“…Catalytic alkylation of isomeric cresols with different alcohols and esters have been studied by several research groups [7][8][9][10][11][12][13][14][15][16] . Reports are also available on the alkylation of isomeric cresols with olefins and styrene in presence of different catalysts [17][18][19][20][21][22] , while alkylation of ocresol with alkenes especially cyclohexene was not studied so much. With the best of our knowledge only alkylation of o-, m-, and p-cresols with cyclohexene in the presence of aluminum cresolates have been studied 23 .…”

Alkylation of o-cresol with cyclohexene in the presence of perchloric acid as catalyst was studied statistically with a three-factored experimental design. Factorial design was employed to study the effects of single factors and the effects of their interactions on the yield of alkylation. Reaction temperature, molar ratio of o-cresol to cyclohexene and amount of perchloric acid were considered as the major variables. A mathematical model was derived to calculate the predicted yield of alkylation of o-cresol with cyclohexene in the presence of perchloric acid under certain reaction conditions and cyclohexyl o-cresol was obtained in high yield. The adequacy of the suggested model was checked up and the discrepancies between the experimental and calculated values did not exceed 1.52%. An optimum yield (89.5%) of the product was obtained under the reaction conditions of a temperature of 140º C; a 6:1 molar ratio of ocresol to cyclohexene and a 5% by weight perchloric acid of o-cresol.
