Abstract
Process for preparing 6-methylheptan-2-one, which comprises a) hydroformylation of isobutene to form 3-methylbutanal, b) base-catalyzed aldol condensation of the 3-methylbutanal with acetone to form 6-methylhept-3-en-2-one, with the molar ratio of 3-methylbutanal to the base used being more than 1:0.3 and c) hydrogenation of the 6-methylhept-3-en-2-one to give 6-methylheptan-2-one. The use of the 6-methylheptan-2-one prepared in this way for the preparation of isophytol, tetrahydrolinalool or dihydrogeraniol.
