Occurrence
Has apparently not been reported to occur in nature.
Verwenden
4-tert-Butylcyclohexanone is used as a perfuming agents and in cosmetic. This material, commercially available for almost two decades, has only temporarily gained some importance as a powerful, “lifting” soap perfume ingredient, or as an in-expensive additive to Patchouli notes for soap and detergent fragrances, etc. It has more power and much less tenacity than Cedarwood and Patchouli, which is only an advantage in certain types of household products, where tenacity is not always very desirable. The title ketone can also give powerful “lift” to certain types of floral fragrance and to most of the herbaceous ones, Lavender, Lavandin, Rosemary, etc.
synthetische
By hydrogenation of p-ferr-butylphenol. Care must be taken that no free p-tert-butylphenol remains, because it is a sensitizer and depigmenting agent(Opdyke, 1974).
läuterung methode
Purify it via the semicarbazone (crystallised from EtOH with m 203-205o), hydrolyse this with dilute HCl and steam distil it. The distillate is extracted into Et2O, dried, evaporated and the residue is recrystallised from pentane, aqueous EtOH or EtOH [Houlihan J Org Chem 27 3860 1962]. The oxime recrystallises from 1,2-dichloropropane and has m 137.5-138.5o. [Harvill et al. J Org Chem 15 58 1950, Beilstein 7 IV 82.]
