摘要
A new process for the synthesis of zeolites and meso-porous solids based on Si, Al or Si+Al comprises: (1) synthesis of a homogeneous reaction mixt. of element(s) T (Si and/or Al) contg. 1 element(s) chosen from aq. basic- or alcohol solns. of alkyl tetra-orthosilicate and trialkoxy-aluminate; (2) heating the reaction mixt. to 20-220 degrees C for a few mins. to several hours; (3) injection, at a controlled rate, of 1 chemical agent, which generates poly-condensable species in the mixt.
