Investigations on the allylation of phenol with allyl acetate were carried out using H beta -30 catalyst. The allylation of phenol (molar ratio of AAc: phenol = 1:1) gave mainly allyl phenyl ether along with C-allylated products (ortho- and para-allyl phenols) at 90 degreesC in a stirred vessel. When phenol is taken in excess and at higher temperatures side reactions like polymerization was observed. The rate dependence study indicated that the rate of allylation has a first-order dependence with respect to catalyst, allyl acetate and phenol concentration. From the study on the effect of temperature, the rates of allylation were plotted as -In(rate) versus 1000/T (Arrhenius plot) and the activation energy E-a evaluated was found to be 7.12 kcal mol(-1). Based on the above observations, a speculative mechanism for allylation of phenol catalyzed by H beta -30 has been proposed.
