ʻAno a me nā waiwai kumu o ka p-toluidine
ʻAno: he kristal ʻōniʻoniʻo ʻole ka p-toluidine, a he kristal paʻa keʻokeʻo a melemele māmā paha, a hiki ke ʻike ʻia hoʻi i ke ʻano ʻeleʻele a ʻeleʻele.
Ka hoʻoheheʻe ʻia: Hoʻoheheʻe iki ʻia i ka wai, akā hoʻoheheʻe ʻia i loko o nā ʻano mea hoʻoheheʻe like ʻole e like me ka ethanol, ether, benzene, a me ka waikawa hydrochloric.
Nā waiwai kino ʻē aʻe: Kiko heheʻe: ʻO ka maʻamau ma waena o 41-46°C 23. Kiko paila: 200°C (kaomi maʻamau). Density: ʻO ka density pili ma kahi o 0.9619 a i 0.973 g/mL (ma 25°C). Refractive index: Ma kahi o 1.5534 a i 1.5636 34. Flash point: Ma kahi o 86°C a i ʻole 192°F. Hoʻohana nui ʻia ʻo p-Toluidine ma ke ʻano he dye intermediate a me kahi intermediate o ka pyrimethamine lāʻau lapaʻau i ka ʻoihana, akā pono e hoʻomaopopo ʻia he mea ʻawahia a he mea hana methemoglobin ikaika, no laila pono e hoʻohana ʻia me ke akahele.
I ka hōʻuluʻulu manaʻo, he nui nā ʻano o ka p-toluidine, a ʻokoʻa kona mau waiwai kino ma muli o ke ʻano a me nā kūlana.
Nā hoʻohana ʻana o ka p-toluidine
ʻO ka mea hana loiloi: hoʻohana ʻia ka p-toluidine ma ke ʻano he mea hana i loko o ke kemika loiloi e kōkua i ka hana ʻana i nā loiloi kemika kikoʻī. Hana ʻana o ka dye: He waena ia no nā dyes he nui, e like me ke kumu ʻulaʻula GL, methylamine red lake, basic fuchsin, a hoʻohana nui ʻia i ka hana dye i loko o ka lole, ka paʻi ʻana a me nā ʻoihana ʻē aʻe. Hana ʻana o ka lāʻau lapaʻau: Ma ke kahua lāʻau lapaʻau, ʻo ka p-toluidine kahi waena no ka lāʻau pyrimethamine, he mea nui ia no ka hana ʻana o nā lāʻau lapaʻau. Nā noi ʻē aʻe: hiki ke hoʻohana ʻia ka p-toluidine e hoʻomākaukau i ka 1-hydroxy-4-(p-toluidine)-anthraquinone, kahi i hoʻohana ʻia ma ke ʻano he mea hana koʻikoʻi no ka hoʻoholo ʻana i ka boron a hoʻohana nui ʻia no ke kala ʻana o ka pulp fiber polyester.
ʻO p-Toluidine, i ʻike ʻia hoʻi ʻo 4-toluidine, he hui organik me ke ʻano kemika o C7H9N. He kristal ʻālohilohi, ʻaʻohe kala, hoʻoheheʻe iki ʻia i ka wai, akā hoʻoheheʻe ʻia i ka ethanol, ether, benzene, a me ka waikawa hydrochloric. Pono e hoʻomaopopo ʻia he mea ʻawahia ka p-Toluidine, he mea hana methemoglobin ikaika, a hiki ke hoʻonāukiuki i ka ʻōpū mimi a me ka urethra a hoʻoulu i ka hematuria, no laila e hoʻohana pono ʻia me ke akahele.
