Abstract
A process for the continuous separation and recovery of isobutene from an isobutene-containing hydrocarbon mixture, comprising the steps of contacting the mixture with water to obtain a tertiary butanol-containing mixture, separating this mixture into hydrocarbon and aqueous layer, distilling the hydrocarbon layer to obtain a tertiary butanol-rich stream, dehydrating the thus obtained stream to obtain an isobutene-containing gaseous mixture and then introducing the thus obtained mixture into a distillation means to recover isobutene as the product therefrom.
