Title:
PLATINUM GROUP METAL SUPPORTED CATALYST COLUMN AND METHOD FOR FORMING CARBON-CARBON BOND
Document Type and Number:
WIPO Patent Application WO/2022/219870
Kind Code:
A1
Abstract:
Provided is a platinum group metal supported catalyst column through which a reaction of forming a carbon-carbon bond in an aromatic bromide can be carried out at high yield. In the platinum group metal supported catalyst column, a platinum group metal supported catalyst is a catalyst in which at least one of platinum group metal nanoparticles, platinum group metal ions, and platinum group metal complex ions is supported on an ion exchanger, wherein the ion exchanger is composed of a continuous skeleton phase and a continuous pore phase, the thickness of the continuous skeleton is 1-100 μm, the average diameter of the continuous pore is 1-1000 μm, the total pore volume is 0.5-50 mL/g, the ion exchange capacity per weight in a dry state is 1-9 mg equivalent/g, and the ion exchanger is non-particulate organic porous ion exchanger in which the ion exchange groups are distributed in the ion exchanger, the amount of platinum group metal nanoparticles, etc., supported is 0.004-20 wt% in a dry state, and a platinum group metal scavenger is provided at the backward stage of the platinum group metal supported catalyst.
