The invention discloses a method for preparing unsaturated ketone. According to the method, an unsaturated alcohol and 2-alkoxy propylene are adopted as raw materials, an acid resin in a fixed bed aremodified, a Saucy-Marbet reaction is carried out, and unsaturated ketone is synthesized with high selectivity and high yields. According to the method, the modified acid resin is adopted as a catalyst, the problem that a common acid resin is poor in catalysis effect is solved; in addition, a fixed bed reactor is adopted to catalyze reactions, separation of the catalyst from reaction products before and after reactions can be achieved, equipment corrosion and adverse influence of a great amount of acids upon later industrial aftertreatment can be avoided, and the method is an economic and efficient synthesis method.
