Description
Пример. Смесь из 30 г фенола и 30 г этилового спирта (95%) в струе аммиака при 8-9 атм. давлени пропускаетс над окисью алюмини при температуре 375-400°. Скорость пропускани -15 г в час. После обработки продуктов реакции щелочью амины экстрагируютс эфиром, эфир отгон етс и амины взвешиваютс .Example. A mixture of 30 g of phenol and 30 g of ethanol (95%) in a stream of ammonia at 8-9 atm. pressure is passed over alumina at a temperature of 375-400 °. Transmission rate -15 g per hour. After treating the reaction products with alkali, the amines are extracted with ether, the ether is distilled off and the amines are weighed.
Полученные амины разгон ютс в пределах 195-230° и состо т из 1,5% первичных аминов анилина, 45% вторичных аминов моноэтиланилина и 53,5% третичных аминов диэтиланилина .The resulting amines are accelerated in the range of 195-230 ° and consist of 1.5% of the primary amines of aniline, 45% of the secondary amines of mono-ethylaniline and 53.5% of tertiary amines of diethylaniline.
. После обработки щелочного раствора кислотой может быть регенерировав непрореагировавщий фенол.. After treatment of the alkaline solution with an acid, it can be regenerated with unreacted phenol.
Общий выход аминов, счита на вз тый фенол, 58/2%.The total yield of amines, calculated on taken phenol, is 58/2%.
Измен температуру и скорость пропускани , можно измен ть соотношени между моно- и диэтиланилином .By varying the temperature and rate of transmission, the ratios between mono- and diethylaniline can be varied.
Измен соотношени фенола и спирта, провод реакцию в тех же услови х, увеличива количество спирта , можно получить смесь аминов, состо щих из 2,01% первичных, 7,3% вторичных и 90,6% третичных аминов.By varying the ratios of phenol and alcohol, conducting the reaction under the same conditions, by increasing the amount of alcohol, a mixture of amines consisting of 2.01% primary, 7.3% secondary and 90.6% tertiary amines can be obtained.
Предмет изобретени .The subject matter of the invention.
Способ получени моно- и диэтиланилина из фенола этилового спиртаThe method of obtaining mono - and diethylaniline from phenol ethyl alcohol
и аммиака, отличающийс тем, что смесь указанных реагентов пропускают при 400° над окисью алюмини .and ammonia, characterized in that the mixture of said reagents is passed at 400 ° over alumina.
