Hoʻolauna
ʻO Benzidine (ʻike pū ʻia ʻo diphenylamine) he mea hoʻohuihui. ʻO kēia ka hoʻolauna ʻana i kona ʻano, hoʻohana, hana hana a me ka ʻike palekana:
ʻAno maikaʻi:
- Ke ʻano: ʻO Benzidine he keʻokeʻo a me ka māmā melemele crystalline paʻa.
- Solubility: hiki ʻole ke hoʻoheheʻe ʻia i loko o ka wai, hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe organik e like me nā alcohols, ethers, etc.
- Hōʻailona: He electrophile i loaʻa nā waiwai o kahi pane hoʻololi electrophilic.
E hoʻohana:
- Hoʻohana nui ʻia ʻo Benzidine i ke kahua o ka synthesis organik. Hiki ke hoʻohana ʻia ma ke ʻano he mea maka a me ka synthetic intermediate no nā kemika e like me nā dyes, pigments, plastics, etc.
Hanana:
- Hoʻomākaukau ʻia ʻo Benzidine e ka dinitrobiphenyl reduction, radiation elimination o haloaniline, etc.
- ʻO nā ʻano hana hoʻomākaukau o kēia wā e pili ana i ka synthesis organik o nā amine aromatic, e like me ka hopena o ka substrate diphenyl ether me nā amino alkanes.
ʻIke palekana:
- He mea ʻawaʻawa ʻo Benzidine a hiki ke hōʻeha i ke kino o ke kanaka.
- I ka lawelawe ʻana i ka benzidine, pono e mālama ʻia e pale aku i ka pili ʻana o ka ʻili a me ka inhalation, a pono e hoʻohana ʻia nā mea pale e like me nā mīkina lima, nā aniani pale, a me nā maka pale inā pono.
- Ke komo ka benzidine i ka ʻili a i ʻole nā maka, pono e holoi koke ʻia me ka wai nui.
- I ka mālama ʻana a me ka hoʻohana ʻana i ka benzidine, e makaʻala e pale aku i ka hoʻopili ʻana me nā mea olaola a me nā mea ʻona e pale ai i ke ahi a i ʻole pahū.
