Kugwiritsa ntchito

N,N-dihydroxyethyl-p-methylaniline ndi chinthu chachilengedwe chomwe chimagwiritsidwa ntchito popanga utoto, mankhwala, mankhwala ophera tizilombo, ndi zina zotero. Gulu la ester lomwe lili pagulu la amino lomaliza limapangitsa kuti utoto wamtunduwu ukhale ndi makhalidwe abwino kwambiri. Wakhala ukugwira ntchito pamsika winawake kuyambira pomwe unapangidwa. Pakadali pano, kufunikira kwa anthu am'deralo ndi kwakukulu, ndipo pali mwayi wina pamsika kunja. Kuphunzira kapangidwe kake ndi momwe amagwirira ntchito kuli ndi tanthauzo lalikulu pazachuma komanso zothandiza.

Njira yopangira

N,N-dihydroxyethyl-p-methylaniline ikhoza kupangidwa motere: Onjezani 1,000 g ya p-methylaniline ndi 10 g ya madzi mu 5L autoclave, tenthetsani kufika 60 ℃ ~ 65 ℃ ndikusakaniza kwa mphindi 30, kenako onjezani 100 g ya ethylene oxide ndikusunga kutentha pa 65 ~ 70 ℃ kwa maola 4. Kenako onjezani 100 g ya ethylene oxide mkati mwa maola 4, sungani kutentha pa 70 ~ 75 ℃, chitani pa 70 ~ 80 ℃ kwa maola 3 mutadutsa, ndikuziziritsa kufika 30 ℃. Yankho la reaction linawonjezedwa mu distillation kettle, ndipo mankhwalawa anasonkhanitsidwa pa 143-148°C (1.3-1.6 kPa), ndi zokolola za 86% ndi chiyero choposa 98%. Gawo lakutsogolo likhoza kubwezeretsedwanso kuti liwonjezere zokolola. Chogulitsacho ndi cholimba chachikasu chopepuka.
