Tono

He takawaenga waro te N,N-dihydroxyethyl-p-methylaniline mō ngā tae, ngā rongoā, ngā patupatu, me ētahi atu. Nā te rōpū ester i te rōpū amino whakamutunga, he pai ake ngā āhuatanga o tēnei momo tae. Mai i tōna hanganga, kua nohoia e ia tētahi mākete motuhake. I tēnei wā, he nui te tono ā-rohe, ā, kei te mau tonu tētahi pūmanawa mākete ki tāwāhi. He nui te hiranga o te ako i tōna hanganga me tana tukanga.

Tikanga whakahiato

Ka taea te hanga i te N,N-dihydroxyethyl-p-methylaniline mā ēnei mahi: Tāpirihia te 1,000 karamu o te p-methylaniline me te 10 karamu o te wai ki roto i te autoclave 5L, whakamahanahia ki te 60 ℃ ~ 65 ℃ ka whakaohokia mō te 30 meneti, kātahi ka tāpirihia te 100 karamu o te ethylene oxide ka pupuri i te pāmahana ki te 65 ~ 70 ℃ mō te 4 hāora. Kātahi ka tāpirihia te 100 karamu o te ethylene oxide i roto i te 4 hāora, pupuri i te pāmahana ki te 70 ~ 75 ℃, tauhohe ki te 70 ~ 80 ℃ mō te 3 hāora i muri i te whakawhiti, ka whakamatao ki te 30 ℃. I tāpirihia te otinga tauhohe ki te ipu whakatō, ā, i kohia te hua ki te 143-148°C (1.3-1.6 kPa), me te hua o te 86% me te parakore neke atu i te 98%. Ka taea te hangarua i te wāhanga o mua hei whakanui ake i te hua. He totoka kōwhai mārama te hua.
