Japanese Patent Application Laid-Open Publication No. H11-176,086 describes a method for producing a high molecular weight phenol resin in a homogeneous mixed solvent composed of an organic solvent and water using an enzyme catalyst and a peroxide. Since this method uses an enzyme present in a living body as a catalyst, it is excellent in that no harmful waste derived from the catalyst is generated. However, in this method, it was difficult to produce a low molecular weight phenol condensate, particularly a phenol dimer condensate, in high yield.

The inventors have found that the above problem can be solved by using a mixed solvent composed of a water-soluble organic solvent and water, and have completed the present invention. That is, in the present invention, a peroxide is dividedly added in the presence of an enzyme catalyst, and when phenol is oxidatively coupled in a solvent, a mixed solvent comprising a poorly water-soluble or water-insoluble organic solvent and water is used as the solvent. And a method for producing a phenol dimer condensate.
