    摘要: A method for the preparation of quasi-crystalline, porous inorganic and organic oxide materials possessing uniform framework-confined mesopores in the range 1 to 12 nm prepared using an organic silane, such as (RO)3SiR1. The method uses an interaction between various nonionic poly(oxyalkylene) polymer based surfactants and neutral inorganic oxide precursors at ambient reaction temperatures. Exemplary surfactants are alkyl-polyethylene oxides and alkylphenyl-polyethylene oxides. Exemplary inorganic oxide precursors are single metal and double metal alkoxides including tetraethylorthosilicate (TEOS). Recovery of the template can be achieved through solvent extraction where the solvent may be water, an organic solvent, a mixture of organic solvents, or a mixture of water and organic solvent(s). The porous products produced may be used as absorbents, ion-exchangers, catalyst, catalyst supports or composites.

    摘要: The invention relates to a catalyst for the epoxidation of alkenes using alkylhydroperoxide, the catalyst comprising an ion of one or more of the metals molybdenum, wolfram, titanium or vanadium on an inorganic carrier, characterised in that the metal ion is bound to the carrier via a polydentate organic ligand. The invention also relates to a process for the preparation of an alkene oxide by an alkene having 3 or more carbon atoms with an alkylhydroperoxide, using the catalyst described above.
