Ifaara

Benzidine (ti a tun mọ ni diphenylamine) jẹ agbo-ara Organic. Atẹle jẹ ifihan si iseda rẹ, lilo, awọn ọna iṣelọpọ ati alaye ailewu:

 

Didara:

- Irisi: Benzidine jẹ funfun si ina ofeefee kirisita ri to.

- Solubility: insoluble ninu omi, tiotuka ni Organic epo bi alcohols, ethers, ati be be lo.

- Aami: O jẹ elekitirofile ti o ni awọn ohun-ini ti iṣe iyipada elekitirofiki.

 

Lo:

Benzidine jẹ lilo pupọ ni aaye ti iṣelọpọ Organic. O le ṣee lo bi ohun elo aise ati agbedemeji sintetiki fun awọn kemikali gẹgẹbi awọn awọ, awọn awọ, awọn pilasitik, ati bẹbẹ lọ.
