ABSTRACT:
The 3-methyl-3-butene-1-ol contained in the oily mixture obtained in the production of isoprene by the reaction of isobutene and formaldehyde through the intermediate 4,4-dimethyl-1,3-dioxane can be isolated by adding boric acid to said mixture to form the boric acid ester of 3-methyl-3-butene-1-ol and recovering the higher boiling fraction having a boiling point of above 160.degree.C.
