    • Abstract


      Kinetics of hydrogenation of some olefins such as 2,5-furandione,cis-butenedioic acid,trans-butenedioic acid,cis-methylbutenedioate andtrans-methylbutenedioate catalysed by anchored montmorillonitebipyridinepalladium(II) acetate have been studied in THF medium. The observed rate was found to be first order with respect to partial pressure of hydrogen and fractional order with respect to both [catalyst] and [substrate]. The rate of hydrogenation follows the trend: 2,5-furandione>cis-butenedioic acid>trans-butenedioic acid>cis-methylbutenedioate>trans-methylbutenedioate. Thermodynamic parameters were evaluated, the rate law and a probable mechanism have been proposed.
