Scientists managed to synthesize a kind of new nanocatalyst which has higher reaction rates than similar catalysts in epoxide production processes.

Scientists Synthesize New Nanocatalyst for Epoxide Reactions

Iran | Posted on April 15th, 2010

This accomplishment done by researchers at Zanjan University, Iran, in cooperation with colleagues from Freiburg University, Germany, opens doors for the catalytic synthesis of highly pure laboratory organic materials.

"The aim of the research was to synthesize a new brand of catalysts capable of converting organic alkene compounds to epoxide at higher rates and selectivities," Hassan Hosseinimonfared, professor of mineral chemistry at Zanjan University, said to the Iran Nanotechnology Initiative Council.

The results revealed that the synthesized catalyst possesses good activity for epoxidation of cyclooctene and cyclohexene with conversion percent more than 64% while aryl- derivatives of alkenes have low efficiency. One of the remarkable features of the mentioned catalysts at nanoscale is their high activity over bulk catalysts.

These catalysts confine decomposition of oxygenated water which is a common property of most of manganese II compounds and are also less costly and simpler than other catalysts.

First in the research project, Hosseinimonfared synthesized coordination polymers of manganese. Then, he synthesized Mn(II) dicarboxylate-terephthalic acid coordination polymer out of the mentioned polymer by ultrasound method at both bulk and nano scales due to its high catalytic activity and detected it by DGA, TGA, SEM, XRD, and IR methods.

"The catalytic activity of Mn(II) dicarboxylate-terephthalic acid with dielectric constant, dipole moment, and solvent boiling point (which is maximum for acetonitrile) increased through this method. It is notable that Mn(II) dicarboxylate-terephthalic acid coordination polymer catalyst could be used for the production of epoxide and other organic compounds," he said, elaborating on the results of this study.
