Abstract

Benzylation of o-cresol with benzyl alcohol (Bz-OH) in presence of 94% H2SO4 as catalyst was studied statistically with a two-levels threefactored   experimental design to study the effects of single factor and effects of their interactions on the yield of benzylated product. Reaction   temperature, molar ratio of o-cresol to Bz-OH and amount of 94% H2SO4 were considered as the major variables. A mathematical model   was derived to calculate the predicted yield of benzyl o-cresol as y = 0.419T+12.4055m+16.17w-0.0525Tm-2.606mw-   0.094Tw+0.0175Tmw-6.25; where, T = temperature (oC), m = o-cresol to Bz-OH molar ratio, w = amount of catalyst (% by wt. of o-cresol)   and y = yield. The adequacy of the suggested model was checked up and the discrepancies between the experimental and calculated values   did not exceed ± 0.79%.
