Te āhua me ngā āhuatanga taketake o te p-toluidine

Āhua: he tioata pīataata, kore tae te p-toluidine, he mā ki te kōwhai mārama rānei te tae, ā, ka puta pea he āhua parauri ki te parauri.
Wairewatanga: He wairewa paku ki te wai, engari ka wairewa ki ngā momo whakarewa pēnei i te etanoru, te etera, te penehīni, me te waikawa hauwaiora.
Ngā āhuatanga ā-tinana kē atu: Te ira rewa: I waenganui i te 41-46°C 23. Te ira koropupū: 200°C (pēhanga noa). Te mātotoru: Ko te mātotoru whanaunga kei waenganui i te 0.9619 ki te 0.973 g/mL (i te 25°C). Te taupū whakaata: Tata ki te 1.5534 ki te 1.5636 34. Te ira mura: Tata ki te 86°C, 192°F rānei. Ko te p-Toluidine e whakamahia ana hei takawaenga tae me te takawaenga o te pyrimethamine rongoā i roto i te ahumahi, engari me mōhio he paitini, ā, he kaha ki te hanga methemoglobin, nō reira me tūpato te whakamahi.
Hei whakarāpopototanga, he maha ngā āhua o te p-toluidine, ā, he rerekē ōna āhuatanga ā-tinana i runga i te āhua me ngā āhuatanga.
Ngā whakamahinga o te p-toluidine
Kaiwhakaora tātari: ka whakamahia te p-toluidine hei kaiwhakaora i roto i te matū tātari hei āwhina i te mahi tātari matū motuhake. Te hanga tae: He takawaenga mō ngā tae maha, pērā i te GL turanga whero, te roto whero methylamine, te fuchsin taketake, ā, he whānuitia te whakamahinga i roto i te hanga tae i roto i te ahumahi kakahu, tā me ētahi atu ahumahi. Te takawaenga rongoā: I roto i te mara rongoā, ko te p-toluidine he takawaenga mō te pyrimethamine rongoā, he mea nui mō te hanga rongoā. Ētahi atu whakamahinga: ka taea hoki te whakamahi i te p-toluidine hei whakarite i te 1-hydroxy-4-(p-toluidine)-anthraquinone, e whakamahia ana hei kaiwhakaora tairongo mō te whakatau i te boron, ā, e whakamahia ana mō te tae o te penupenu muka polyester.
Ko te p-Toluidine, e mōhiotia ana ko te 4-toluidine, he matū rauropi me te tauira matū o C7H9N. He tioata kanapa, kore tae, he ngawari te wairewa ki te wai, engari ka wairewa ki te etanoru, te etera, te benzene, me te waikawa hauwaiora. Me mōhio he paitini te p-Toluidine, he kaha ki te hanga methemoglobin, ā, ka taea te whakararuraru i te pūkahukahu me te urethra, ka puta ai te hematuria, nō reira me tūpato te whakamahinga.
