Hordhac

Benzidine (sidoo kale loo yaqaan diphenylamine) waa iskudhis organic ah. Kuwa soo socdaa waa hordhac dabeecadeeda, isticmaalkeeda, hababka wax-soo-saarka iyo macluumaadka badbaadada:

 

Tayada:

- Muuqashada: Benzidine waa mid adag oo cad ama huruud ah.

- Solubility: oo aan lagu milmin biyaha, ku milma dareerayaasha organic sida khamriga, ethers, iwm.

- Astaanta: Waa koronto-dhal leh sifooyinka falcelinta beddelka elektrofiliga.

 

Isticmaal:

- Benzidine waxaa si weyn loogu isticmaalaa berrinkii synthesis organic. Waxa loo isticmaali karaa sidii alaab cayriin ah iyo dhex-dhexaadka synthetic ee kiimikooyinka sida dheeha, midabada, balaastikada, iwm.

 

Habka:

- Benzidine waxaa dhaqan ahaan loo diyaariyaa dinitrobiphenyl dhimista, baabi'inta shucaaca haloaniline, iwm.

- Hababka diyaarinta casriga ah waxaa ka mid ah isku dhafka organic ee amines caraf udgoon, sida falcelinta substrate diphenyl ether leh alkanes amino.

 

Macluumaadka Badbaadada:

- Benzidine waa sun waxayna u keeni kartaa xanaaq iyo dhaawac jidhka bini'aadamka.

- Marka la maaraynayo benzidine, waa in laga taxaddaraa si looga fogaado taabashada maqaarka iyo neefsashada, iyo qalabka ilaalinta sida galoofyada, muraayadaha difaaca, iyo maaskaro ilaalinta haddii loo baahdo.

- Marka benzidine ay taabato maqaarka ama indhaha, waa in isla markiiba lagu dhaqaa biyo badan.

- Markaad kaydinayso oo aad isticmaalayso benzidine, ka taxadar inaad iska ilaaliso xidhiidhka walxaha organic iyo oksidants si aad uga hortagto dab ama qarax.
