Mawonekedwe ndi makhalidwe oyambira a p-toluidine
Kapangidwe kake: p-toluidine ndi kristalo yopanda mtundu, yowala, kapena yoyera mpaka yachikasu yopepuka, ndipo imatha kuonekanso mu mtundu wa utoto mpaka bulauni.
Kusungunuka: Kusungunuka pang'ono m'madzi, koma kumasungunuka m'mitundu yosiyanasiyana ya zinthu monga ethanol, ether, benzene, ndi hydrochloric acid.
Zinthu zina zakuthupi: Malo osungunuka: Nthawi zambiri pakati pa 41-46°C 23. Malo otentha: 200°C (kupanikizika kwabwinobwino). Kuchulukana: Kuchulukana kwapafupifupi ndi pafupifupi 0.9619 mpaka 0.973 g/mL (pa 25°C). Chizindikiro cha Refractive: Pafupifupi 1.5534 mpaka 1.5636 34. Malo owunikira: Pafupifupi 86°C kapena 192°F. p-Toluidine imagwiritsidwa ntchito kwambiri ngati chopaka utoto komanso chopaka utoto cha pyrimethamine yamankhwala m'makampani, koma ziyenera kudziwika kuti ndi poizoni ndipo ndi methemoglobin wamphamvu, choncho iyenera kugwiritsidwa ntchito mosamala.
Mwachidule, p-toluidine ili ndi mitundu yosiyanasiyana, ndipo mawonekedwe ake amasiyana malinga ndi mawonekedwe ndi mikhalidwe.
Kugwiritsa ntchito p-toluidine
Chothandizira kusanthula: p-toluidine imagwiritsidwa ntchito ngati chothandizira mu chemistry yowunikira kuti ithandize kuchita kusanthula kwapadera kwa mankhwala. Kupanga utoto: Ndi chinthu chapakati cha utoto wambiri, monga red base GL, methylamine red lake, basic fuchsin, ndipo chimagwiritsidwa ntchito kwambiri popanga utoto m'mafakitale a nsalu, kusindikiza ndi mafakitale ena. Chothandizira pa zamankhwala: Mu gawo la mankhwala, p-toluidine ndi chinthu chapakati cha pyrimethamine ya mankhwala, yomwe ndi yofunika kwambiri popanga mankhwala. Ntchito zina: p-toluidine ingagwiritsidwenso ntchito kukonzekera 1-hydroxy-4-(p-toluidine)-anthraquinone, yomwe imagwiritsidwa ntchito ngati chothandizira kudziwa boron ndipo imagwiritsidwa ntchito kwambiri popanga utoto wa polyester fiber pulp.
P-Toluidine, yomwe imadziwikanso kuti 4-toluidine, ndi mankhwala achilengedwe okhala ndi formula ya C7H9N. Ndi kristalo wopanda mtundu, wonyezimira wosalala, wosungunuka pang'ono m'madzi, koma wosungunuka mu ethanol, ether, benzene, ndi hydrochloric acid. Dziwani kuti p-Toluidine ndi poizoni, methemoglobin wamphamvu, ndipo imatha kukwiyitsa chikhodzodzo ndi urethra ndikuyambitsa hematuria, kotero iyenera kugwiritsidwa ntchito mosamala.
