Codsiga

N,N-dihydroxyethyl-p-methylaniline waa dhexdhexaad dabiici ah oo loogu talagalay midabaynta, daawooyinka, sunta cayayaanka, iwm. Kooxda ester-ka ee ku jirta kooxda amino-ka ee ugu dambeeya waxay ka dhigaysaa nooca rinjiga inuu leeyahay sifooyin aad u fiican. Waxay haysatay suuq gaar ah tan iyo markii la diyaariyey. Waqtigan xaadirka ah, baahida gudaha waa mid aad u weyn, weli waxaa jira awood suuq gaar ah oo dibadda ah. Barashada isku-darka iyo hab-socodkeeda waxay leedahay muhiimad dhaqaale iyo mid wax ku ool ah.

Habka isku-darka

N,N-dihydroxyethyl-p-methylaniline waxaa lagu samayn karaa tallaabooyinka soo socda: Ku dar 1,000 g oo p-methylaniline ah iyo 10 g oo biyo ah autoclave 5L ah, ku kululee 60 ℃ ~ 65 ℃ oo walaaq 30 daqiiqo, ka dibna ku dar 100 g oo ethylene oxide ah oo heerkulka ku hay 65 ~ 70 ℃ muddo 4 saacadood ah. Ka dibna ku dar 100 g oo ethylene oxide ah muddo 4 saacadood ah gudahood, heerkulka ku hay 70 ~ 75 ℃, ka falceli 70 ~ 80 ℃ muddo 3 saacadood ah ka dib markaad dhaafto, oo qabooji ilaa 30 ℃. Xalka falcelinta ayaa lagu daray digsiga distillation-ka, badeecadana waxaa lagu ururiyay 143-148°C (1.3-1.6 kPa), iyadoo wax soo saarku yahay 86% iyo daahirnimo ka badan 98%. Qaybta hore waa la dib u warshadayn karaa si loo kordhiyo wax soo saarka. Badeecadu waa mid adag oo huruud khafiif ah.
