Abstract :

In the present work, kinetics of synthesis of allyl phenyl ether was successfully carried out by O–allylation of phenol with allyl omide using aqueous KOH and catalyzed by a new multi – site phase – transfer catalyst viz., 1,3,5,7–tetrabenzylhexamethylenetetraminium tetrachloride, MPTC under ultrasonic ( 40KH_Z, 300W) assisted organic solvent condition. O–allylation of allyl omide has been achieved by controlling the reaction condition and has been followed using gas chromatogram. The effects of various parameters such as [stirring speed], [catalyst], [KOH], [allyl omide], volume of water ultrasonic frequency and temperature were studied systematically to understand their influence on the rate of the reaction. The experimental observations are consistent with an interfacial–type process. Further the kinetic results demonstrate clearly, that ultrasonic assisted phase– transfer catalysis significantly increased the reaction rate when compared to conventional method.
