The optimization of the process of catalytic cycloalkylation of phenol with methyl-cyclohexanes

The paper studies the regularities of the reaction of catalytic cycloalkylation of phenol with methyl-cyclohexane in the presence of ceolite-U saturated with ortho-phosporic acid. To obtain a target product with the maximum yield, the effect of input variables, i.e. reaction temperature, duration, mole ratio of the initial components, and the catalyst amount has been analyzed. Mathematic interpretation of the experimental data enabled to obtain individual dependences of the output parameter of each input factor in the form of an equation of the second order. The generalized equation of the dependence of the output parameter of the optimization simultaneously on the all input variables has been developed. The optimum conditions of the reaction of obtaining para- (methylcyclo-hexyl) of phenol have been specified.
