| Amakhodi Engozi | R45 – Ingabangela umdlavuza I-R22 – Iyingozi uma igwinywe R50/53 – Kunobuthi kakhulu ezintweni eziphila emanzini, kungabangela imiphumela emibi yesikhathi eside endaweni yasemanzini. R52/53 – Kuyingozi 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 R36/37/38 – Ukucasula amehlo, uhlelo lokuphefumula kanye nesikhumba. R20/21/22 – Kuyingozi ngokuhogela umoya, ukuthintana nesikhumba futhi uma ukugwinyile. R51/53 – Ukuba nobuthi ezintweni eziphila emanzini, kungabangela imiphumela emibi yesikhathi eside endaweni yasemanzini. R67 – Izihwamuko zingadala ukozela kanye nesiyezi |
| 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.) S60 – Le nto kanye nesiqukathi sayo kumele kulahlwe njengemfucuza eyingozi. I-S61 - Gwema ukudedelwa endaweni. Bheka imiyalelo ekhethekile / amaphepha edatha okuphepha. I-S36/37 – Gqoka izingubo zokuzivikela ezifanele namagilavu. S16 – Zigcine kude nemithombo yokuthungela. I-S7 – Gcina isitsha sivalwe ngokuqinile. S36 – Gqoka izingubo ezifanele zokuzivikela. S26 – Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha. |

Isingeniso
I-Benzidine (eyaziwa nangokuthi i-diphenylamine) iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso semvelo yayo, ukusetshenziswa, izindlela zokukhiqiza kanye nolwazi lokuphepha:
Ikhwalithi:
- Ukubukeka: I-Benzidine iyikristale eqinile emhlophe kuya kokuphuzi ngokukhanyayo.
- Ukuncibilika: akuncibiliki emanzini, kuncibilika kuzincibilikisi zemvelo ezifana notshwala, ama-ether, njll.
- Uphawu: Kuyi-electrophile enezimfanelo ze-electrophilic substitution reaction.
Sebenzisa:
- I-Benzidine isetshenziswa kabanzi emkhakheni we-organic synthesis. Ingasetshenziswa njengento eluhlaza kanye ne-synthetic intermediate yamakhemikhali afana nodayi, izingulube, amapulasitiki, njll.
Indlela:
- I-Benzidine ilungiselelwe ngokwesiko ngokuncishiswa kwe-dinitrobiphenyl, ukuqedwa kwemisebe ye-haloaniline, njll.
- Izindlela zesimanje zokulungiselela zihlanganisa ukwakheka kwezinto eziphilayo kwama-amine anephunga elimnandi, njengokusabela kwe-substrate diphenyl ether nama-amino alkanes.
Ulwazi Lokuphepha:
- I-Benzidine inobuthi futhi ingabangela ukucasuka nokulimala emzimbeni womuntu.
- Lapho uphatha i-benzidine, kufanele kuqashelwe ukugwema ukuthintana kwesikhumba nokuhogela, futhi izinto zokuzivikela ezifana namagilavu, izibuko zokuzivikela, namamaski okuzivikela kufanele kugqokwe uma kunesidingo.
- Uma i-benzidine ihlangana nesikhumba noma amehlo, kufanele ihlanjululwe ngokushesha ngamanzi amaningi.
- Lapho ugcina futhi usebenzisa i-benzidine, qaphela ukuthi ugwema ukuthintana nezinto eziphilayo kanye nama-oxidants ukuvimbela umlilo noma ukuqhuma.
