[Reactivity Profile]

FUMARIC ACID(110-17-8) is a carboxylic acid. Carboxylic acids donate hydrogen ions if a base is present to accept them. They react in this way with all bases, both organic (for example, the amines) and inorganic. Their reactions with bases, called "neutralizations", are accompanied by the evolution of substantial amounts of heat. Neutralization between an acid and a base produces water plus a salt. Carboxylic acids with six or fewer carbon atoms are freely or moderately soluble in water; those with more than six carbons are slightly soluble in water. Soluble carboxylic acid dissociate to an extent in water to yield hydrogen ions. The pH of solutions of carboxylic acids is therefore less than 7.0. Many insoluble carboxylic acids react rapidly with aqueous solutions containing a chemical base and dissolve as the neutralization generates a soluble salt. Carboxylic acids in aqueous solution and liquid or molten carboxylic acids can react with active metals to form gaseous hydrogen and a metal salt. Such reactions occur in principle for solid carboxylic acids as well, but are slow if the solid acid remains dry. Even "insoluble" carboxylic acids may absorb enough water from the air and dissolve sufficiently in FUMARIC ACID(110-17-8) to corrode or dissolve iron, steel, and aluminum parts and containers. Carboxylic acids, like other acids, react with cyanide salts to generate gaseous hydrogen cyanide. The reaction is slower for dry, solid carboxylic acids. Insoluble carboxylic acids react with solutions of cyanides to cause the release of gaseous hydrogen cyanide. Flammable and/or toxic gases and heat are generated by the reaction of carboxylic acids with diazo compounds, dithiocarbamates, isocyanates, mercaptans, nitrides, and sulfides. Carboxylic acids, especially in aqueous solution, also react with sulfites, nitrites, thiosulfates (to give H2S and SO3), dithionites (SO2), to generate flammable and/or toxic gases and heat. Their reaction with carbonates and bicarbonates generates a harmless gas (carbon dioxide) but still heat. Like other organic compounds, carboxylic acids can be oxidized by strong oxidizing agents and reduced by strong reducing agents. These reactions generate heat. A wide variety of products is possible. Like other acids, carboxylic acids may initiate polymerization reactions; like other acids, they often catalyze (increase the rate of) chemical reactions. Partial carbonization and formation of maleic anhydride occur at 446° F (open vessel).

Questions and Answers (Q&A)Back Directory

Fumaric acid is an important kind of organic chemical raw materials as well as the intermediate of fine chemical products. Meanwhile, it is also an important kind of derivatives of maleic anhydride, being widely used in food, coatings, resins and plasticizers. In the food industry, fumaric acid, used as souring agent, can be applied to soft drinks, western-style wine, cold drinks, fruit juice concentrate, canned fruit, pickles and ice cream. As an acidic substance used as solid beverage gas production agent, it has excellent bubble durability with delicate product organization.
[Chemical properties]

Fumaric acid is naturally presented in Corydalis, mushrooms and fresh beef. Product precipitated from the water is monoclinic needle-like, prismatic or leaf-like white crystalline or crystalline powder. It is odorless with a special and strong sour, which is about 1.5 times that of the citric acid. It has a melting point 287 ° C, the boiling point of 290 ° C with subjecting to sublimation at temperature above 200 ° C. When being heated to 230 ° C, it will lose water and become maleic anhydride. Its co-boiling with water can produce DL-malic acid. It is soluble in ethanol, slightly soluble in water and ether, but insoluble in chloroform. The pH value of the 3% aqueous solution is 2.0 to 2.5 with a strong buffering performance, in order to maintain the pH of the aqueous solution at around 3.0. This product is non-toxic; rat-oral LD50: 8000mg/kg.
[Fumaric Acid Foods]

Fumaric acid has been used as a food acidulant since 1946. As a food additive, it is used as an acidity regulator and can be denoted by the E number E297. Chemically it is an unsaturated dicarbonic acid and is part of the citric acid cycle.
Fumaric acid is a common food additive included in many processed foods to keep them stable and to add tartness. The substance has a more sour flavor than citric acid, another common food additive. Fumaric acid occurs naturally in fumitory, bolete mushrooms, lichen and Iceland moss. As an additive, fumaric acid is produced synthetically, mainly from malic acid from apples. Fumaric acid as an additive is regulated under the Codex Alimentarius General Standard for Food Additives (GSFA), a collection of internationally recognized standards.The U.S. Food and Drug Administration considers it safe.
Dairy Products
Fumaric acid is included in many dairy-based products. These include dairy drinks such as chocolate milk, cocoa, eggnog, condensed milk and whey protein beverages. It also may be added to clotted cream, milk and cream powders and milk and cream analogues (substitutes). Fumaric acid is added to cheese products, including processed cheese and cheese substitutes. Dairy-based desserts, such as pudding, flavored yogurt, sherbet and sorbet may include fumaric acid as well. Dairy fat spreads and blended spreads can include fumaric acid, and so can preserved eggs and egg-based desserts such as custard.
Processed Foods
Some processed and packaged foods have fumaric acid added to them to help stabilize them and enhance their flavor. For example, many processed meats, such as bacon and canned meats, have added fumaric acid. Frozen seafood, smoked meats and the edible casings around sausages might also have fumaric acid added to them. Fermented, canned, dried and processed fruits and vegetables can contain the food additive as well. Rice cakes and other precooked rice foods, dried or preserved eggs, mustard, vinegar, cider, wine and other alcoholic beverages are additional examples of foods that might contain fumaric acid.
[Chemical reaction]

