The One

A novel method for synthesis of tricyclic benzimidazole derivatives by using continuous flow reactor is reported. Disadvantages of the well-known batch methods have been avoided utilizing the flow chemistry technology. Beside the one pot reductive cyclization using H-Cube Pro®, the dehydration step was also optimized producing the desired lactam compounds. Then the acylation was optimized under microwave conditions and that reaction was also integrated into the flow system using an Asia heater module. This acylation dramatically reduced the reaction time under continuous-flow conditions, with a residence time of 30 min.

This paper has aimed at evaluating the concentration of bioethanol obtained using sunflower stem as natural support, molasses as carbon source and Saccharomyces cerevisiae yeast in a continuous flow reactor. The natural support was tested to investigate the immobilization/growth of S. cerevisiae yeast. The concentration of bioethanol produced by fermentation was analyzed by gas chromatography using two methods: aqueous solutions and extraction in organic phase. The CO2 flow obtained during the fermentation process was considered to estimate when the yeast was deactivated. The laboratory experiments have highlighted that the use of plant-based wastes to bioconversion in ethanol could be a non-pollutant and sustainable alternative.
