In　this　study,　the　baseline　separations　of　xylene　isomers　and　phthalate　acid　esters　on　a　homemade　DUT-67(Zr)　packed　column　were　achieved,　respectively.　The　high　selectivity　for　xylene　isomers　and　phthalate　acid　esters　was　obtained　with　the　increase　in　temperature　and　decrease　in　the　retention　time.　The　hydrophobicity　of　xylene　isomers　and　phthalate　acid　esters　resulted　in　the　different　separation　time　on　the　DUT-67(Zr)　packed　column.　The　relative　standard　deviation　values　of　retention　time,　peak　area,　peak　height,　and　half　peak　width　for　five　repeat　separation　of　the　xylene　isomers　were　0.26-0.35,　2.11-2.26,　1.51-2.03,　and　0.29-0.77%,　and　the　values　of　the　phthalate　acid　esters　on　DUT-67(Zr)　column　were　0.1-0.4,　4.4-5.2,　3.9-6.3,　and　0.6-2.1%,　respectively.　The　thermodynamic　properties　indicated　that　the　separation　of　xylene　isomers　was　controlled　by　Delta　H　and　Delta　S,　but　the　separation　of　phthalate　acid　esters　was　mainly　controlled　by　Delta　S.
