Phase transfer catalysts polyethylene glycols immobilized onto metal oxide surfaces

Abstract Catalysts prepared by reacting polyethylene glycol and polyethylene glycol monomethyl ether with both alumina and silica gel were found to be effective phase transfer agents in displacement and oxidation reactions.

Micropore size distribution of octahedral molecular sieves (OMS)

Abstract Argon adsorption isotherms were used to study the micropore size distribution of manganese oxide octahedral molecular sieves, OMS-1 and OMS-2. Using the cylindrical pore model, this characterization tool provides accurate pore size information for OMS-1. However, this method is less accurate when measuring the smaller pore OMS-2. The argon adsorption isotherm measurement can be used to complement other standard characterization techniques to assess the quality of certain OMS products.
