New catalyst could improve production of glass alternatives

22.08.2012
David Tyler's discovery could reduce waste made in the methyl methacrylate process

University of Oregon chemists have identified a catalyst that could dramatically reduce the amount of waste made in the production of methyl methacrylate, a monomer used in the large-scale manufacturing of lightweight, shatter-resistant alternatives to glass such as Plexiglas.

David Tyler, Charles J. and M. Monteith Jacobs Professor of Chemistry, presented his findings Tuesday, Aug. 21, at the national meeting of the American Chemical Society in Philadelphia.

Global production of methyl methacrylate was 4 million metric tons in 2010. Each kilogram produced also yields 2.5 kilograms of ammonium hydrogen sulfate, a corrosive byproduct that is not usable. Disposal of ammonium hydrogen sulfate is extremely energy intensive, consuming 2 percent of the energy used in Texas annually.

Tyler's team has identified a catalyst that doesn't produce ammonium hydrogen sulfate.

"There were some really fundamental chemical reasons why previous catalysts didn't work with this process," Tyler said. "We've found a catalyst that overcomes all of those objections."

With the identification of a working catalyst, Tyler will focus his research on how to accelerate the conversion to methyl methacrylate. The industrial standard for a practical catalyst is conversion of acetone cyanohydrin into methyl methacrylate in the span of a minute or two, Tyler said.

About the University of Oregon

The University of Oregon is among the 108 institutions chosen from 4,633 U.S. universities for top-tier designation of "Very High Research Activity" in the 2010 Carnegie Classification of Institutions of Higher Education.

Im Focus: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Im Focus: Three Magnetic States for Each Hole

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".

Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