The molecular structure of fumaric acid contains conjugated maleic acid group with both ends of ethylene double bonds being connected with a carbonyl group. Its chemical properties are very lively. It can undergo Diels-Alder reaction; polymerization (self-polymerization and copolymerization); acylation, amidation, halogenation, hydrogenation, hydration or dehydration, alkylation, free radical reaction and nucleophilic reaction; isomerization: when being heated to 250~300 ° C, it can be converted into maleic acid; esterification reaction; acyl halogenation reaction, can only generate diacid chloride, not able to produce acyl chloride; oxidation and reduction reaction; oxidation with potassium permanganate can generate racemic tartaric acid; decomposition, decarboxylation reaction and sulfonation reaction.

[Side Effects]

Fumaric acid is related to malic acid, and, like malic acid , it is involved in the production of energy (in the form of adenosine triphosphate [ATP]) from food.
Fumaric acid Side Effects: Kidney disorders have been reported in people taking fumaric acid esters, possibly due to taking large amounts too quickly.9 , 10 Most studies have reported gastrointestinal upset and skin flushing as common side effects; some have also found decreased white blood cell counts with prolonged use.

1. It can be used as mordant
2. It can be used for the manufacturing of unsaturated polyester resin, pesticides, sour agents and amino acids
3. It can be used as sour agent, mostly used in combination with citric acid. It can be applied to raw noodles products and fruit juice drinking with the maximum usage amount of 0.6g/kg; it can also be used for carbonated drinks with the maximum usage amount of 0.3g/kg.
4. Fumaric acid is used for the production of unsaturated polyester resin. This kind of resin is characterized by excellent resistance to chemical corrosion as well as heat resistance; the copolymer of fumaric acid and vinyl acetate is a kind of excellent adhesive. Its copolymer with styrene copolymer is the raw material for the manufacture of glass fiber. The plasticizer of the fumaric acid is non-toxic and can be applied to the vinyl acetate latex contact with food. This product is the intermediate of pharmaceutical and optical bleaching agents and other fine chemicals. Neutralization of fumaric acid with sodium carbonate can generate sodium fumarate ([17013-01-3]), and then replaced with ferrous sulfate to get iron fumarate, being the drug Fersamal used for the treatment of small red blood cell anemic. The product, as a food additive-sourness agent, used in soft drinks, fruit sugar, jelly, ice cream with most of them used in combination with sourness agent, citric acid. The monosidum salt made from the reaction between fumaric acid and sodium hydroxide can also used as sour seasoning, also used as the intermediate of synthetic resin and mordant.
5. It can be used as acidity regulator of food with strong effect of anti-bacterial and anti-corrosive. It can also be used as acidizing agent, anti-thermal oxidation additives, curing accelerators, spices. When being used as the acid substance of solid beverage gas production agent, the resultant bubble is long-lasting and delicate; it can also applied to fine chemical intermediates of medicine and optics bleaching agents. It is used for the production of antidote, sodium dimercaptosuccinate and the drug Fersamal that used for the treatment of small red blood cell anemia. In addition, it is also used for the production of unsaturated polyester resin.
6. It can be used for calibration of standard alkaline solution. It can be used for separation of thorium from cerium, lanthanum, praseodymium and rubidium. It can be applied to synthetic resin. It can also be used as mordant and antioxidant.
[Production method]

There are many ways to produce fumaric acid in industry. Its main source is through the oxidation of benzene (or butylene) to generate maleic acid (or maleic anhydride) in the presence of the catalyst, followed by isomerization. Send the benzene (or 80% butene) together with excess air into a fluidized bed or fixed bed reactor for oxidation reaction to generate maleic anhydride. The recycled acid was absorbed into maleic acid. Then after going through decolorization filtering, maleic acid is subject to isomerization under the action of the thiourea catalyst. The reactant undergoes filtration, washing and drying to obtain fumaric acid.
Ammonium persulfate-ammonium bromide mixtures or metal salts, amine salts, mercaptans and 10-20% hydrochloric acid can be used as the isomerization catalyst.
Carbohydrates such as sucrose, glucose, maltose, after undergoing fermentation by Rhizopus nigrocans can also used for manufacturing of fumaric acid. With the method of sugar fermentation, 1t products need to consume 8 ton of grain, which is quite uneconomical. Domestic research has taken liquid paraffin instead of food fermentation, using the liquid wax with high C16-C18 content as carbon source, after 80-88 h of fermentation, can obtain a conversion rate of liquid wax of about 50% and extraction rate of 50% or more. Furfural way: take furfural as the raw material; go through sodium chlorate oxidation to obtain it. For details: supply 58.5 g of KClO3 powder to a 250 mL flask; add an appropriate amount of V2O5/MoO3 (0.8: 1) catalyst and 100 mL of a 0.5 mol/L hydrochloric acid solution. Under continuous stirring at 110 °C, add dropwise of 20 mL of furfural at a speed of 1 mL/min. After the completion of dropping, continue the reaction for 2h and then cool to room temperature; filter, and the filtrate is recovered. The filter cake is placed in 100mL distilled water, crushed, filtered to get the crude fumaric acid, followed by dilute hydrochloric acid recrystallization to get the finished product.
