Isicelo

I-N,N-dihydroxyethyl-p-methylaniline sisixhobo esiphakathi se-organic sedayi, amayeza, izibulali-zinambuzane, njl. Iqela le-ester kwiqela le-terminal amino lenza olu hlobo lwedayi lube neempawu ezibalaseleyo. Ithathe indawo kwimarike ethile ukusukela oko yalungiswa. Okwangoku, imfuno yasekhaya inkulu, kwaye kusekho amandla athile emarike kwamanye amazwe. Ukufunda ukwenziwa kwayo kunye nenkqubo yayo kubaluleke kakhulu kwezoqoqosho nangokwemisebenzi.

Indlela yokwenziwa

I-N,N-dihydroxyethyl-p-methylaniline inokwenziwa ngala manyathelo alandelayo: Yongeza i-1,000 g ye-p-methylaniline kunye ne-10 g yamanzi kwi-autoclave ye-5L, ufudumale uye kwi-60 ℃ ~ 65 ℃ uze uvuse imizuzu engama-30, uze wongeze i-100 g ye-ethylene oxide uze ugcine ubushushu bukwi-65 ~ 70 ℃ iiyure ezi-4. Emva koko yongeza i-100 g ye-ethylene oxide ngaphakathi kweeyure ezi-4, gcina ubushushu bukwi-70 ~ 75 ℃, sabela kwi-70 ~ 80 ℃ iiyure ezi-3 emva kokudlula, uze upholise uye kwi-30 ℃. Isisombululo sempendulo songezwa kwi-distillation kettle, kwaye imveliso yaqokelelwa kwi-143-148°C (1.3-1.6 kPa), enesivuno se-86% kunye nobumsulwa obungaphezulu kwe-98%. Inxalenye engaphambili ingaphinda isetyenziswe ukuze kwandiswe isivuno. Imveliso iluphawu olutyheli olukhanyayo.
