Description

массы до 10-12°C, отдел ют продукт от катализатора декантацией. Оставшийс  катализатор используют дл  повторени  лроцесса.masses up to 10-12 ° C, separating the product from the catalyst by decantation. The remaining catalyst is used to repeat the process.

В результате получают 67,48 г продукта с составом, %:The result is 67.48 g of the product with the composition,%:

4-Хлор-2-метилбутен-239,694-Chloro-2-methylbutene-239,69

2-Хлор-2-метилбутен-34,91.2-Chloro-2-methylbutene-34.91.

Выход моногидрохлоридов изопрена на загруженный изопрен 98,0%.The output of monohydrochloride isoprene on the loaded isoprene 98,0%.

Моногидрохлориды отдел ют известным способом, например лерегопкой, но лучше полученную смесь без обработки направл ть на стадию получени  2-метилгептен-2-она-6.The monohydrochlorides are separated in a known manner, for example, by a lerebopka, but it is better to direct the resulting mixture to the 2-methylhepten-2-one-6 stage without treatment.

Предмет изобретени Subject invention

1. Способ получени  моногидрохлоридов изопрена путем взаимодействи  изопрена с1. A process for the preparation of isoprene monohydrochlorides by reacting isoprene with

безводным хлористым водородом в присутствии .катализатора - соединений одно- и/или двухвалентной меди с последующим выделением целевого продукта известными приемами , отличаюш,ийс  тем, что, с целью повышени  выхода целевого продукта, сокраш,ени  продолжительности и упрощени  технологического процесса, последний провод т в среде осушенного ацетона.anhydrous hydrogen chloride in the presence of a catalyst — compounds of mono- and / or divalent copper, followed by separation of the target product by known methods, is different because, in order to increase the yield of the target product, shorten the duration of the process and simplify the process, in the environment of dried acetone.

2.Способ по П. 1, отличающийс  тем, что .процесс ведут -при объемном соотношении ацетона и изопрена, равном 0,5-2.2. A method according to claim 1, characterized in that the process is carried out at a volume ratio of acetone and isoprene equal to 0.5-2.

3.Способ по пп. 1 и 2, отличающийс  тем, что процесс ведут при О-30°С.3. Method according to paragraphs. 1 and 2, characterized in that the process is conducted at O-30 ° C.

4.Способ ло пп. 1 и 3, отличающийс  тем, что катализатор берут в количестве 0,5- 5 вес. % в расчете на изопрен.4. Method of paras. 1 and 3, characterized in that the catalyst is taken in an amount of 0.5-5 weight. % based on isoprene.
