    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.

    摘要： A process for removing metal species from a composition comprising contacting: a. an oligomer mixture stream comprising the monomers of a partially aromatic polyester polymer and at least one metal species, or b. a molten polyester polymer stream comprising partially aromatic polyester polymers and at least one metal species, with a non-catalytic porous material in the presence of hydrogen to produce a treated stream containing a reduced amount of at least one metal species. There are provided compositions comprising a partially aromatic polyester polymer having an It.V. of at least 0.50 produced in a direct esterification melt phase process, from greater than 0 to less than 50 ppm antimony, and less than 40 ppm cobalt, or produced in an ester exchange melt phase process, having from greater than zero to less than 5 ppm titanium and less than 10 ppm manganese.
