R52/53 – Iyingozi kwizinto eziphila emanzini, inokubangela iziphumo ezibi zexesha elide kwindawo ehlala emanzini. R39/23/24/25 - I-R23/24/25 – Ityhefu ngokuphefumla, xa udibana nesikhumba naxa uginyiwe. I-R11 – Iyatsha kakhulu R36/37/38 – Ukucaphuka kwamehlo, inkqubo yokuphefumla kunye nolusu. I-R20/21/22 – Iyingozi ngokuphefumla, xa udibana nolusu naxa uginyiwe. R51/53 – Ityhefu kwizinto eziphila emanzini, inokubangela iziphumo ezibi zexesha elide kwindawo ehlala emanzini. R67 – Umphunga unokubangela ukozela kunye nesiyezi |
| Inkcazelo yoKhuseleko | S53 – Kuphephe ukuba sesichengeni – fumana imiyalelo eyodwa phambi kokusetyenziswa. S45 - Kwimeko yengozi okanye ukuba uziva ungaphilanga, funa iingcebiso zonyango ngokukhawuleza (bonisa ileyibhile nanini na kunokwenzeka.) S60 – Esi sixhobo kunye nesingxobo saso kufuneka silahlwe njengenkunkuma eyingozi. S61 –Kuphephe ukukhutshelwa kokusingqongileyo. Jonga kwimiyalelo ekhethekileyo / kumaphepha edatha yokhuseleko. S36/37 – Nxiba iimpahla ezifanelekileyo zokukhusela kunye neeglavu. S16 – Gcina kude kwimithombo yomlilo. S7 – Gcina isikhongozeli sivalwe ngokuqinileyo. S36 – Nxiba iimpahla ezifanelekileyo ezikhuselayo. S26 – Xa udibana namehlo, hlambulula ngokukhawuleza ngamanzi amaninzi kwaye ufune iingcebiso zonyango. |

Intshayelelo
I-Benzidine (eyaziwa ngokuba yi-diphenylamine) yi-organic compound. Oku kulandelayo sintshayelelo kubume bayo, ukusetyenziswa, iindlela zokwenza kunye nolwazi lokhuseleko:
Umgangatho:
- Imbonakalo: I-Benzidine yikristale emhlophe ukuya kokukhanya etyheli.
-Ukunyibilika: akunyibiliki emanzini, kunyibilika kwizinyibilikisi zendalo ezifana neealkoholi, ii-ethers, njl.
- Uphawu: I-electrophile eneempawu ze-electrophilic substitution reaction.
Sebenzisa:
- I-Benzidine isetyenziswa ngokubanzi kwintsimi ye-organic synthesis. Ingasetyenziswa njengento eluhlaza kunye ne-synthetic intermediate kwiikhemikhali ezinje ngedayi, ii-pigments, iiplastiki, njl.
Indlela:
- I-Benzidine ilungiselelwe ngokwesiko ngokunciphisa i-dinitrobiphenyl, ukupheliswa kwemisebe ye-haloaniline, njl.
- Iindlela zokulungiselela zale mihla zibandakanya ukuhlanganiswa kwe-organic yee-amines ezinuka kamnandi, njengokusabela kwe-substrate diphenyl ether kunye ne-amino alkanes.
Ulwazi ngoKhuseleko:
- I-Benzidine inetyhefu kwaye inokubangela ukucaphuka kunye nomonakalo kumzimba womntu.
- Xa uphethe i-benzidine, kufuneka kuthathelwe ingqalelo ukuphepha ukudibanisa kwesikhumba kunye nokuphefumla, kunye nezixhobo zokukhusela ezifana neeglavu, iiglasi zokukhusela, kunye neemaski zokukhusela kufuneka zigqitywe xa kuyimfuneko.
- Xa i-benzidine idibana nolusu okanye amehlo, kufuneka ihlanjwe ngokukhawuleza ngamanzi amaninzi.
-Xa ugcina kwaye usebenzisa i-benzidine, lumkela ukuthintela ukudibana nezinto eziphilayo kunye nee-oxidants ukuthintela umlilo okanye ugqabhuko-dubulo.
