The p alkoxybenzaldehydes are key intermediates for synthesis of liquid crystalline materials. This paper reports a new method for synthesizing p alkoxybenzaldehydes from sodium p acylphenolate with n alkyl bromide or chloride at certain temperature in EtOH . By using this method, some compounds have been obtained in good yield. Some synthetic routes are illustrated and evaluated.
