| Abstract: | Butyraldehyde 1,2 - propanediol acetal was synthesized with butyraldehyde and 1,2 - propylene glycol as the materials and H4SiWI2Oa0/ZrO： - A1203 as the catalyst, and the effects of the ratio of reaction materials, catalyst amount, water carrier amount and reaction time, etc. on reaction were studied with orthogonal tests. According to the results of tests, the yield of butyraldehyde 1,2 - propanediol acetal can reach 82.6% at the optimized conditions as follows： n （butyraldehyde） ： n （1,2 -propanediol） = 1：1.5, catalyst consumption accounts for 1.5 % of total mass of reaction materials, amount of water carrier , i.e. cy- clohexane, is 8 mL, and reaction time is 1 h. |
