| Abstract: | Solid base,KOH/Al_2O_3,was applied as a catalyst in a condensation reaction,and showed advantages over liquid bases.It avoided polluting environment and eroding equipments in using liquid base.In the synthesis of benzalacetone,the yield was above 88% after 3 h.The optimal reaction con- ditions were established:n(benzaldehyde):n(acetone)=1:4,the amount of catalyst is 2g,the best loadings of KOH in the catalyst is 12 mmol/g,reaction temperature is 40-45℃ and reaction time is 3 h. |
