    摘要: Disclosed is a process for the preparation of a 2,2,4,4-tetraalkylcyclobutane-1,3-diols by hydrogenation of a 2,2,4,4-tetraalkylcyclobutane-1,3-dione in the presence of a catalyst comprising ruthenium deposited on a carbon nanotube support. The process is useful for the preparation of 2,2,4,4-tetramethylcyclobutane-1,3-diol. The process may be carried out in the presence or absence of a solvent and in the liquid or vapor phase. Also disclosed is a process for modifying the cis:trans ratio of the 2,2,4,4-tetramethylcyclo-butane-1,3-diol hydrogenation product by contacting the diol with hydrogen in the presence of a supported ruthenium catalyst.
