Isicelo

I-N,N-dihydroxyethyl-p-methylaniline iyi-organic intermediate yamadayi, imithi, izibulala-zinambuzane, njll. Iqembu le-ester eqenjini lama-amino elisekugcineni lenza lolu hlobo lwedayi lube nezakhiwo ezinhle kakhulu. Luye lwahlala emakethe ethile selokhu lwalungiswa. Njengamanje, isidingo sasekhaya sikhulu, futhi kusekhona amandla athile emakethe kwamanye amazwe. Ukufunda ukuhlanganiswa kwayo kanye nenqubo yayo kunokubaluleka okukhulu kwezomnotho nokusebenzayo.

Indlela yokwenziwa

I-N,N-dihydroxyethyl-p-methylaniline ingakhiwa ngezinyathelo ezilandelayo: Engeza u-1,000 g we-p-methylaniline kanye no-10 g wamanzi ku-autoclave engu-5L, ufudumale kufike ku-60 ℃ ~ 65 ℃ bese uvuselela imizuzu engama-30, bese ufaka u-100 g we-ethylene oxide bese ugcina izinga lokushisa lifike ku-65 ~ 70 ℃ amahora ama-4. Bese ufaka u-100 g we-ethylene oxide zingakapheli amahora ama-4, gcina izinga lokushisa lifike ku-70 ~ 75 ℃, sabela ku-70 ~ 80 ℃ amahora ama-3 ngemva kokudlula, bese uphola kufike ku-30 ​​℃. Isixazululo sokusabela sanezelwa eketheni yokucwilisa, futhi umkhiqizo waqoqwa ku-143-148°C (1.3-1.6 kPa), ngesivuno esingu-86% kanye nobumsulwa obungaphezu kuka-98%. Ingxenye engaphambili ingaphinde isetshenziswe ukuze kwandiswe isivuno. Umkhiqizo uyisithako esiphuzi esikhanyayo.
