Douglas Raynie: Are Green Separations Possible?

Douglas Raynie

Department of Chemistry and Biochemistry
South Dakota University

Abstract:

As the concept of green chemistry is establishing itself throughout chemical laboratories, its adoption is moving into analytical laboratories, often with little understanding of what green chemistry is. The solvents used for separations are typically the largest source of waste in an analytical procedure. But waste minimization is not enough. Energy, toxicity, safety and other concerns are also important. During this presentation, the concept of green chemistry will be introduced and discussed relative to the separations process. Solvent considerations will be presented and a means of assessing analytical methods relative to green criteria developed. Finally, separations using a new class of solvents, deep eutectics, for analytical separations will be introduced. Physical properties of deep eutectic solvents important to separations will be discussed and applications in the dissolution and separation of biomass compounds will be shown.

About the Speaker:

Dr. Doug Raynie is a Research Associate Professor in the Department of Chemistry and Biochemistry at South Dakota State University. Prior to joining SDSU, he was employed for eleven years as a Senior Scientist at Procter and Gamble's Corporate Research Division. He earned his Ph.D. at Brigham Young University under the direction of Dr. Milton L. Lee. His undergraduate degree is from Augustana (South Dakota) College, with majors in chemistry and biology. Dr. Raynie’s broad research interests are in the field of sustainability and green chemistry. His two major areas of research are bioprocessing using supercritical fluids and related technologies and analytical separations. Analytical separations research includes high-resolution chromatography (high-temperature LC and SFC), chromatographic sample preparation (ASE, SFE, SPME, and SPE), chromatography theory, green analytical chemistry, and problem-based learning in analytical chemistry. In addition to several publications and presentations inthese areas, he has taught short courses covering ASE, SFE, SPME, sample preparation, green chemistry, and analytical problem-solving, and served on the editorial advisory boards of Pharmaceutical Formulation and Quality, the Journal of Microcolumn Separations and the Encyclopedia of Separation Science.
