| Abstract: | Benzaldehyde 1,2-propanediol acetal was synthesized from benzaldehyde and 1,2-propanediol in the presence of dodecyl sulfonic acid iron.The effect of reaction time,the amount of catalyst,the molar ratio of raw materials and water carrying agent on the product yield was investigated respectively.Experimental results demonstrate that dodecyl sulfonic acid iron is a good catalyst for preparation of benzaldehyde 1,2-propanediol acetal.The optimized conditions are as follows: mole ratio of benzaldehyde to 1,2-pr... |
