Abstract :
Disproportionate rosin (DPR) is a mixture of
rosin acids with dehydro-abietic acid as its major component.
Alkaline salts of DPR are used as emulsifier surfactant
in emulsion polymerization reactions. In this work,
synthesis of DPR by the use of palladium nanoparticles
loaded on activated carbon was studied. The nanocatalyst
was characterized by TEM, SEM, XRD, N2 adsorption–
desorption and AAS. The reusability of the prepared
nanocatalyst was successfully examined three times with
only a very slight loss of catalytic activity.
