摘　　要：The mixture containing trans and cis former of 4-（trans-4’-n-propylcyclohexyl）cyclohexanol was prepared by hydrogenation of 4-（trans-4’-n-propylcyclohexyl）phenol with ruthenium/carbon catalysts.Isomerization reaction was performed at 200℃ without separating catalysts,the mass ratio of trans former to cis former was 71.1:28.9,the yield of trans-4-（trans-4’-n-propylcyclohexyl）cyclohexanol was 56.3%.The product was characterized by IR,MS,DSC and13C NMR.The possible reaction mechanism was also dicussed.The mixture containing trans and cis former of 4-(trans-4'-n-propylcyclohexyl)cyclohexanol was prepared by hydrogenation of 4-(trans-4'-n-propylcyclohexyl)phenol with ruthenium/carbon catalysts.Isomerization reaction was performed at 200℃ without separating catalysts,the mass ratio of trans former to cis former was 71.1:28.9,the yield of trans-4-(trans-4'-n-propylcyclohexyl)cyclohexanol was 56.3%.The product was characterized by IR,MS,DSC and^(13)C NMR.The possible reaction mechanism was also dicussed.
