Abstract
Solid base Na2CO3/γ-Al2O3 and NaOH/γ-Al2O3 were prepared and applied in the synthesis of trimethylolethane from propionaldehyde and formaldehyde by two step reactions.When the weak solid base Na2CO3/γ-Al2O3 catalyst amount was 1g,37% formaldehyde 60mL and 20mL 98% propionaldehyde were used as atarting materials,aldol condensation temperature was 35℃,reaction for 3h.After that,Na2CO3/γ-Al2O3 was separeted from the obtained mixture,1g NaOH/γ-Al2O3 was put into as Cannizzero reaction catalyst reaction for 3h at 70℃,the yield of trimethylolethane was high up to 86.2%.
