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.
