▎ 摘  要

NOVELTY - Asymmetric coordination catalyst comprises group (VIB) or (VIIIB) metal active components, the first ligand, a second ligand and carrier. The first ligand and the second ligand are different, and are respectively non-metallic ligands of Group (VA) or Group (VIA). The non-metal element of Group (VA) or Group (VIA) in second ligand is different from the non-metal element of Group (VA) or Group (VIA) in first ligand. The Group (VIB) or Group (VIIIB) metals include chromium (Cr), molybdenum (Mo), tungsten (W), iron (Fe), cobalt (Co), nickel (Ni), ruthenium (Ru), rhodium (Rh), osmium (Os), irridium (Ir), platinum (Pt) or palladium (Pd). The Group (VA) or Group (VIA) non-metallic ligands include nitrogen (N), phosphorus (P), arsenic (As), oxygen (O), sulfur (S), selenium (Se) or telurium (Te) elements. The non-metal of Group (VA) or Group (VIA) is N, P, O or S elements. The carrier is carbon carrier, preferably carbon nanofibers, carbon nanotubes, carbon nanosheets, graphene or carbon foam. USE - Asymmetric coordination catalyst used in the carbonylation reaction of catalyzed ethylenically unsaturated compounds (claimed). ADVANTAGE - The asymmetric coordination catalyst shows excellent activity and product selectivity, and when used for the carbonylation reaction of the olefinic unsaturated compound, the product selectivity is high, the catalyst is easy to separate, and the cost is reduced. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: 1. a preparation method of asymmetric coordination catalyst, which involves preprocessing the carrier, dissolving the active component precursor, the first ligand and the second ligand of Group (VIB) or Group (VIIIB) metal in an organic solvent, stirring and mixing uniformly, adding the pretreated carrier, heating to a certain temperature for reaction, and then washing and drying, and calcining the catalyst in an inert gas atmosphere; and 2. a process for the carbonylation of an ethylenically unsaturated compound, which involves reacting the ethylenically unsaturated compound with carbon monoxide and a hydroxyl-containing compound in the presence of the catalyst, where the molar ratio of the added amount of the hydroxyl-containing compound to the ethylenically unsaturated compound is 1:0.1-1:10, the molar ratio of the ethylenically unsaturated compound to carbon monoxide is preferably 1:1-10:1, the carbonylation reaction is carried out at 0-150℃, and carrying out reaction pressure at 0-10 megapascal.
