude nomlilo nemithombo yokushisa ngesikhathi sokusebenzisa.
