Ifom kunye neempawu ezisisiseko ze-p-toluidine

Uhlobo: i-p-toluidine yikristale engenambala, ekhazimlayo ejiyileyo, okanye i-solid emhlophe ukuya kwephuzi ekhanyayo, kwaye isenokubonakala inombala omdaka ukuya komdaka.
Ukunyibilika: Iyanyibilika kancinci emanzini, kodwa iyanyibilika kwiintlobo ngeentlobo zezinyibilikisi ezifana ne-ethanol, i-ether, i-benzene, kunye ne-hydrochloric acid.
Ezinye iimpawu zomzimba: Iqondo lokunyibilika: Ngokwesiqhelo phakathi kwama-41-46°C 23. Iqondo lokubila: 200°C (uxinzelelo oluqhelekileyo). Uxinano: Uxinano oluhambelanayo lumalunga ne-0.9619 ukuya kwi-0.973 g/mL (kwi-25°C). Isalathisi sokuchacha: Malunga ne-1.5534 ukuya kwi-1.5636 34. Iqondo lokutsha: Malunga nama-86°C okanye i-192°F. I-p-Toluidine isetyenziswa kakhulu njenge-dye intermediate kunye ne-intermediate ye-pyrimethamine yamayeza kushishino, kodwa kufuneka kuqatshelwe ukuba inetyhefu kwaye yi-methemoglobin enamandla, ngoko ke kufuneka isetyenziswe ngononophelo.
Ngamafutshane, i-p-toluidine ineefom ezininzi, kwaye iipropati zayo zomzimba ziyahluka ngokuxhomekeke kwifom kunye neemeko.
Ukusetyenziswa kwe-p-toluidine
I-reagent yohlalutyo: i-p-toluidine isetyenziswa njenge-reagent kwi-analytical chemistry ukunceda ekwenzeni uhlalutyo oluthile lweekhemikhali. Ukwenziwa kwedayi: Yinto ephakathi kweedayi ezininzi, ezifana ne-red base GL, i-methylamine red lake, i-basic fuchsin, kwaye isetyenziswa kakhulu ekuhlanganisweni kwedayi kwimizi-mveliso yelaphu, ushicilelo kunye neminye. I-Pharmaceutical intermediate: Kwicandelo le-pharmaceutical, i-p-toluidine yinto ephakathi kwe-pyrimethamine yeziyobisi, ebalulekileyo ekuhlanganisweni kwamayeza. Ezinye izicelo: i-p-toluidine ingasetyenziselwa ukulungiselela i-1-hydroxy-4-(p-toluidine)-anthraquinone, esetyenziswa njenge-reagent ebucayi yokumisela i-boron kwaye isetyenziselwa kakhulu ukufaka umbala kwi-polyester fiber pulp.
I-p-Toluidine, ekwaziwa ngokuba yi-4-toluidine, yi-organic compound ene-chemical formula ye-C7H9N. Yikristale engenambala, ekhazimlayo, enyibilikayo kancinci emanzini, kodwa inyibilika kwi-ethanol, i-ether, i-benzene, kunye ne-hydrochloric acid. Kufuneka kuqatshelwe ukuba i-p-Toluidine inetyhefu, i-methemoglobin enamandla, kwaye inokucaphukisa isinyi kunye ne-urethra kwaye ibangele i-hematuria, ngoko ke kufuneka isetyenziswe ngononophelo.
