Preparation of rhodium(III)-2-ethylhexanoate
The present invention provides a method for preparing rhodium (III) 2-ethylhexanoate solutions which supplies the reaction product with higher space yield, as well as lower sodium and chloride ion content. An aqueous solution of an alkali salt of 2-ethylhexanoate is thereby initially converted with a rhodium (III) precursor. The rhodium (III) precursor is selected from rhodium (III) chloride solution, rhodium (III) chloride hydrate, and rhodium (III) nitrate. The mixture is heated for several hours. After cooling to room temperature, the rhodium (III) 2-ethylhexanoate formed is extracted from the aqueous solution with an alcohol that is immiscible in water or a carboxylic acid that is immiscible in water, and optionally washed with aqueous mineral acid. The rhodium (III) 2-ethylhexanoate solution obtainable in this way may be used directly as catalyst in hydroformylation reactions.
Storing molecule within porous materials with a surface molecular barrier layer
In some aspects, the present disclosure provides compositions comprising a nanoporous material such as a metal organic framework and an amine containing compound. In some aspects, these compositions may be used to improve the affinity of a guest molecule to the nanoporous material relative a nanoporous material which had not been treated with the amine containing compound.
BIMETALLIC COORDINATION METAL-ORGANIC FRAMEWORK MATERIAL, PREPARING METHOD THEREOF, AND APPLICATION THEREOF
The present disclosure provides a bimetallic coordination metal-organic framework material, a preparing method thereof, and an application thereof. In the bimetallic coordination metal-organic framework material, carboxyl groups and soft groups of ligands are coordinated with coordination metal ions to assemble a structure having space and functions divided into covalent charge carrier layers and charge storage ion layers. Further, through the conjugation effect, the bimetallic coordination metal-organic framework material has unique electromagnetic properties, good electrical conductivity, and magnetic coupling performance. Thus, the bimetallic coordination metal-organic framework material is used as superconducting materials, conductive materials, semiconductor materials, or electromagnetic materials. Through the preparing method, the structure including the covalent charge carrier layers and the charge storage ion layers is assembled, so the bimetallic coordination metal-organic framework material has unique electromagnetic properties.
