Sebopeho le thepa ea motheo ea p-toluidine

Sebopeho: p-toluidine ke kristale e se nang 'mala, e benyang e nang le matheba, kapa e tšoeu ho isa bosehla bo bobebe, 'me e ka boela ea hlaha ka mokhoa o sootho ho isa ho o sootho.
Ho qhibiliha: E qhibiliha hanyane ka metsing, empa e qhibiliha ka har'a mefuta e fapaneng ea li-solvents tse kang ethanol, ether, benzene le hydrochloric acid.
Litšobotsi tse ling tsa 'mele: Sebaka sa ho qhibiliha: Hangata pakeng tsa 41-46°C 23. Sebaka sa ho belisa: 200°C (khatello e tloaelehileng). Botenya: Botenya bo amanang bo ka ba 0.9619 ho isa ho 0.973 g/mL (ho 25°C). Index ea refractive: Hoo e ka bang 1.5534 ho isa ho 1.5636 34. Sebaka sa ho fifala: Hoo e ka bang 86°C kapa 192°F. p-Toluidine e sebelisoa haholo e le sebaka sa ho daea le sebaka sa ho fifala sa pyrimethamine ea meriana indastering, empa ho lokela ho hlokomeloa hore e chefo 'me ke methemoglobin e matla, kahoo e lokela ho sebelisoa ka hloko.
Ka bokhutšoanyane, p-toluidine e na le mefuta e mengata, 'me thepa ea eona ea' mele e fapana ho latela sebopeho le maemo.
Tšebeliso ea p-toluidine
Setlolo sa tlhahlobo: p-toluidine e sebediswa e le setlolo sa tlhahlobo k'hemistring ho thusa ho etsa ditlhahlobo tse ikgethang tsa dikhemikhale. Ho kopanya dae: Ke setlolo sa didae tse ngata, tse kang GL e kgubedu, methylamine red lake, basic fuchsin, mme e sebediswa haholo ho kopanyeng dae diindastering tsa masela, kgatiso le tse ding. Setlolo sa meriana: Lefapheng la meriana, p-toluidine ke setlolo sa meriana sa pyrimethamine, e leng sa bohlokwa bakeng sa ho kopanya dithethefatsi. Ditshebediso tse ding: p-toluidine e ka boela ya sebediswa ho lokisa 1-hydroxy-4-(p-toluidine)-anthraquinone, e sebediswang e le setlolo se utlwahalang bakeng sa ho fumana boron mme e sebediswa haholo bakeng sa ho daya pulp ya polyester fiber.
p-Toluidine, e tsejoang hape e le 4-toluidine, ke motsoako oa tlhaho o nang le foromo ea lik'hemik'hale ea C7H9N. Ke kristale e se nang 'mala, e benyang e nang le matheba, e qhibilihang hanyane ka metsing, empa e qhibiliha ka har'a ethanol, ether, benzene le hydrochloric acid. Ho lokela ho hlokomeloa hore p-Toluidine e na le chefo, ke methemoglobin e matla, 'me e ka halefisa senya le urethra le ho baka hematuria, kahoo e lokela ho sebelisoa ka hloko.
