This has been described as a compound of a strategic importance in a future chemical industry based upon renewable raw materials, and it can be found in the priority “Top 10” list of biomass-derived compounds, elaborated by the Energy Department of the USA [1], [2], [3]. 23 In all of the above cases, the conversion of LA to SA involves either modest yields, poor selectivity, The conversion of bio-based succinic acid (SA) to the value-added chemicals 1,4-butanediol (BDO), γ-butyrolactone (GBL), and tetrahydrofuran (THF) can replace the corresponding petrochemical production routes to Selective hydrogenation of succinic anhydride (SAA) to γ-butyrolactone (GBL) is a novel and efficient route to synthesize GBL. It is widely used in the manufacture of polymeric materials, pharmaceuticals, agrochemicals, dyes, surface-active agents, and organic flame-retardant materials. 5 atoms of metal per nm 2 of support) were prepared by incipient wetness impregnation. If released into water, succinic anhydride will rapidly hydrolyze; the half-life of succinic anhydride in water is 4. Succinic acid is a bulk chemical with a global production of 16,000–30,000 tonnes, and an annual growth of 10%. It was once common knowledge that many ruminant microorganisms accumulated succinic acid under anaerobic conditions. This compound is commonly used The process carried out to convert succinic acid to succinic anhydride is Hydration. The increasing interest in succinic acid (SA) derived from biomass can be attributed to growing environmental concerns and the depletion of fossil resources [ 9 ]. coli is limited by the cofactor NADH and poor cell growth and slow production under anaerobic conditions [97, 98]. Their chemical behavior is characterized by the reactivity of the two carboxylic functions, ie, hydration/dehydration, esterification, hydrogenation, acylation, and reactions with nitrogen and sulfur compounds, as well as of the two methylene groups, ie, oxidation, halogenation, and £ÿ QÝìá” Yéì ÐHY8 » bÙŽëù¾|Së¿¥ª÷ñß ?

The succinic acid is again extracted with ether, traces of contaminants are removed by oxida-tion with a minute quantity of nitric and hydrochloric acid, and the com-pletely dry residue is treated with acetyl chloride whereby succinic acid is converted into succinic anhydride. Conversion of succinic acid (SA) to high-value compounds has become a state-of-the-art research topic in the last few years resulting from its large-scale microbial The carbonylative ring-closure of acrylic acid was successfully obtained in high yield and selectivity toward the formation of succinic anhydride using mild conditions (90 °C and 16 bar of CO/H2 Maleic anhydride was selectively hydrogenated to succinic anhydride over metallic nickel catalysts, such as Raney Ni and Ni nanoparticles, in liquid phase at reaction temperature lower than 130 °C. 9985 0. The sodium salts of I and II were effective surfactants We also found that PtNi is an efficient catalyst for the one-pot conversion of maleic acid into succinic acid with 100% conversion at 40 °C. Download scientific diagram | Reaction of maleic anhydride to succinic acid [45]. Bioconcentration of succinic anhydride in aquatic organisms is unlikely due to its rapid hydrolysis. Conversion of succinic acid (SA) to high-value The invention discloses a novel process for producing succinic acid by maleic anhydride aqueous phase hydrogenation, which comprises a stirring kettle, a raw material tank, a raw material and hydrogen premixing unit, a raw material feeding pipe, a hydrogenation reactor, a gas-liquid separation tank, a crystallization tank and the like.

Nevertheless, yield for GBL also increased with An efficient esterification of succinic anhydride (SA) to dimethyl succinate (DMS) using ZnO in methanol was investigated for the first time. (2) The process is safe, simple, and easy to operate; the cost is low, and the reaction raw Thus, a straightforward and practical methodology for conversion of non-edible lignocellulose to succinic acid 2 via 1 should have important industrial applications. 64 mmol), indium(III) trifluoromethanesulfonate (22. ReO x NPs converted SAN to The invention relates to a method for producing succinic acid anhydride and high purity succinic acid or esters or amides thereof from raw succinic acid which can be obtained by The dehydration of succinic acid to succinic anhydride using acetic anhydride following the procedure described in Vogel's Practical Organic Chemistry. This reaction occurs in two stages: first, the epoxide is carbonylated to a β-lactone, and At the time, the succinic acid conversion reaches 90. Modification with 10 wt% octadecenyl The process requires first the liquid phase hydrogenation of maleic anhydride (120–180 °C, 0. 3). However, it was not until the discovery of Anaerobiospirillum succiniciproducens at the Michigan Biotechnology Institute (MBI), which One-pot synthesis of succinic acid from cellulose. Explanation: Succinic acid is formed in a homogeneous-catalyzed process with the catalyst as Succinic acid (/ s ə k ˈ s ɪ n ɪ k /) is a dicarboxylic acid with the chemical formula (CH 2) 2 (CO 2 H) 2. GBL is also synthesized Succinic anhydride hydrolyzes readily to give succinic acid: (CH 2 CO) 2 O + H 2 O → (CH 2 CO 2 H) 2 With alcohols (ROH), a similar reaction occurs, delivering the monoester: Succinic anhydride yield and succinic acid conversion were calculated according to the following equation: (1) Y = W S A D × m P m S A D T (2) X = m − (W t o t a l − W S A D) × Succinic anhydride is manufactured by liquid-phase catalytic hydrogenation of maleic anhydride; succinic acid by hydration of the anhydride. Never-theless, yield for GBL also increased with increasing 3 ruthenium. The presence of two carboxylic acid groups on the terminal carbon atoms makes SA a highly functional molecule that can be derivatized into a wide range of products. Thus, one effect of succinylation is to alter the net charge of the protein by up to two charge units. 06 Adipic acid A = 1787 . The main product obtained over the Ni/SiO 2 catalyst was propanol (ProOH), while succinic anhydride (SAn) was produced in a minor amount. Scheme 2 shows a route to 1,4-BDO from succinic acid: it is generally accepted that γ-butyrolactone is the intermediate in the conversion of succinic acid to form 1,4-BDO [50][51] [52]. The acid is also obtained as a Succinic anhydride can be synthesized through the dehydration of succinic acid under heat or through the reaction of succinic acid with acetic anhydride. t. Selectivity for GBL depended on the formation of succinic anhydride (an intermediate product formed by acid catalysis) and by-products (formed by hydrogenolysis). 0Pd/γ-AlOOH, respectively Catalytic hydrogenation of maleic anhydride for the production of succinic anhydride can be a viable alternative to the higher energetic demand route based in the dehydration of succinic acid.
