摘要： 以弱碱性苯乙烯系阴离子交换树脂[D392,—NH2,D382,—NHCH3,D301R,—NH(CH3)2],强碱性苯乙烯系阴离子交换树脂[201×7DVB,—NH+(CH3)3]和弱碱性环氧系阴离子交换树脂(701,—NH2)为载体制备了3种钯-高分子载体催化剂.考察了反应条件、高分子载体的种类、钯含量和催化剂用量对糠醛催化加氢生成四氢糠醇反应及催化性能的影响.在体积分数为50%的乙醇-水溶液和水中对糠醛常压液相加氢反应,钯-高分子载体(阴离子交换树脂D392,—NH2,D382,—NHCH3)催化剂均可使糠醛的加氢反应转化率达100%,生成四氢糠醇的选择性达98%以上,而用金属钯为催化剂的转化率达70%以上,选择性达97%以上.同时用XPS分析了高分子载体催化剂的结构与催化加氢反应性能的关系.

Abstract: Three kinds of polymer resin supported Pd catalysts were prepared by mixing PdCl2 with alkaline styrene anion exchange resins[D392 -NH2, D382, -NHCH3, D301R, -NH(CH3)2], strongly alkaline styrene anion exchanged resin[201×7DVB, -NH+(CH3)3] and alkaline epoxy exchange resin (701, -NH2), and hydrogenating in liquid phase at 1.013×105Pa. The hydrogenation of furfural was studied under the reaction conditions such as solvent, temperature, Pd content in the supported catalyst and the amount of the catalyst. The yield of hydrogenation reaction of furfural markedly increased to 100% and the selectivity to tetrahydrofurfuryl alcohol increased to over 98% by polymer(alkaline styrene anion exchange resins D392, -NH2, D382, -NHCH3) supported palladium catalysts comparing with the yield over 70% and selectivity over 97% by palladium catalyst, in 50% alcohol 50% water or pure water solution at 1013×105Pa. The relationship between hydrogenation and the structures of functional group in the supporting resin was examined by XPSmethod.
