Page/Page column 5, (2008/06/13)
Process for esterification of farnesol in an initial mixture comprising alpha-bisabolol, farnesol and optionally other components, with the following steps: 1. Preparation or production of the initial mixture, 2. Adding (i) a transesterification catalyst and (ii) one or more compounds of formula (B) [in-line-formulae]R2YnCO2R1??(B) [/in-line-formulae] in which the following applies: R1 stands for an alkyl residue with 1 to 12 C atoms; R2 stands for hydrogen, an alkyl residue with 1 to 20 C atoms, a cycloalkyl residue with 5 to 20 C atoms, an aryl residue with 6 to 20 C atoms or a heteroaryl residue with 5 to 20 C atoms; and Y stands for CH2, CH(Me), CH(Et), C(Me)2, CH2—CH(Me), CH(Me)-CH2 or CH2—CH(Me)-CH2 and n stands for a whole number from 0 to 6; or R2 stands for a group CO2R3, R3 standing for an alkyl residue with 1 to 12 C atoms; and Y stands for CH2, CH(Me), CH(Et), C(Me)2, CH2—CH(Me), CH(Me)-CH2 or CH2—CH(Me)-CH2 and n stands for a whole number from 0 to 8, or Y stands for an optionally substituted phenyl or naphthyl ring with a total of at most four substituents on the ring, n=1 applying.
