“…The Mo-V-Nb is a versatile catalyst for the oxidative dehydrogenation. This catalyst mostly used in the oxidative dehydrogenation of ethane and propane [24,25]. The catalytic behaviour of this catalyst also investigated for the ammoxidation of propane to acrylonitrile [26][27][28].…”

In this paper, we report for the first time a one-pot reaction enabling total transformation of lactic acid to acetic acid over a Mo-V-Nb mixed oxide catalyst having an optimal atomic ratio 19:5:1. The mechanism of the reaction consists in two parallel ways leading to acetic acid: (i) oxi-dehydrogenation of lactic acid to pyruvic acid followed by decarboxylation and (ii) decarbonylation of lactic acid to acetaldehyde followed by oxidation. In the operating conditions we used, the catalyst is very active (total conversion of lactic acid) and selective towards acetic acid (100% selectivity). A 100% yield into acetic acid is hence obtained.

“…Other vanadiumbased catalysts were also studied by Tessier et al (1995) and Roy et al (1996) examined the influence of molybdenum. Numerous studies have been conducted on the oxidation of ethane to acetic acid to find other catalysts, as shown in several reviews (Ruth et al, 1998;Linke et al, 2002). Recently, a significant number of researchers have made great efforts to achieve the synthesis of acetic acid from ethane and carbon dioxide and oxygen (Smejkal et al, 2005;Linke et al, 2002).…”

-In this work, a series of perovskite-type mixed oxide LaMo x V 1−x O 3+δ powder catalysts (x = 0, 0.1, 0.3, 0.5, 0.7, 0.9, and 1.0, with 0.5 < δ < 1.5), prepared by the sol-gel process and calcined at 750°C, provide an attractive and effective alternative means of synthesizing materials with better control of morphology. Structures of resins obtained during the gel formation process by FT-IR spectroscopy and XRD analysis showed that all the LaMo x V 1-x O 3+δ samples are single phase perovskite-type solid solutions. The surface area (BET) between 2.5 -5.0 m 2 /g (x = 0.1 and 1.0 respectively) increases with increasing Mo ratio in the samples. They show high purity, good chemical homogeneity, and lower calcinations temperatures as compared with the solid-state chemistry route. SEM coupled to EDS and thermogravimetric analysis/differential thermal analyses (TGA/DTA) have been carried out in order to evaluate the homogeneity of the catalyst. Finally, the experimental studies show that the calcination temperature and Mo content exhibited a significant influence on catalytic activity. Among the LaMo x V 1-x O 3+δ samples, LaMo 0.7 V 0.3 O 4.2 showed the best catalytic activity for the topic reaction and the best activity and stability for ethane reforming at 850°C under 8 bar.
