N,N-dihydroxyethyl-p-methylaniline hiki ke synthesized e kēia mau ʻanuʻu: e hoʻohui i 1000g p-methylaniline a me 10g wai i loko o ka ipu hao 5L, hoʻokiʻekiʻe i ka mahana i 60 ° C ~ 65 ° C a hoʻoulu i 30 mau minuke, a laila hoʻohui. 100g o ka ethylene oxide, mālama i ka mahana ma 65 ~ 70 ℃ no 4h. A laila e hoʻohui i ka 100Chemicalbookg ethylene oxide i loko o 4h, e mālama i ka mahana ma 70 ~ 75 ℃, e pane ma 70 ~ 80 ℃ no 3h ma hope o ka hele ʻana, a maʻalili i 30 ℃. E hoʻohui i ka hopena hopena i ka ipu hoʻoheheʻe a hōʻiliʻili i ka huahana ma 143 ~ 148 ℃ (1.3 ~ 1.6kPa). ʻO 86% ka hua a ʻoi aku ka maʻemaʻe o ka huahana ma mua o 98%. Hiki ke hana hou ʻia ka hakina mua e hoʻonui i ka hua.
