Green analytical chemistry processes aim at minimizing the effects of pollution agents in the human health and nature through the design of new processes or new tools. One of the main trends to achieve this objective is the introduction of new technology based on miniaturized methods that allow for a reducing of reagents and/or materials, on the one hand, and that also permit the gathering of information necessary in the transition from laboratory- to production-scale, on the other. In this presentation, we will focus on microreactor technology (in particular, packed-bed microreactors) as a tool for investigating complex catalytic reactions. Modern approaches for the characterization of the kinetics and the thermodynamics of the catalytic processes in flow-mode will be discussed through the study of slow and fast model reactions. Technical and instrumental expedients as means for process optimization and automation will be presented with particular emphasis to the preparation of new catalytic supports through green organic chemistry strategies.

Abstract
Green analytical chemistry processes aim at minimizing the effects of pollution agents in the human health and nature through the design of new processes or new tools. One of the main trends to achieve this objective is the introduction of new technology based on miniaturized methods that allow for a reducing of reagents and/or materials, on the one hand, and that also permit the gathering of information necessary in the transition from laboratory- to production-scale, on the other. In this presentation, we will focus on microreactor technology (in particular, packed-bed microreactors) as a tool for investigating complex catalytic reactions. Modern approaches for the characterization of the kinetics and the thermodynamics of the catalytic processes in flow-mode will be discussed through the study of slow and fast model reactions. Technical and instrumental expedients as means for process optimization and automation will be presented with particular emphasis to the preparation of new catalytic supports through green organic chemistry strategies.I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
