Year: 2026

Type: article

Abstract: This paper presents the results of a study on the catalytic activity of ZIF-14 synthesized from zinc acetate dihydrate in the condensation reaction between benzaldehyde (BA) with ethyl cyanoacetate (ECA). From the study of the effects of the BA : ECA molar ratio, catalyst content, temperature, and reaction time in ethanol solvent, the optimal reaction conditions for achieving BA conversion and ethyl α-cyanocinnamate (ECC) selectivity of 89.32 % and 92.16 %, respectively, were found to be a BA : ECA molar ratio of 1 : 1.5; 1.5 % catalyst (by weight of BA); a temperature of 50 °C; and a reaction time of 3 hours. The paper also showed that the crystalline structure of the catalyst was partially broken after each reaction. The catalyst could be reused up to 5 times, achieving BA conversion and ECC selectivity of 83.18 % and 90.86 %, respectively.
