PROBLEM TO BE SOLVED: To provide a modified clay mineral that can be used for an olefin polymerization catalyst producing polyolefin with high productivity, and to provide an olefin polymerization catalyst using the mineral, and a production method of polyolefin using the polymerization catalyst. SOLUTION: The modified clay mineral is obtained by treating a clay mineral with an ionic compound having a cation that can be exchanged with interlayer cations of the clay mineral and with an ionic compound having an anion that can react with the surface of the clay mineral. The olefin polymerization catalyst comprises the modified clay mineral and a transition metal compound. COPYRIGHT: (C)2010,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a vitamin B 12 -modified core-shell type hyperbranched polymer and a dehalogenation catalyst. SOLUTION: Provided is a novel hybrid catalyst in which a highly branched polymer, a vitamin B 12 compound is immobilized on a core-shell type hyperbranched polymer through a covalent bond and the new hybrid catalyst has a high catalytic efficacy and a product selectivity different from conventional monomolecular catalysts. Also provided is a method which can easily recover and reuse the vitamin B 12 catalyst by immobilizing the vitamin B 12 compound on a polymer. COPYRIGHT: (C)2010,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a spherical catalyst having no restriction on kinds of a catalyst component to be carried, suppressing desorption of the catalyst component therefrom in use and capable of being easily separated and collected from reaction products or the like after its use. SOLUTION: The spherical catalyst comprises a spherical carrier primarily comprised of a thermoplastic resin and catalytically active microparticles deposited on the surface of the carrier.

Abstract:
PROBLEM TO BE SOLVED: To provide a capillary and a microreactor using the capillary, and to provide a solid phase/liquid phase/gas phase reaction method using the microreactor. SOLUTION: The microreactor 1 comprises: the capillary 2; a solution supply section 10 for supplying a solution 7 wherein a substrate is dissolved to the capillary 2 constituting the liquid phase; a gas supply section 20 for supplying gas 9 to the capillary 2 constituting the gas phase; and a recovery section 30 for recovering a reaction product in the capillary 2, wherein a catalyst 5 consisting of polysilane and a metal catalyst or consisting of polysilane, metal catalyst and metal oxide constituting the solid phase is deposited on the inner wall 3a of a pipe main body 3 of the capillary 2, and one end of the capillary 2 is connected to the solution supply section 10 and the gas supply section 20 and the other end is connected to the recovery section 30. The solution 7 wherein a substrate is dissolved and a gas 9 reactive with the substrate are controlled so as to continually flow into the capillaries 2 at a prescribed flow rate.
