Synthesis of cyclohexanone-formaldehyde resin catalyzed by rehydrated Mg-Al hydrotalcite

- Mg-Al hydrotalcite is rehydrated to improve its basicity through a liquid method.
- Rehydrated Mg-Al hydrotalcite is used to catalyze aldol condensations in preparation of cyclohexanone-formaldehyde resin.
- The phase transfer catalyst CTAB is introduced to enhance the mass transfer among liquid-liquid-solid tri-phases.
- The reutilization and regeneration of rehydrated Mg-Al hydrotalcite is investigated.
