Embodiment 1

[0024] Using the known production process of styrene-based cation exchange resin, such as D001 resin production process, the difference is that 5% of copper acrylate is added to the polymerized monomer, and 0.5% of tetrafluoroethylene participates in polymerization to obtain styrene-based cation exchange resin. Cation exchange resin, boiled with pure water until colorless, to remove free acid inside the resin.

[0025] Put 100g of resin into the reaction kettle, add water with 60% of the resin weight, stir evenly, raise the temperature to 20°C, quickly add 100g of palladium chloride solution with 1% palladium ion weight concentration, stir and react for 2.5 hours, remove the reaction residue , cooling and discharging, to obtain the palladium-loaded resin catalyst. Sample number K01.

Embodiment 2

[0027] Add copper acrylate that accounts for 1% of the monomer percentage content in the polymerization monomer, other steps are identical with embodiment 1, sample number K02.

Embodiment 3

[0029] Add copper acrylate that accounts for 10% of the monomer percentage content in the polymerization monomer, other steps are identical with embodiment 1, sample number K03.

Abstract

The invention discloses a preparation method for a palladium supported resin catalyst. The preparation method comprises the following steps of: introducing cupric ions and fluoride ions into a main chain of a styrene series cation exchange resin polymer, and then carrying out a palladium supported treatment process. The palladium supported resin catalyst prepared by the invention has the advantages that the palladium supporting effect is good, palladium is not easy to remove, the low-temperature activity is high, the strength is higher, and the service life is long.

Description

technical field [0001] The invention relates to a preparation process of an ion exchange resin, in particular to a preparation process of a palladium-loaded resin catalyst. technical background [0002] There are some publications on the technology of developing ion exchange resin supported palladium catalyst at home and abroad, such as GB1010260, the disclosed palladium / strongly acidic ion exchange resin catalyst of US3953517 uses palladium nitrate to impregnate strongly acidic ion exchange resin, and this resin catalyst is a synthetic methyl isobutyl ketone The main catalyzer, but catalytic activity is lower, selectivity is lower; CN1457927 has announced a kind of palladium / strongly acidic ion exchange resin catalyst, adopts the acidic solution containing palladium and strongly acidic ion exchange resin catalyst to carry out ion exchange; CN1883793 has announced a A nano-palladium catalyst and a preparation method thereof are polymer-supported nano-palladium catalysts obta...
