    Abstract: PROBLEM TO BE SOLVED: To provide a simpler process for preparing N-benzylamine. SOLUTION: This process for preparing the N-benzylamine comprises (i) in a first step, reacting benzaldehyde with a primary amine and providing an imine and (ii) in a second step, hydrogenating the imine with hydrogen in the presence of a catalyst containing one or more kinds of metals of groups 8 to 10 of the periodic table of elements and affording the N-benzylamine, wherein the imination (i) is carried out in a water-miscible solvent without removing formed water of reaction and the hydrogenation (ii) is carried out in the imine solution obtained by the imination (i) and containing the water of reaction.

    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.
