Abstract (en)
[origin: WO2005056508A1] The invention relates to a method for the production of tetrahydrogeranylacetone (tetrahydropseudoionone) by means of aldolcondensation of citral with acetone and subsequent hydrogenation. The invention also relates to the utilization of the tetrahydrogeranylacetone thus obtained for the production of phytol, isophytol, tocopherol and/or tocopherol derivatives. The invention further relates to methods for the production of tocopherols and/or tocopherol derivatives.
