Abstract:
A process for the preparation of an alkylene carbonate, said process comprising contacting the corresponding alkylene oxide with carbon dioxide in the presence of a metal salt immobilised on a solid support, wherein the metal salt comprises a cation of a metal selected from those in the third period and group 2, the fourth period and groups 2 and 4 to 12, the fifth period and groups 2, 4 to 7, 12 and 14, and the sixth period and groups 2 and 4 to 6 of the periodic table according to IUPAC nomenclature, and an anion selected from anions of inorganic acids and organic acids, and wherein the solid support contains a quaternary ammonium, a quaternary phosphonium, a quaternary arsenonium, a quaternary stibonium, or a ternary sulfonium cation.
Abstract:
PROBLEM TO BE SOLVED: To provide a metal oxide catalyst carrier allowing efficient decomposition and removal of VOC (Volatile Organic Compounds) generated inside an image forming device or the like during image formation in the device, by means of a metal oxide catalyst by use of ozone or light/heat, and to provide a method for producing the same.SOLUTION: This metal oxide catalyst carrier includes: porus silica; and the metal oxide catalyst at least incorporated in the porus silica, and comprising at least one kind selected from a group consisting of titanium oxide, zirconium oxide, cerium oxide and manganese oxide, and a specific surface area is 400 m/g or above.
