Abstract

The present invention relates to a process for recovering 3-methylbut-3-en-1-ol from a feed stream F1 comprising 3-methylbut-3-en-1-ol, one or more solvents, water, and isobutene, wherein 3-methylbut-3-en-1-ol, the one or more solvents and water are separated from isobutene by distillation, the process comprising subjecting the feed stream F1 to distillation conditions in a distillation unit, obtaining a bottoms stream B1 which is enriched in -methylbut-3-en-1-ol, in the one or more solvents and in water compared to the feed stream F1 subject The present invention relates to a process for recovering 3-methylbut-3-en-1-ol from a feed stream F1 comprising 3-methylbut-3-en-1-ol, one or more solvents, water, and isobutene, wherein 3-methylbut-3-en-1-ol, the one or more solvents and water are separated from isobutene by distillation, the process comprising subjecting the feed stream F1 to distillation conditions in a distillation unit, obtaining a bottoms stream B1 which is enriched in -methylbut-3-en-1-ol, in the one or more solvents and in water compared to the feed stream F1 subjected to distillation conditions, and a top stream T1 which is enriched in isobutene, further subjecting t…
