Abstract
Способ очистки изопрена, выделенного из продуктов синтеза его на основе изобутилена и формальдегида, от примесей, мешающих стереорегулярной полимеризации, путем экстрактивной ректификации в присутствии разделяющего агента, отличающийся тем, что, с целью снижения энергозатрат, в качестве разделяющего агента используют высококипящий побочный продукт, образующийся на стадиях синтеза или разложения диметилдиоксана в изопрен в процессе его производства из изобутилена и формальдегида, или высококипящий побочный продукт, образующийся в процессе одностадийного производства изопрена из изобутилена и формальдегида.The method of purification of isoprene, isolated from the products of its synthesis on the basis of isobutylene and formaldehyde, from impurities that interfere with stereoregular polymerization, by extractive distillation in the presence of a separating agent, characterized in that, in order to reduce energy consumption, a high-boiling byproduct formed at the stages of the synthesis or decomposition of dimethyldioxane into isoprene during its production from isobutylene and formaldehyde, or a high-boiling by-product formed in The process of one-stage production of isoprene from isobutylene and formaldehyde.
