Abstract
Способ получения изопрена путем контактирования 4,4-диметилдиоксана-1,3, изобутилена и/или триметилкарбинола в жидкой фазе с сульфокатионитом на основе дивинилбензола и стирола в присутствии воды при 120 - 150C, отличающийся тем, что, с целью повышения выхода изопрена и упрощения технологии процесса, используют сульфокатионит с размером частиц 10- 10см в виде 5 - 20 мас.%-ной водной суспензии.The method of producing isoprene by contacting 4,4-dimethyldioxane-1,3, isobutylene and / or trimethylcarbinol in the liquid phase with sulfonic cation exchanger based on divinylbenzene and styrene in the presence of water at 120-150 ° C, in order to increase the yield of isoprene and simplify The process technology uses sulfonic cation exchanger with a particle size of 10-10 cm in the form of 5-20% by weight of aqueous suspension.
