Definitions
- the invention relates to a process for the preparation of cis-2-tertiary butylcyclohexanol from 2-tertiary butylphenol, the cis isomer preferably being formed under the hydrogenation conditions.
- 2-tertiary-butylcyclohexanol which can occur in the form of the ice and trans stereoisomers, is a valuable intermediate for the production of the fragrance 2-tertiary-butylcylohexyl acetate.
- the aim is to obtain large proportions of the cis isomer in order to subsequently obtain the perfume-worthy ice-2-tertiary-butylcyclohexyl acetate, which is marketed under the common name Agrumex HC is known.
- noble metal catalysts such as metallic rhodium, rhodium-platinum and rhodium-ruthenium alloys are known which are deposited on catalyst supports.
- JP-A 42-13 938 A disadvantage of the hydrogenation in the presence of a rhodium catalyst is, in addition to the high price for the catalyst, the low stereoselectivity with regard to the cis isomer and the decrease in activity of the catalyst at higher temperatures. In addition, tertiary-butylbenzene is formed in the rhodium-catalyzed hydrogenation.
- a 3401343 describes the hydrogenation of 2-tertiary-butylphenol to 2-tertiary-butylcyclohexanol in the presence of palladium and ruthenium, where work in two stages at hydrogen pressures above 200 bar and temperatures of 70 ° -200 ° C.
- a palladium catalyst is used in the first stage and a ruthenium catalyst is used in the second stage.
- the cis / trans ratio is up to 90/10.
- JP A 59/065031 describes the hydrogenation of 2-tertiary-butylphenol to 2-tertiary-butylcyclohexanol under Raney cobalt catalysis at 50 bar and 150 ° C., the cis: trans isomer mixture being formed in a ratio of 94: 6 ,
- JP A 49/045037 describes the hydrogenation of 2-tertiary-butylphenol to 2-tertiary-butylcyclohexanol under Raney nickel catalysis at 80 bar and 85 ° C.
- the Raney nickel catalyst is treated with aqueous sodium boranate solution before use. With this catalyst treated in this way, the cis: trans isomer mixture is formed in a ratio of 92: 8. Without treatment of the Raney nickel catalyst, the cis: trans isomer mixture is formed in a ratio of 80:20.
- the object of the present invention is accordingly to provide a process which provides inexpensive 2-tert-butylcyclohexanol with a high cis isomer content and guarantees an extended service life of the catalyst compared to the prior art.
- Raney nickel-iron catalysts is particularly preferred.
- Butylcyclohexyl acetate leads to a 2-tertiary-butylcyclohexanol with a cis-trans isomer mixture of up to 95: 5.
- the catalyst can be used in the dry or moist state for the process according to the invention.
- the proportion of iron in the dry catalyst can be 2-40% by weight, preferably 10-20% by weight; the proportion of nickel 60-95% by weight, preferably 70-85% by weight, the proportion of aluminum 1-20% by weight, preferably 3-10
- the weight ratio of the catalyst used to 2-tertiary-butylphenol is 0.0001 to 0.1, preferably 0.01 to 0.03 to 1.
- the weight ratio of the starting materials 2-tertiary-butylphenol and 2-tertiary butylcyclohexyl acetate can be 100-0.2: 1, preferably 7-9: 1.
- the reaction temperature for the process according to the invention is 50 to 200 ° C., preferably 90 to 130 ° C.
- the hydrogen pressure is 1 to 100 bar, preferably 10 to 20 bar.
- the reaction time is 2 to 100 hours, preferably 5 to 20 hours.
- the raw mixture has the following composition:
- the ratio of cis-trans 2-tertiary butylcyclohexanol is 95: 5.
- the subsequent batches 2-13 proceed analogously to 1, the catalyst from the starting batch 1 being reused.
- the cis-trans ratio varies between 94: 6 and 91: 9.
