Summary:The invention discloses a preparation method for 3-methyl-3-butene-1-ol. The preparation method comprises the following steps of causing water, transition metal salt, isobutylene and formaldehyde to enter a condensation reactor, and performing condensation reaction under the conditions of 300 to 360 DEG C and 5 to 25MPa, wherein the transition metal salt is one or two or more of vanadium, chromium, iridium, iron, rhenium, ruthenium, cadmium, platinum, cerium, praseodymium, neodymium, samarium, europium, terbium, dysprosium, thulium and the like, the condensation reaction can be completely implemented within 1 to 100s under the synergistic catalysis of transition metal ions and [H3O<+>], and only a small amount of isobutylene is required; performing light component removal, dehydration and heavy component removal on condensation reaction liquid to obtain high-purity 3-methyl-3-butene-1-ol.
