Title: Synthesis of n-octylaldehyde 1,2-propylene glycol acetal with silica supported ferric sulfate as catalyst
Abstract: n-Octylaldehyde 1,2-propylene glycol acetal was synthesized from n-octylaldehyde and 1,2-propanediol with silica supported ferric sulfate as catalyst. The effects of mole ratio of reactants,reaction time and catalyst dosage on the yield of n-octylaldehyde 1,2-propylene glycol acetal were examined.Experimental results showed that the optimal reaction conditions are: based on n-octylaldehyde 0.1 mol,the molar ratio of n(n-octylaldehyde)∶n(1,2-propanediol)=1.0∶1.1,the dosage of catalyst 1.0% of the total mass of the reactants,the amount of cyclohexane used as water carrying agent 12 mL,reaction time 3.0 h.The yield achieves 92.3%.
