With strongly acidic cation exchange resin of styrene system used as catalyst,synthesis of butanone 1,2-propanediol ketal was produced by the reaction of 2-butanone and 1,2-propanediol.The effect of reaction time,materials ratio,the content of catalyst,the water-carrying agent and dosage,repetition experiment of catalyst on the synthesis were all studied.Therefore,the favorite technological conditions are presented as following： reaction time is 2 h,n（2-butanone） ∶ n（1,2-propanediol） = 0.2 ∶ 0.26,the water-carring agent（cyclohexane） is 40 mL,the amounts of strongly acidic cation exchange resin is 1.2 g（when 2-butanone is 0.2 mol）.The yield of product is 86.29%,w98.5%.The catalyst can be reused without any treatments.
