Ifomu kanye nezakhiwo eziyisisekelo ze-p-toluidine
Uhlobo: i-p-toluidine iyikristalu engenambala, ecwebezelayo, noma i-solid emhlophe kuya kophuzi okhanyayo, futhi ingavela futhi ngesimo esinsundu kuya konsundu.
Ukuncibilika: Kuncibilika kancane emanzini, kodwa kuncibilika ezincibilikisini ezahlukahlukene ezifana ne-ethanol, i-ether, i-benzene, kanye ne-hydrochloric acid.
Ezinye izakhiwo zomzimba: Iphuzu lokuncibilika: Ngokuvamile phakathi kuka-41-46°C 23. Iphuzu lokubila: 200°C (ingcindezi evamile). Ubuningi: Ubuningi obuhlobene bungaba ngu-0.9619 kuya ku-0.973 g/mL (ku-25°C). Inkomba yokuzivuselela: Cishe ngu-1.5534 kuya ku-1.5636 34. Iphuzu lokusha: Cishe ngu-86°C noma 192°F. I-p-Toluidine isetshenziswa kakhulu njenge-dye intermediate kanye ne-intermediate ye-pyrimethamine yemithi embonini, kodwa kufanele kuqashelwe ukuthi inobuthi futhi iyi-methemoglobin enamandla, ngakho-ke kufanele isetshenziswe ngokuqapha.
Ngamafuphi, i-p-toluidine inezinhlobo eziningi, futhi izakhiwo zayo zomzimba ziyahlukahluka kuye ngesimo kanye nezimo.
Ukusetshenziswa kwe-p-toluidine
I-reagent yokuhlaziya: i-p-toluidine isetshenziswa njenge-reagent kumakhemikhali okuhlaziya ukusiza ukwenza ukuhlaziywa kwamakhemikhali athile. Ukwenziwa kwedayi: Kuyindlela ephakathi kwamadayi amaningi, njenge-red base GL, i-methylamine red lake, i-basic fuchsin, futhi isetshenziswa kabanzi ekuhlanganisweni kwedayi ezindwangu, ekunyatheliseni nakwezinye izimboni. Indlela ephakathi kwemithi: Emkhakheni wemithi, i-p-toluidine iyindlela ephakathi kwe-pyrimethamine yesidakamizwa, ebalulekile ekuhlanganisweni kwemithi. Ezinye izinhlelo zokusebenza: i-p-toluidine ingasetshenziswa futhi ukulungiselela i-1-hydroxy-4-(p-toluidine)-anthraquinone, esetshenziswa njenge-reagent ebucayi yokunquma i-boron futhi isetshenziswa kakhulu ekufakeni umbala kwe-pulp ye-polyester fiber.
I-p-Toluidine, eyaziwa nangokuthi i-4-toluidine, iyinhlanganisela yezinto eziphilayo enefomula yamakhemikhali ye-C7H9N. Iyikristalu engenambala, ecwebezelayo, encibilikayo kancane emanzini, kodwa incibilika ku-ethanol, i-ether, i-benzene, kanye ne-hydrochloric acid. Kufanele kuqashelwe ukuthi i-p-Toluidine inobuthi, i-methemoglobin enamandla, futhi ingacasula isinyi kanye ne-urethra futhi ibangele i-hematuria, ngakho-ke kufanele isetshenziswe ngokuqapha.
