N,N-dihydroxyethyl-p-methylaniline ndi mankhwala omwe amagwiritsidwa ntchito kwambiri popanga utoto, mankhwala ndi mankhwala ophera tizilombo. Gulu la ester pagulu la terminal amino limapatsa utoto wamtunduwu zinthu zabwino kwambiri. Kuyambira kukonzekera kwake, wakhala akugwira msika wina

N,N-dihydroxyethyl-p-methylaniline ikhoza kupangidwa ndi njira zotsatirazi: onjezerani 1000g p-methylaniline ndi madzi 10g mu ketulo ya 5L yamphamvu, kwezani kutentha kwa 60 ° C ~ 65 ° C ndikugwedeza kwa mphindi 30, kenaka yikani. 100g ya ethylene oxide, sungani kutentha kwa 65 ~ 70 ℃ kwa 4h. Kenako onjezani 100g ya ethylene oxide Chemicalbook mkati mwa maola 4, sungani kutentha kwa 70-75 ° C, ikani pa 70-80 ° C kwa maola atatu mutadutsa, ndikuzizira mpaka 30 ° C. Onjezani yankho la momwe mungachitire mu ketulo ya distillation ndikusonkhanitsani mankhwalawo pa 143 ~ 148°C (1.3~1.6kPa). Zokolola ndi 86% ndipo chiyero cha mankhwala ndi chachikulu kuposa 98%. Gawo lakutsogolo likhoza kusinthidwanso kuti liwonjeze zokolola. Mankhwalawa ndi olimba achikasu.
