| 摘 要： | Acetalization of glycol with carbonyl compounds was carded out catalyzed by cupric p-toluenesulfonate. These carbonyl compounds included cyclohexanone, propionoaldehyde, n-butyraldehyde, /so-butyraldehyde, n-valeraldehyde, benzaldehyde and butanone. Satisfactory results were obtained： the conversions of these carbonyl compounds were more than 90%, the selectivities were higher than 99.1%, only 0.1% mole ratio of catalyst to substrate and 90 min were sufficient in most cases. The catalyst and products were separated easily by phase separation.

| Abstract: | Acetalization of glycol with carbonyl compounds was carried out catalyzed by cupric p‐toluenesulfonate. These carbonyl compounds included cyclohexanone, propionoaldehyde, n‐butyraldehyde, iso‐butyraldehyde, n‐valeral‐ dehyde, benzaldehyde and butanone. Satisfactory results were obtained:the conversions of these carbonyl compounds were more than 90%, the selectivities were higher than 99.1%, only 0.1% mole ratio of catalyst to substrate and 90 min were sufficient in most cases. The catalyst and products were separated easily by phase separation. |
