Synthesis of 4-Biphenylbenzaldehyde
LI Hai-fengYANG Xi-zhiWANG Jun-feng Technology R&D InstitutionChemical Co. of Daqing OilfieldDaqing 163453China
AbstractCarbonization synthesis of 4-biphenylbenzaldehyde was made with biphenyl and carbon monoxide as raw material in the presence of Lewis acid catalyst. The structure of the product was characterized by infrared spectrumnuclear magnetic resonance and liquid chromatography. The effects of catalyst and reaction temperature upon the yield of 4-biphenylbenzaldehyde were being investigated. The optimal conditions were as followaluminium trichloride as main catalystcuprous chloride as help catalyst reaction temperature 15~50mass ratio of aluminium trichloride and biphenyl 1.3 1. The yield of 4-biphenylbenzaldehyde could reach 70% under the optimal condition.
