3,5,6-Trichloropyridin-2-ol(TCPO)was synthesized using trichloroactyl chloride and acrylonitrile as raw materials,nitrobenzene and A as solvent and B and CuCl as catalyst.When n(trichloroactyl chloride)∶n(acrylonitrile)was 1.4∶1,V(nitrobenzene)∶V(compound A)was 3.5∶1, m(CuCl)∶m(B)was 1∶0.15 and reaction time was 12 h, the yield and purity of product were 71% and 97.9% respectively. The structures of products and main impurities were confirmed by FT-IR and GC-MS.
