FIELD: chemistry. ^ SUBSTANCE: invention pertains to the method of separating polymerisation pure isobutylene by liquid phase contacting with a hydrocarbon fraction, containing isobutylene, with water in a column type reaction system in the presence of an acidic heterogeneous catalyst, located in the reaction zone(s) of the reaction system. Unreacted hydrocarbons are extracted. The tert-butanol formed is separated and directed for disintegration with formation of isobutylene. The method is characterised by that, the hydrocarbon fraction before contacting with water is mixed with isobutylene, obtained by disintegration of methyl-tert-butyl ether, in mass ratios ranging from 10:1 to 1:1.5. ^ EFFECT: higher efficiency of the process. ^ 3 cl, 1 tbl, 4 ex, 3 dwg |
