Noi

ʻO N,N-dihydroxyethyl-p-methylaniline kahi mea waena organik no nā kala, nā lāʻau lapaʻau, nā pesticides, a me nā mea ʻē aʻe. ʻO ka hui ester ma ka hui amino terminal e hoʻolilo i kēia ʻano kala i nā waiwai maikaʻi loa. Ua noho ia ma kahi mākeke mai kona hoʻomākaukau ʻia ʻana. I kēia manawa, nui ka noi kūloko, a aia nō kekahi hiki ke kūʻai aku ma waho. He mea nui ka hoʻonaʻauao ʻana i kāna synthesis a me ke kaʻina hana.

ʻAno hana hoʻohui

Hiki ke hoʻohui ʻia ʻo N,N-dihydroxyethyl-p-methylaniline ma o kēia mau ʻanuʻu: E hoʻohui i 1,000 g o ka p-methylaniline a me 10 g o ka wai i kahi autoclave 5L, e hoʻomehana i 60 ℃ ~ 65 ℃ a hoʻoulu no 30 min, a laila e hoʻohui i 100 g o ka ethylene oxide a mālama i ka mahana ma 65 ~ 70 ℃ no 4 h. A laila e hoʻohui i 100 g o ka ethylene oxide i loko o 4 h, e mālama i ka mahana ma 70 ~ 75 ℃, e pane ma 70 ~ 80 ℃ no 3 h ma hope o ka hala ʻana, a e hoʻomaʻalili i 30 ℃. Ua hoʻohui ʻia ka hopena hopena i ka ipu distillation, a ua hōʻiliʻili ʻia ka huahana ma 143-148°C (1.3-1.6 kPa), me ka hua o 86% a me ka maʻemaʻe ma mua o 98%. Hiki ke hana hou ʻia ka ʻāpana mua e hoʻonui i ka hua. He paʻa melemele māmā ka huahana.
