Abstract
The reaction of urea with aromatic aldehydes (X - CHO, X =H, Br, Cl, NO2, OCH3) was carried out in alcohol using potassium hydroxide as a catalyst. In the reaction of urea with aliphatic aldehydes alkylol ureas have been obtained, but in this work the reaction products were alkylethers of p-substitutedbenzylol ureas. and only in the reaction of urea with p-nitrobenzaldehyde at room temperature p-nitrobenzylol urea was obtained. The reaction path was also investigated by thin layer chromatography. From these results, it is assumed that owing to K+and the electron attracting nature of p-substitutedphenyl nuclei the etherification between p-substitutedbenzylol urea and alcohol used as the reaction solvent arises more easily in the reaction of urea with aromatic aldehyde than with aliphatic aldehyde.
