A method of synthesizing 2-picoline using ethyne and acetonitrile as materials was discussed in this paper .Optimal conditions of the synthesizing 2-picoline were decided by the cross test design . The optimal conditions were that the reaction temperature was 180℃ ,the ethyne pressure was 1 . 2MPa ,the reaction time was 16h ,and the dosage of the catalyst was 200mg in proper order .The result of experiments show s that the catalyst and the solution of separated 2-picoline can be used in the progress in the optimal conditions .The mean yield of 2-picoline was higher than 77% and the content of 2-picoline rectified was higher than 99 .5% .
