Изобретение огносигс к способу получени диеновых углеводородов, используемых в производстве сингегических каучуков .The invention of ognosigs to a method for the preparation of diene hydrocarbons used in the production of singular rubbers.
Извесген способ получени сопр жен- 5 ных диеновых углеводородов, в том числе изопрена, дегидрированием соогвегсгвую- ишх алканов или олефинов 1 .Izvesgen is a method of producing conjugated 5 diene hydrocarbons, including isoprene, by dehydrogenating co-alkanes or alkanes or olefins 1.
Недостатками способа вл ютс низка конверси сырь , невысокий выход продук- 0 та, необходимость сложной системы разде« лени продуктов реакции.The disadvantages of the method are the low conversion of the raw material, the low yield of the product, the need for a complex system for separating the reaction products.
Известен также способ получени сопр « женных диеновых углеводородов путем кон денсации олефина с альдегидом в присутст ВИИ катализатора при повышенной температуре с последующим выделением полученнь;х непредельных спиртов и их каталиги- ческим разложением при С 2.There is also known a method of obtaining conjugated diene hydrocarbons by condensation of an olefin with an aldehyde in the presence of a VIH catalyst at elevated temperature, followed by separation of the resulting unsaturated alcohols and their catalytic decomposition at C 2.
Недостатком способа вл етс сложност процесса, осуществл емого в двух реакто- pax с использсжанйем на каждой-стадии разных катализаторов. Значительные трудности представл ет утилизаци побочных продуктов.The disadvantage of the process is the complexity of the process carried out in two reactors using each stage of different catalysts. Considerable difficulties are the disposal of by-products.
Целью изобретени вл етс . упрощение процесса.The aim of the invention is. simplify the process.
Поставленна цель достигаетс способом получени сопр женных диеновых углеводородов в одном реакторе при прове дении конденсации термической обработкой исходных продуктов при 12О-2ОО С в первой по ходу зоне реактора с последующим каталитическим разложением полученной смеси во второй зоне, предпочтительно , при 24О-ЗООС.This goal is achieved by the method of producing conjugated diene hydrocarbons in a single reactor by conducting thermal treatment of the initial products at 12 0 -2 2 C in the first zone of the reactor, followed by catalytic decomposition of the mixture in the second zone, preferably at 24 0 -30.
Насто щий способ позвол ет практически полностью использовать альдегид - наиболее дорогосто щий из реагенте, получать целевой продукт в одном реакторе Н упростить сасгему разделени в очисрки целевого продукта.The present method allows the aldehyde, the most expensive of the reagent, to be used almost entirely, to obtain the desired product in a single reactor H, to simplify the separation system in the purification of the target product.
Способ предусматривает использование газообразного формальдегида, что позвол ет исключить из схемы его пронзво№ства узел получени формалина. Кроме тоThe method involves the use of formaldehyde gas, which makes it possible to exclude the formalin production unit from its projection scheme. Besides
