NOVEL NANOPOROUS ORGANIC POLYMER COMPOSITE USEFUL AS CATALYST COMPRISING MESOPOROUS SILICA OR CARBON MOLECULAR SIEVE AND ORGANIC POLYMER SUPPORTED IN THE MICROPORE OF THE MOLECULAR SIEVE, AND ITS PREPARATION METHOD

摘要

PURPOSE: Provided are a novel nanoporous organic polymer composite which is improved in structural regularity, mechanical strength, thermal stability and chemical resistance, and its preparation method. CONSTITUTION: The nanoporous organic polymer composite comprises a mesoporous silica or carbon molecular sieve provided with a micropore with a size of 2-50 n m in the mesopore wall; and an organic polymer which is supported in the micropore of the molecular sieve and is coated to the wall face of the molecular sieve. Preferably the amount of the organic polymer is 1-100 wt% based on the weight of the mesoporous molecular sieve. Preferably an organic functional group is introduced into the nanopore wall of the molecular sieve. The composite is used as a porous catalyst in the acid-based catalyst reaction such as esterification, alkylation, Knoevenagel reaction, aldol condensation reaction, isomerization, etc. and the oxidation-reduction reaction such as benzene-alcohol oxidation reaction, etc.
