Abstract:The synthesis of cyclohexanone 1,2-propylene glycol ketal from cyclohexanone and 1,2-propylene glycol under the presence of catalyst rare earth solid superacid SO42-/TiO2 /Ce(Ⅳ) was studied.The influent factors on reaction were investigated.The results showed that the appropriate conditions were as follows:molar ratio of cyclohexanone and 1,2-propylene glycol was 1 ∶ 1.5,the amount of catalyst was 1.7% of the total weight of cyclohexanone and 1,2-propylene glycol,the amount of cyclohexane was 30% of the wei... |
Key words:cyclohexanone 1; 2-propylene glycol ketal; SO42-/TiO2 /Ce(IV); catalysis; ketalation |
