| Abstract: | Conjugated linolenic acids were prepared by alkali isomerization using linseed oil as raw material,KOH as catalyst,and glycerol as solvent.The products were characterized by gas chromatography,FT-IR,UV absorption spectra and GC-MS.The maximum yield of 74.5% was obtained when alkali/oil ratio was 1.0 and solvent/oil ratio was 10 at 180 ℃ for 120 min. |
