摘要：NOVELTY - Amino chromium pyridine complex (I) is new. USE - Amino chromium pyridine complex (I) used as main catalyst for catalytic alkylation reaction of olefin, preferably ethylene and aromatic hydrocarbon compound, preferably toluene (all claimed). ADVANTAGE - The amino chromium pyridine complex (I) realizes catalytic alkylation reaction under mild condition with low ethylene pressure, has easy to obtain raw materials, simple preparation, high product yield, stable property, high catalytic efficiency, and little environmental pollution compared with zeolite catalyst, and is used at little amount. DETAILED DESCRIPTION - Amino chromium pyridine complex of formula (I) is new. R1, R2=H, 1-10C linear, branched or cyclic alkyl, 7-20C mono or polysubstituted aryl alkyl group. INDEPENDENT CLAIMS are included for: (1) preparation of amino chromium pyridine complex (I); and (2) use of amino chromium pyridine complex of formula (I) as catalyst for catalytic alkylation reaction of olefin and aromatic hydrocarbon compound.
