Abstract
Application field: the substituted phenols production. Summary of the invention: the substances of formula: (R1)(R2) (R3)(R4)(R5)C6OH where (R1)-(R5)-H provided that at least R1 or R5-H or C1-C6 cycloalkil, aryl, arylkyl, aminogroup or nitrogroup. The conditions of reaction: synthesis is carried out by decarboxilation with further hydrolysis of corresponding carboxilic acid in the liquide phase in presence of the dissolved copper containing catalyst, forming copper arylcarboxilate. By that the catalyst is at first oxidized with gas oxygen at 120-190°C and that it is subjected to reaction with arylcarboxilic acid in the oxigenless medium in presence of water, taken in 40-200 fold molar excess relative to the formed arylcarboxylarylcarboxilate quantity at 225-270°C and pressure of 0,1-2,5 MPa. The prepared substituted phenol is separated by distillation, and the catalyst is returned in the reaction zone for reusing.
