Vanadium catalyst composition and preparation method and application thereof

Abstract

A vanadium catalyst composition and a preparation method and application thereof. The vanadium catalyst composition is composed of a vanadium complex and an electron donor, the ligand of the vanadium complex is one of fatty alcohols, amines and phosphate esters, the electron donor is a sulfoxide compound, and the structural formula is R—S(═O)—R′, R is selected from one of C1-C3 alkyl, aryl, C1-C3 alkyl substituted aryl; R′ is selected from one of C1-C3 alky, aromatic alkyl. An electronic donor with oxidation property is adopted, an aqueous phase extraction method is combined, and a vanadium catalyst composition with a reactivation function is synthesized by a one-step method.
