Abstract: 1. A process for the preparation of 1-4-hydroxy-phenyl)-butan-3-one (I), wherein A. a corresponding 4-tert.-alkoxy-benzaldehyde of the general formula II see diagramm : EP0038480,P5,F2 where R is H or CH3 , is condensed with acetone under alkaline conditions to give the novel 1-(4-tert.-alkoxy-phenyl)-but-1-en-3-one of the general formula IIIa see diagramm : EP0038480,P5,F4 B. the latter is hydrogenated, during of after this condensation, to give the novel 1-(4-tert.-alkoxyphenyl)-butan-3-one of the formula IIIb see diagramm : EP0038480,P5,F6 and C. isobutene or 2-methyl-but-1(2)-ene is eliminated therefrom, at from 40 to 150 degrees C, in the presence of a catalytic amount of an acid.
