“…The alternative reaction pathway associated with the direct dehydration to yield 5-MF (k3 and k4) were significantly slower than the main reaction pathway with <0.1 min −1 and 0.2 min −1 , respectively. Due to the moderately high bond dissociation energies of the C-OH group to be around 280 kJ mol -1 , it seems logical that the direct dehydration to 5-MF while keeping the aldehyde group intact would not readily occur [86] [87]. The side reaction involving the formation of humins (k8) was also quite slow with 1.4 min −1 , although was not insignificant with a final product selectivity of 7% at 230 °C (Figure 9e).…”

“…However, the high complexity of this renewable raw material and especially the high mass fraction of oxygen in comparison to fossil carbon resources is limiting its widespread utilization. Decarboxylation is an important method for defunctionalization, which can be employed to alleviate these impediments [1][2][3][4][5].…”

Carrier-free enzyme immobilization techniques are an important development in the field of efficient and streamlined continuous synthetic processes using microreactors. Here, the use of monolithic, self-assembling all-enzyme hydrogels is expanded to phenolic acid decarboxylases. This provides access to the continuous flow production of p-hydroxystyrene from p-coumaric acid for more than 10 h with conversions ≥98% and space time yields of 57.7 g·(d·L)−1. Furthermore, modulation of the degree of crosslinking in the hydrogels resulted in a defined variation of the rheological behavior in terms of elasticity and mesh size of the corresponding materials. This work is addressing the demand of sustainable strategies for defunctionalization of renewable feedstocks.

Article history Characterization and catalytic activity of modified natural zeolite for the conversion of citronella oil to menthol was investigated. In this research, natural zeolite was prepared by acid activation with HCl and impregnated with Ni metal. The addition of Ni metal of around 12.5 nm in diameter provided a bifunctional catalyst for two steps of citronella oil crude conversion i.e. cyclization and hydrogenation. The process was performed in a one-pot reaction system by stirring at 200 o C with pressure of 20 bar H2 for 3h. The reaction products changed slightly with varieties of reaction temperature and amount of catalysts employed. Results showed that Ni/NZB-HT catalyst was the best catalyst which was able to convert citronella oil to menthol with a selectivity of 50% menthol and 100% conversion of citronellal.
