A compound of 4-hydroxybenzaldehyde-4-hydroxybenzoyl hydrazone was ultrasonic wave syn-thesized through the condensation of 4-hydroxybenzaldehyde and 4-hydroxybenzoyl hydrazine. The effects of the amount of solvent and the reaction time on the yield was discussed. The compound was character-ized by elemental analysis and infrared spectroscopy. The thermogravimetric analysis shows that the com-pound is stable below 66 ℃.
