Abstract In this paper,various syntheses of 2,3-dimethylpyrazine are reviewed,which raw materials includes from biacetyl and ethylene diamine,or from 2,3-butylene-glycol and ethylene diamine etc. Its application in medicine,pesticides, perfume and analytical chemistry also is described.Furthermore, we think the catalytic reaction in gas-solid phase is the superior developing trend and in this reaction,2,3-butylene-glycol should be replaced by cheap biacetyl.����
