GWIRITSANI NTCHITO
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. Chiyambireni kukonzekera kwake, izo zakhala zikugwira msika wina. Pakali pano, zofuna zapakhomo ndi zazikulu, ndipo pali mwayi wina wamsika kunja kwa dziko. Kuwerenga kaphatikizidwe kake ndiukadaulo kuli ndi tanthauzo lalikulu pazachuma komanso zothandiza.

Synthesis njira
N,N-dihydroxyethyl-p-methylaniline ikhoza kupangidwa ndi njira zotsatirazi: kuwonjezera 1000g p-methylaniline ndi madzi 10g mu ketulo ya 5L, kwezani kutentha kwa Chemicalbook mpaka 60 ℃~65 ℃, yambitsani kwa mphindi 30, ndi kuwonjezera ethylene. oxide Onjezani 100g ya alkane ndikusunga kutentha kwa 65-70 ° C kwa maola anayi. Kenaka yikani 100g ya ethylene oxide 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.
