Elsevier, Guo H, Yin G (2011) Catalytic aerobic oxidation of renewable furfural with phosphomolybdic acid catalyst: an alternative route to maleic acid. [33, 46] have studied oxidation of furfural with H2O2 to succinic acid (SA) on acid catalysts. In the most plausible pathway, the furfural radical generates the furfural cation intermediate, which is then attacked by a H2O molecule to form the intermediate 4-hydroxyfurfural. The formation of CO2 in vapor phase oxidation of furfural to maleic anhydride could originate from both direct oxidation of furfural or successive oxidation of maleic anhydride. Reactions. Terms and Conditions, Full Article. Synthesis of PEO-b-Poly(maleic acid). High conversions of furfural and good selectivity to succinic acid were reported (74%). This trend was explained by the low solubility of FA in water, which then converts to a highly soluble MA via isomerization. Hydrogen peroxide (H2O2) was then loaded to realize the oxidation of furfural without the separation of intermediates. Possible mechanism of 5-hydroxymethylfurfural (HMF) oxidation with O2 in liquid phase. The same authors claimed that furan is not the intermediate in the maleic anhydride formation over the H5PV2Mo10O40 catalyst in the liquid phase [44].

Maleic acid was commercially available in 1928 and fumaric acid production began in 1932 using an acid-catalyzed isomerization of maleic acid process. Moreover, taking into account that furfural oxidation to maleic anhydride differs from zero-order kinetics towards O2, it implies a different reaction pathway compared to the Mars–van-Krevelen mechanism. However, in some cases, relatively good selectivity to MA was also observed (up to 16% in the case of Amberlyst-15 catalyst).

This radical can be transformed to furfural cation (via electron transfer to the catalyst) and further react with water to generate an intermediate compound easily oxidized to maleic acid [30]. by caustic soda, to obtain the acid salt bi-decanylmalèiat ethyl which is soluble in water. They showed that the aldehyde group of HMF was relatively stable under oxygen atmosphere, and that MA was probably not formed via a decarboxylation reaction.

New Applications for . Antoine Lavoisier in 1787 proposed the name acide malique, which is derived from the Latin word for apple, mālum—as is its genus name Malus. Reaction pathways proposed for the selective oxidation of furfural to furan and maleic anhydride over VOx/Al2O3 catalysts [40]. Murthy compared three possible reactions schemes over vanadium pentoxide catalysts: parallel consecutive mechanism (parallel formation of CO2 from furfural and maleic anhydride), parallel reaction (CO2 originating from maleic anhydride is negligible) and consecutive mechanism (CO2 formation from furfural is negligible). [44] proposed that the formation of maleic anhydride could be initiated from the furfural radical intermediate formed after the first hydrogen abstraction by oxygen. Meanwhile, there is still no consensus on the role of the nature of the active phase and on the mechanism of the reaction. This paper is based on the most recent publications, and we put emphasis on the factors that have to be considered to understand the catalytic activity of the nanomaterials in maleic … Shimanskaya et al. In this mechanism, the first hydrogen atom is abstracted by the oxygen or catalyst and results in the furfural radical formation. Indeed, polyvanadates exhibited the highest normalized rate as compared to monovanadates and V2O5, which showed similar activities. Fine Chem Mumbai, India and Loba Chemie respectively. Synthesis of an ester based on maleic anhydride: The characteris The ester based on maleic anhydride which belongs to the family of Thereafter, a decrease in the FA yield concomitantly with an increase in the MA yield was observed. NO. MDL number MFCD00063177. Moreover, they found that increasing O2 pressure exhibited a positive effect on furfural conversion. The oxidation can be carried out in gas or liquid phase. Maleic acid CAS 110-16-7. Google Patents, Harry O, Mitchell B, Russell JL (1964) Preparation of fumaric acid by catalytically isomerizing maleic acid produced by the oxidation of butene-2. Moreover, as expected, the mechanism of maleic anhydride formation in the liquid phase is different from that observed in gas phase oxidation of furfural. In the oxidation of furfural to maleic acid, one atom of carbon must be removed. The current data reveal that, using dioxygen as oxidant, the simple copper salts can catalyze oxidation of furfural to maleic acid in aqueous solution.

The presence of various active species should then be related to different catalytic activities. The catalytic behavior of the catalysts was evaluated in a continuous fixed-bed reactor, using a feeding stream comprising 2% furfural in air at 578 K. The authors found that the activity depends on the MoO3/V2O5 ratio. However, there is still no consensus on the exact mechanism of the reaction and the role of the nature of the active phase.

This enables the rapid exchange of crystal lattice oxygen in the catalysts and then accelerates the overall activity and improves the selectivity to maleic anhydride [41]. Maleic anhydride can be commercially produced by the vapor-phase oxidation of benzene or butene/butane using O 2 as an oxidant [ 10 – 15 ]. The oxidation of furan in the presence of vanadium (V) oxide takes place through a route involving the formation of an endoperoxide, [43] which is then oxidized to maleic anhydride, as described below (Scheme 3).
