Abstract
A process for the preparation of a phenolic resin which comprises reacting a phenol with a peroxidase or an oxidase enzyme and a peroxide in an organic solvent containing medium to generate phenolic radicals which react to form a phenolic resin.
Claims41
A process for preparing a phenolic dimer or trimer which comprises reacting a phenol at a concentration of at least 1 g/100 ml with a peroxidase or an oxidase enzyme and a peroxide or oxygen in a medium containing an organic solvent and water in a volumetric ratio of 1/10 to 10/1 to produce a dimer or a trimer of said phenol wherein said phenol is dissolved in said organic solvent, and recovering said dimer or trimer.
