摘　　要：讨论了共轭亚油酸几何异构体的形成机制,通过半经验量子化学方法AM1计算了9c,11cCLA到9c,11tCLA扭转二面角与生成热之间的关系.指出前驱物中9,12位非共轭双键的构型、反应温度、反应时间决定了产物中CLA的各种几何异构体的含量.Formative mechanism of geometrical isomers of conjugated linoleic acid is discussed in the paper. The relationship between twist degree of dihedral angel and heat of formation from 9c,11c CLA to 9c,11t CLA is calculated through semiempirical quantum chemistry method AM 1. The paper indicates the precursor's geometrical configuration of nonconjugated double bonds in 9 and 12 carbon atom combining with reaction temperature and time are main reasons which determine the content of different geometrical isomers in target product.
