The invention discloses a method for preparing methylallyl alcohol from methyl alcohol and propyl alcohol. The method adopts a multi-component MgaZrbZncSidOe composite metal oxide catalyst and formaldehyde as initiators to efficiently synthesize the methylallyl alcohol. According to the method for preparing the methylallyl alcohol, the conversion rate of propyl alcohol can be greatly improved, andthe selectivity of the methylallyl alcohol is stably improved. In the whole reaction process, the selectivity of the methylallyl alcohol is 90% or over, and the single-pass conversion rate of the normal propyl alcohol is more than 30%, so that the preparation process of the methylallyl alcohol is more environmentally friendly, the cost is saved, and good industrial application prospects are achieved. 本发明公开了一种由甲醇和丙醇制备异丁烯醇的方法，该方法采用多组分MgZrZnSiO复合金属氧化物催化剂和甲醛作为引发剂高效地合成异丁烯醇。本发明的制备异丁烯醇的方法可以大幅度提高丙醇的转化率，异丁烯醇的选择性稳步提升。在整个反应过程中，异丁烯醇的选择性在90％以上，正丙醇的单程转化率大于30％。使异丁烯醇的制备工艺更加绿色环保、节约成本，有很好的工业化应用前景。
