摘    要: 介孔泡沫材料(MCF)是一种孔径有序,孔结构无序,稳定性高的新型纯硅基分子筛。MCF的开放式孔结构和可调变孔径使其适合于做催化剂的载体. 我们采用MCF为载体制备了PPh3-Rh/MCF催化剂,并应用于固定床中的丙烯氢甲酰化反应中(丙烯转化率21.6%,丁醛的时空收率160.6 mol醛/mol Rh·小时,正异比10.4).PPh3-Rh/MCF催化剂的稳定性远远高于HRh(CO)(PPh3)3/MCF催化剂.

关 键 词:三苯基膦    介孔泡沫材料  负载型催化剂  丙烯  氢甲酰化

Abstract:Siliceous mesostructured cellular foams (MCFs) are a new class of three-dimensional hydrothermally robust materials with ultralarge mesopores. The open system of large pores and the controllable pore size give MCFs unique advantages as catalyst supports. In this paper, MCFs were employed as supports in developing the PPh_3-Rh/MCF catalyst for propylene hydroformylation in a fixed-bed reactor. The PPh_3-Rh/MCF catalyst shows high activity (propylene conversion of 21.6% and butyraldehyde TOF of 160.6 h -1), high selectivity (n-butyraldehyde/i-butyraldehyde=10.4), and excellent stability under mild conditions of p=1.0 MPa, T=393 K, and SV= 2?000 h -1.
Keywords:triphenyl phosphine  rhodium  mesostructured cellular foam  supported catalyst  propylene  hydroformylation
