چکیده
|
This paper reports the preparation and characterization of poly(4-vinylpyridine) (p4vp) supported on al2o3-sio 2 and its application for knoevenagel condensation reaction of various aldehydes with ethyl cyanoacetate in water as a green solvent. the results illustrate that the sample containing 0.6 molar ratio of al to si exhibits the highest yield (98%) in the reaction of benzaldehyde with ethyl cyanoacetate with 100% selectivity to the arylidene derivative. © 2012 majid kolahdoozan et al.
