p-Phenylene diamine1,4-diaminobenzene

He aniani keʻokeʻo. Huli i ka ʻulaʻula i ka mālamalama. Huli i ka poni i ka lewa. Hehi hoʻoheheʻe 140℃. Hehi paila 267℃. Hiki ke hoʻohaʻahaʻa ʻia. Hoʻoheheʻe iki ʻia i ka wai anuanu, hoʻoheheʻe ʻia i ka ethanol, ether, chloroform a me benzene. Hoʻopili ia me nā waikawa inorganic e hana i nā paʻakai e maʻalahi ke hoʻoheheʻe ʻia i ka wai. Hoʻohana ʻia i ka hana ʻana i nā dyes azo a me nā dyes sulfur, a pēlā aku, a hoʻohana ʻia e like me nā dyes huluhulu (Fur Black D, Ursol D a i ʻole Fur Black D, Ursol D a i ʻole Fur Black D) a me nā mea hoʻomohala. No kēia huahana nā carcinogens Māhele 3. Hana ʻia ia ma ka hōʻemi ʻana o ka p-nitroaniline.

ʻO ke ʻano hana

Loaʻa ia ma ka hoʻemi ʻana i ka p-nitroaniline me ka pauka hao i loko o ka ʻawaʻawa. E hoʻokomo i ka pauka hao i loko o ka waikawa hydrochloric, e hoʻomehana iā ia i 90°C, a hoʻohui i ka p-nitroaniline me ka hoʻoulu ʻana. Ma hope o ka pau ʻana o ka hoʻohui ʻana, e hana ma 95-100°C no 0.5 mau hola, a laila e hoʻohui i ka waikawa hydrochloric i hoʻopaʻa ʻia i kulu liʻiliʻi e hoʻopau i ka hopena hoʻemi Chemicalbook. Ma hope o ka hoʻomaʻalili ʻana, e hoʻopau me ka hopena sodium carbonate saturated i ka pH 7-8, e hoʻolapalapa a kānana i ka wā wela, a holoi i ka keke kānana me ka wai wela. E hoʻohui i ka filtrate a me ka wai holoi, e hoʻopaʻa ma lalo o ke kaomi i hoʻemi ʻia, e crystallize ma ka hoʻomaʻalili ʻana a i ʻole e distill ma lalo o ke kaomi i hoʻemi ʻia e loaʻa ai ka p-phenylenediamine me ka hua o 95%.
