Chimiro uye hunhu hwepakutanga hwe p-toluidine

Chimiro: p-toluidine ikristaro isina ruvara, inopenya ine maburi, kana kuti chena kusvika yero yakajeka, uye inogonawo kuoneka muchimiro chebrown kusvika kubrown.
Kunyungudika: Inonyungudika zvishoma mumvura, asi inonyungudika muzvinhu zvakasiyana-siyana zvakaita se ethanol, ether, benzene, uye hydrochloric acid.
Zvimwe zvinhu zvepanyama: Nzvimbo yekunyunguduka: Kazhinji pakati pe41-46°C 23. Nzvimbo yekufashaira: 200°C (kumanikidzwa kwakajairika). Kuwanda: Kuwanda kwechinhu kunenge kuri pakati pe0.9619 kusvika 0.973 g/mL (pa25°C). Refractive index: Inenge 1.5534 kusvika 1.5636 34. Flash point: Inenge 86°C kana 192°F. p-Toluidine inonyanya kushandiswa sedhayi repakati uye chikamu chepakati che pyrimethamine yemishonga muindasitiri, asi zvinofanira kucherechedzwa kuti ine chepfu uye ine methemoglobin yakasimba, saka inofanira kushandiswa nekungwarira.
Muchidimbu, p-toluidine ine mhando dzakasiyana-siyana, uye hunhu hwayo hunosiyana zvichienderana nechimiro nemamiriro ezvinhu.
Mashandisirwo e p-toluidine
Chinogadzirisa makemikari: p-toluidine inoshandiswa sechinogadzirisa makemikari mukuongorora makemikari kuti ibatsire kuita ongororo chaiyo yemakemikari. Kugadzira dhayi: Inoshandiswa pakati pemadhayi akawanda, akadai se red base GL, methylamine red lake, basic fuchsin, uye inoshandiswa zvakanyanya mukugadzira dhayi mumachira, kudhinda nemamwe maindasitiri. Chinogadzirisa makemikari: Muchikamu chemishonga, p-toluidine inyanzvi yemishonga inonzi pyrimethamine, iyo inokosha pakugadzira mishonga. Mamwe mashandisirwo: p-toluidine inogonawo kushandiswa kugadzira 1-hydroxy-4-(p-toluidine)-anthraquinone, iyo inoshandiswa sechinogadzirisa makemikari kuti ione boron uye inonyanya kushandiswa pakupenda polyester fiber pulp.
p-Toluidine, inozivikanwawo se4-toluidine, imusanganiswa wemakemikari une fomura yemakemikari yeC7H9N. Ikristaro isina ruvara, inopenya, inonyunguduka zvishoma mumvura, asi inonyunguduka muethanol, ether, benzene, uye hydrochloric acid. Zvinofanira kucherechedzwa kuti p-Toluidine ine chepfu, ine methemoglobin yakasimba, uye inogona kutsamwisa dundira neurethra uye kukonzera hematuria, saka inofanira kushandiswa nekungwarira.
