Innovative Synthesis in Continuous-Flow Processes for Sustainable Chemical Production

SYNFLOW

Subprogram: Module III - FP7

Name of PN II Program: Capacity

Goal: Innovative Ways for sustainable chemical production

Project summary

The SYNFLOW vision is the paradigm shift from batch-wise large volume processes in pharmaceuticals, fine chemicals and intermediates production comprising many separate unit operations towards highly integrated but yet flexible catalytic continuous flow processing. For this purpose, SYNFLOW develops a unique integrative approach combining molecular understanding of synthesis and catalysis with engineering science in process design and plant concepts, aiming at an efficiency breakthrough in process development and operation. The SYNFLOW mission is to overcome the traditional way of linear process development providing individual solutions for specific products, and to demonstrate the technological, economic and ecological superiority of truly „designing“ processes by application of advanced chemical and engineering knowledge. The SYNFLOW concept is based on the definition of generic challenges with industrial relevance, represented by Case Studies provided by the industrial consortium members. Catalyst development, studies of the underlying chemical target transformations (synthetic methodology), tailored reaction engineering, conceptual process design and process evaluation interact closely in order to substantiate the SYNFLOW vision. Its success will be demonstrated on a relevant production scale as a reference for the entire European Chemical Industry.

The obtained results

       Gold catalysts are an interesting alternative for VOC oxidation. In addition to oxidative catalytic reactions it was revealed that gold nanoparticles promote the catalytic activity of TiO2. It is remarkable that although gold is not a good catalyst in bulk or as large particles, if it is prepared as nanoparticles on oxide support is one of the most active catalysts.

       Catalysts such as 1% Au/TiO2 and Au of different supports were prepared, characterized and tested,. The method of preparation used was precipitation-deposition. Characterization of the catalysts was performed using a combination of techniques: DR-UV-Vis spectroscopy, DRIFT spectroscopy, Raman spectroscopy, Powder X-Ray Diffraction (PXRD). Catalytic tests showed that these catalysts are active.

Selection of the support and synthesis of the materials

The first step was the synthesis and selection of support. For this purpose, we synthesized MCM-41 and SBA-15, mesoporous supports while the other (titanium oxide, silica, alumina and carbon) were bougth from different companies:

-        Silica supports

-        Ttanium oxide supports

-        Carbon supports

-        Synthesis of Pt-Co colloids using acetylacetone metal complexes

-        Synthesis of Pt-Co colloids using metal chlorides

-        Synthesis of Pt-Co catalysts Supported by wet impregnation using metal acetylacetonate precursor complex

-        Synthesis of Pt-Co catalysts Supported by wet impregnation using metal nitrate precursors

Characterization of the catalysts

-          Textural properties of the supports

-          Textural properties of Pt-Co colloids prepared from acetylacetone metal complexes

-          Textural properties of Pt-Co colloids prepared from metal chlorides bear

-          Textural properties of Pt-Co prepared by impregnation using metal acetylacetonate complexes

-          Textural properties of Pt-Co prepared by impregnation using nitrate precursors

Direct amination

The coupling reaction between aniline and bromobenzene was investigated on heterogeneous catalysts containing 2wt% Pt-Co in order to identify the heterogeneous catalyst suitable for the reaction.

In this purpose, for each heterogenous catalyst was studied the influence of following parameters on the conversion and selectivity of aniline: (i) temperature between 120-200 ° C, (ii) reaction time from 1 to 44 h, (iii) the nature of the solvent (1, 4-dioxane or dimethylcarbonate), (iv) base loading (EtO-K+).
