A Novel Synthesis Route of Butyric Acid from Hydrogenation of Maleic Anhydride over Pd/TiO2 Catalysts

Abstract

A highly efficient Pd/TiO 2 catalyst for the liquid phase hydrogenation of maleic anhydride has been prepared by sol-gel method, and super critical fluid of ethanol drying (SCFE) was applied. The catalyst exhibited excellent activity and high yield to butyric acid. The structural properties of TiO 2 supported Pd catalyst were investigated by BET, TEM, XRD, XPS and TPR techniques with the aim of finding a correlation between the structure parameters and the catalytic activities.

Modeling of batch experimental kinetics and application to fed-batch fermentation of Clostridium tyrobutyricum for enhanced butyric acid production

“…Commercially available butyric acid is mostly produced by the oxidation of butyraldehyde which is made through the oxo-process where propylene, H 2 , and CO are reacted [2]. A novel synthesis method for butyric acid from maleic anhydride has also been reported [3,4]. However, there is a growing interest in the production of butyric acid from renewable resources by microbial fermentation due to increasing environmental concerns and the nature of limited fossil resources.…”

Liquid phase hydrogenation of maleic anhydride over nickel catalyst supported on ZrO2–SiO2 composite aerogels

“…Comparing with other reported liquid-phase MA hydrogenation systems [1][2][3][4][5][6][7][8][9][10], the advantage of this 30Ni/ZrO 2 -SiO 2 catalyst is that the GBL can be obtained with a high yield via a one-step continuous operation and no other by-products are formed besides the SA. And it could be proposed that nickel based catalyst supported on ZrO 2 -SiO 2 composite aerogels can be an effective one-step catalyst for hydrogenation of MA to GBL.…”

“…Jian Xu et al [7,8] Heondo Jeong et al [9] prepared a catalyst composed of palladium, molybdenum and nickel on a silica support of high surface area. This multi-component mixed metal oxide catalyst system in a batch-type reactor is found to be suitable for the hydrogenation of MA selectively to GBL.…”

Is selective hydrogenation of molecular oxygen to H2O2 affected by strong metal–support interactions on Pd/TiO2 catalysts? A case study using commercially available TiO2

“…This phenomenon has been reported for different hydrogenation reactions like hydrogenation of acetylene [3], of long chain alkadienes [6], of maleic anhydride [7] and of nitrate in water [8]. Despite a large body of literature concerning titania-based catalysis in the catalytic direct synthesis of H 2 O 2 (CDS) [9e13], the influence of the titania phase structure has not been systematically studied for this reaction.…”
