Abstract: The invention relates to a method for producing biphenols of general formula (I) by reacting monophenols of general formula (II), wherein the radicals R1, R2 and R3 independently represent hydrogen, alkyl, aryl or arylalkyl, with 1 - 10 C-atoms, in the presence of an oxidation agent in a reactor. Said method is characterised in that a) the reactor does not contain any stationary integrated components which act as a current agitator, b) a maximum of 0,6 mol of oxidation agents are used per mol of monophenol, and c) the oxidation agent is added in a continuous or discontinuous manner in a plurality of portions within a time span of between 10 min - 24 hours, whereby the amount of oxidation agent which is added per time unit is not constant over the entire tine span, but is varied.

Abstract: A process for preparing biphenols of the general formula I by reaction of monophenols of the general formula II where the radicals R1, R2 and R3 are each, independently of one another, hydrogen, alkyl, aryl or arylalkyl having from 1 to 10 carbon atoms, in the presence of an oxidant in a reactor, wherein a) the reactor comprises no stationary internals which act as baffles, b) a total of not more than 0.6 mol of oxidant is used per one mol of monophenol, and c) the oxidant is introduced either continuously or discontinuously in a plurality of portions over a period of from 10 minutes to 24 hours, with the amount of oxidant introduced per unit time not being constant over the total period of time but instead being varied.
