Abstract (en)
[origin: WO03062174A1] The invention relates to a method for producing toluol derivatives of formula (I), in which R<1>, R<2>, and R<3> independently of one another represent hydrogen, halogen, C1-C6 alkyl, hydroxyl or C1-C6 alkoxy. Said derivatives are produced by the hydrogenation of benzaldehydes and/or benzylalcohols of formula (II), IIa: X=CHO X=CH[OC1-C6 alkyl]2, IIb: X=CH2-OH X=CH2OC1-C6 alkyl with hydrogen in the presence of a catalyst, which is defined in more detail in the description.
