Description
Предлагаетс способ получени метил (р-арил-этнл)-кетона нз 1-арил-3-хлор-2 бутена, мину стадию превращени его в дизамещенный виниловый эфир.A method is proposed for the preparation of methyl (p-aryl-ethnl) -ketone using 1-aryl-3-chloro-2 butene, after which it is converted to disubstituted vinyl ether.
Способ заключаетс в омылении фенплхлорбутена 92%-ной серной кислотой, после чего реакционную смесь разбавл ют водой и образовавшиес жирно ароматические кетоны, выдел ют известными приемами.The method consists in saponification of fenplchlorobutene with 92% sulfuric acid, after which the reaction mixture is diluted with water and the fatty aromatic ketones formed are isolated by conventional means.
Пример. Фенилхлорбутен обрабатываетс при +5° двойным по весу количеством 92%-ной серной кислоты при перемешивании. Через 16-28 час реакционную смесь выливают в холодную воду (или на кусочки льда). Отделенную органическую часть промывают водой, обезвоживают над сульфатом натри и перегон ют в вакууме. Полученный бензилацетон перегон ют при температуре кипени 111 -112°. Выход 51% от теоретического.Example. Phenylchlorobutene is treated at + 5 ° with a twofold amount of 92% sulfuric acid with stirring. After 16-28 hours, the reaction mixture was poured into cold water (or ice pieces). The separated organic portion is washed with water, dried over sodium sulfate and distilled in vacuo. The resulting benzylacetone is distilled at a boiling point of 111-112 °. Yield 51% of theoretical.
Предмет изобретени Subject invention
Способ получени метил (р-арил-этил)-кетонов на основе 1-арил-З-хлор-2-бутенов , получаемых по авт. св. № 65496, отличающийс тем, что на указанные исходные продукты действуют концентрированной серной кислотой, например 92%-ной, смесь разбавл ют водой и образовавшиес жирно-ароматические кетоны выдел ют известными приемами.The method of producing methyl (p-aryl-ethyl) -ketones based on 1-aryl-3-chloro-2-butenes, obtained by author. St. No. 65496, characterized in that the said starting materials are affected by concentrated sulfuric acid, for example 92%, the mixture is diluted with water and the fatty aromatic ketones formed are recovered by known techniques.
