Procedure: 1,2-dicyano-3-nitrobenzene (1.73 g) and 2-tert-butyl-cyclohexanol (4.68 g) were allowed to react with each other at 80° C. for 2 hours in dimethylformamide (DMF, 5 ml) with the addition of K2CO3 (5.0 g). After the completion of the reaction, the reaction product was extracted twice with a mixed solvent of water and ethyl acetate (at a volumetric ratio of 1/1), and the layer extracted with ethyl acetate was dried overnight with the use of MgSO4, followedby removal of ethyl acetate by distillation. The residues were isolated and purified by silica gel column chromatography using chloroform to obtain 1.41 g of 1,2-dicyano-2-(tert-butylcyclohexyloxy)benzene in a 50% yield. After the completion of the reaction the reaction product was extracted twice with a mixed solvent of water and ethyl acetate (at a volumetric ratio of 1/1), and the layer extracted with ethyl acetate was dried overnight with the use of MgSO4, followedby removal of ethyl acetate by distillation The residues were isolated purified by silica gel column chromatography

Procedure: In the autoclave, the resulting 453.6 grams of the 4 mole ethoxylate of 4-nonyl, 2-tert butylphenol was mixed with 125 grams of dioxane and 3.5 grams of the above-prepared catalyst and then the vessel was purged with nitrogen. Hydrogen was charged until the pressure reached 100 psi and then the autoclave was heated to 100° C. With moderate agitation the hydrogenation process continued until no more hydrogen was taken up. This reaction took approximately 4.5 hours. The product was recovered by filtering out the catalyst under nitrogen and then vacuum stripping off the volatile solvent. A water white liquid identified as 4-nonyl, 2-tert butylcyclohexyl alcohol with 4.0 moles of EO (NTBCH-4) was produced with less than 150 ppm of free 4-nonyl, 2-tert butylcyclohexyl alcohol and at least 81% saturation of the aromatic rings. the vessel was purged with nitrogen Hydrogen was charged until the pressure The product was recovered by filtering out the catalyst under nitrogen

Procedure: To a 300 ml round bottom flask provided with a Dimroth condenser and a dropping funnel, 7.5 g (0.194 mol) of sodium hydride (62 weight % mineral oil dispersion type) and 30 ml of tetrahydrofuran were added and heated at 60° C. under a nitrogen gas flow. Then, to this solution a mixture of 30.0 g (0.192 mol) of 2-tert-butylcyclohexanol (cis:trans=8:2) and 30 ml of tetrahydrofuran was added dropwise in approximately 30 minutes, and the mixed solution was stirred under reflux for 24 hours until the generation of hydrogen gas had stopped. The reacted mixed solution was cooled to 40° C., and after dropwise adding 11.1 g (0.192 mol) of propyleneoxide to the mixed solution, the solution was further stirred under reflux for 48 hours. The mixed solution was neutralized by 3N hydrochloric acid, and the organic layer was separated from the water layer. Distillation was then conducted and 9.9 g of 2-tert-butylcyclohexanol and 24.2 g of 1-(2-tert-butylcyclohexyloxy)-2-propanol (cis:trans=8:2) (bp. 112° to 113° C./5 mm Hg) were obtained in a 59% yield.
