This paper presented the results of the experimental studies that are based on the influence of concentration of methylphenylcarbinol that is contained in wastewaters from petrochemical production on the pH of the reaction mixture. It is shown that in the ozonation, medium of the reaction mixture ranges from slightly alkaline to acidic one. As a result of the ozonization the organic acids, such as benzoic and formic acids, are formed. When methylphenylcarbinol concentration is higher than 0.0015 mol/l, a particular order on it varies from the first to the zero one. Under these conditions, a conversion of methylphenylcarbinol is observed up to 33%.at a temperature up to 28 °C for 15 min.
