| Abstract: | Process for preparing rich tran-chysanthemic acid (I) by isomerization and saponification of ethyl chrysanthemate has been studied.The product of isomerization, not being seperated, is directly saponified to achieved I.The factors on isomerization such as reaction temperature, time, amounts of sodium methoxide and ethyl glycol have been researched.The optiomal condition has been set. |
