Description
Описываемый способ получени р-аминокетонов по сравнению с известным повышает выход продукта. Это достигаетс тем, что реакцию ведут ь присутствии катионитов./The described method of producing p-aminoketones, as compared with the known, increases the yield of the product. This is achieved by the fact that the reaction is conducted in the presence of cation exchangers.
При м ер- К спиртовому раствору, содержащему 5,4 г бензальацетопа и 3,5 г хлоргпдрата диметиламина добавл ют 1,4 г параформа и 0,5 2 катиопита, например, марки СБС-1. Смесь нагревают при температуре 70° и перемешивапии в течение одного часа; затем гранулы катионита легко отфильтровывают и снирт отгон ют. Полученный хлоргидрат р-дйметиламинобензальбутанона высушивают. Выход продукта составл ет 5,8 г или 66,5%.At mead To a alcohol solution containing 5.4 g of benzalacetopa and 3.5 g of dimethylamine chlorhydrate, 1.4 g of paraform and 0.5 2 of cationite, for example, grade SBS-1, are added. The mixture is heated at a temperature of 70 ° and stirring for one hour; then the cation exchanger granules are easily filtered off and removed. The p-dimethylaminobenzalbutanone hydrochloride obtained is dried. The product yield is 5.8 g or 66.5%.
Катализируюшее действие катионитоЕ, проверено также на кетонах жирного р да (ацетон), жирноароматического р да (ацетофенон) со значительным увеличением выходов соответствующих р-аминокетонов.The catalyzing effect of cation-A is also tested on fatty ketones (acetone), fatty-aromatic row (acetophenone) with a significant increase in the yields of the corresponding p-amino ketones.
Предмет изобретени Subject invention
Способ получени р-аминокетонов взаимодействием аминов с кетонами и формальдегидом, отличающийс тем, что, с целью повыщени выхода, реакцию Е;едут в присутствии катионитов.A method for producing p-amino ketones by reacting amines with ketones and formaldehyde, characterized in that, in order to increase the yield, reaction E is carried out in the presence of cation exchangers.
