文摘
- •
A solid SnF2-catalyzed process produced solketal from glycerol at room temperature.
- •
SnF2 catalyst was easily recovered and reused without loss activity.
- •
A process flow diagram with the best operating conditions was described.
- •
A mechanism for solid SnF2-catalyzed solketal synthesis was proposed.
- •
SnF2 operate in biphasic conditions with low proportion of glycerol to ketone.
