Method for synthesizing isopentenol from butenol

The invention is suitable for the technical field of a synthetic method for isopentenol and provides a method for synthesizing isopentenol from butenol. The method is a method for isomerizing double bonds of 3-methyl-3-butenol under the catalytic action of a catalyst composed of solid super base and aluminium isopropoxide, wherein the solid super base is Na-Na2CO3/gamma-Al2O3, the dosage of the catalyst is 0.2-12% of 3-methyl-3-butenol, and the mass ratio of the solid super base and aluminium isopropoxide in the catalyst is 1: 1 to 1: 2. The reaction pressure is 0.5-4MPa, the temperature is 100-140 DEG C and the time is 2-3 hours. The method provided by the invention is mild in reaction condition, the catalyst is high in activity and easy to separate and can be repeatedly used, the method is low in production cost, environmental-friendly and safe in production, and the product is high in purity and selectivity and green and environmental-friendly, so that the cost is greatly lowered, and the method is an efficient and economical synthetic method and has a wide prospect.
