Description
Неорганический осадок - бромистоводородную соль триэтиламина отфильтровывают, фильтрат перегон ют в вакууме.The inorganic precipitate — triethylamine hydrobromide is filtered off and the filtrate is distilled in vacuo.
Выдел ют 130 г (80%) М,Н-диэтил-п-аминофенола; т. кип. 145-147°С/12 мм рт. ст., « 1,5600.130 g (80%) of M, H-diethyl-p-aminophenol were isolated; m.p. 145-147 ° C / 12 mm Hg Art., "1.5600.
Пример 2. 21,8 г (0,2 моль) tt-аминофенола раствор ют в 100 мл диметилформамиде, приливают при перемешивании 15 мл (0,2 моль) бромистого этила. Реакци экзотермична; после охлаждени реакционной среды до комнатной температуры при перемешивании приливают 27,6 мл (0,2 моль) триэтиламина . Выпавший осадок отфильтровывают , фильтрат перегон ют.Example 2. 21.8 g (0.2 mol) of tt-aminophenol are dissolved in 100 ml of dimethylformamide, 15 ml (0.2 mol) of ethyl bromide are added with stirring. The reaction is exothermic; after cooling the reaction medium to room temperature, 27.6 ml (0.2 mol) of triethylamine are added with stirring. The precipitate formed is filtered off and the filtrate is distilled.
Выдел ют 25 г (92%) М-моноэтил-«-аминофенола; т. пл. 107°С.25 g (92%) of M-monoethyl - "- aminophenol; m.p. 107 ° C.
