Gabatarwa

Benzidine (kuma aka sani da diphenylamine) wani fili ne na kwayoyin halitta. Mai zuwa shine gabatarwa ga yanayinsa, amfaninsa, hanyoyin masana'anta da bayanan aminci:

 

inganci:

- Bayyanar: Benzidine fari ne zuwa haske rawaya crystalline m.

- Solubility: wanda ba a iya narkewa a cikin ruwa, mai narkewa a cikin kaushi na kwayoyin halitta irin su alcohols, ethers, da dai sauransu.

- Alama: Electrophile ne wanda ke da kaddarorin abin maye gurbin electrophilic.

 

Amfani:

- Benzidine ana amfani da shi sosai a fagen haɗin gwiwar kwayoyin halitta. Ana iya amfani da shi azaman ɗanyen abu da tsaka-tsakin roba don sinadarai kamar rini, pigments, robobi, da sauransu.

 

Hanya:

- Benzidine an shirya shi ta al'ada ta hanyar rage dinitrobiphenyl, kawar da radiation na haloaniline, da dai sauransu.

- Hanyoyin shirye-shiryen zamani sun haɗa da haɗakar kwayoyin halitta na amines masu kamshi, irin su amsawar diphenyl ether na substrate tare da amino alkanes.

 

Bayanin Tsaro:

- Benzidine yana da guba kuma yana iya haifar da haushi da lalacewa ga jikin mutum.

- Lokacin da ake sarrafa benzidine, yakamata a kula don gujewa haɗuwa da fata da kuma shakar numfashi, sannan a sanya kayan kariya kamar safar hannu, gilashin kariya, da abin rufe fuska idan ya cancanta.

- Lokacin da benzidine ya hadu da fata ko idanu, to sai a wanke shi da ruwa mai yawa.

- Lokacin adanawa da amfani da benzidine, kula don guje wa hulɗa da kwayoyin halitta da abubuwan da ke haifar da oxidants don hana wuta ko fashewa.
