Its crystalline structure has been analyzed. Malic acid is a substance found naturally in apples and pears. Maleic acid is very less soluble than fumaric acid in water. 110-16-7 - VZCYOOQTPOCHFL-UPHRSURJSA-N - Maleic acid [NF] - Similar structures search, synonyms, formulas, resource links, and other chemical information. Maleic acid, also called cis-butenedioic acid (HO 2 CCH=CHCO 2 H), unsaturated organic dibasic acid, used in making polyesters for fibre-reinforced laminated moldings and paint vehicles, and in the manufacture of fumaric acid and many other chemical products.Maleic acid and its anhydride are prepared industrially by the catalytic oxidation of benzene. Malic Acid is an organic compound, a dicarboxylic acid that is the active ingredient in many sour and tart foods. major precursor for the compound fumaric acid. 100g; Plastic bottle. It is sometimes used as medicine. Maleic acid has a melting point of 275°F. fumaric acid will be obtained. ⦠The presence of a double bond Hence by performing hydration of maleic anhydride, maleic acid can be easily obtained, maleic anhydrides can be commercially produced by reacting butane with oxygen with vanadium as a catalyst. It is very dangerous for the skin and is also very toxic. Hydrogen methyl maleate. Component log Pow Maleic acid 0.32 13. helps in converting fumaric acid into sulfosuccinic acid and malathion. Molecular Weight 160.04 (anhydrous basis) MDL number MFCD00150133. Fumaric acid, methyl ester. Methyl hydrogen maleate. isomers. By performing catalytic oxidation on a benzene compound maleic acid and maleic anhydride can be obtained. This type of acid is perfect for adding in salts with drugs so that they can become more stable, for example, indacaterol maleate. Disposal considerations By using the process of catalytic isomerization fumaric acid can be obtained from maleic acid. It can convert glycols into polyesters by esterification and to anhydride by dehydration. Also sold in dietary supplement form, malic acid is said to offer a variety of benefits. Structure, properties, spectra, suppliers and links for: Maleic anhydride, 108-31-6. The structure of maleic acid consists of four carbon molecules along with carboxylate groups on either ends, with a double bond between the central carbon atoms. that is a white crystalline powder. Maleic anhydride rapidly hydrolyzes to form maleic acid in the presence of water and hence environmental exposures to maleic anhydride itself are unlikely. The salts and esters of malic acid are known as malates. FIRST AID MEASURES General advice Consult a physician. 3052-50-4. Maleic acid Revision Date 25-May-2018 (Pimephales promelas) (Daphnia magna) Persistence and DegradabilityPersistence is unlikely Bioaccumulation/ AccumulationNo information available. Maleic acid is also known as cis-butenedioic acid which has a chemical formula of HO2CCH=CHCO2H and is an unsaturated compound. Malic Acid. If not breathing, give artificial respiration. hydrogen bonding is very crucial. The malate anion is an intermediate in the citric acid cycle. Structure, properties, spectra, suppliers and links for: (±)-Malic Acid, 617-48-1, 6915-15-7. It is an organic compound and is a dibasic acid which is used in manufacturing fumaric acid, polyesters for fiber lamination, moldings and paints for vehicles, and many other chemical products. Malic acid (E296 or INS 296, Fig. Shop a large selection of Maleic Acid products and learn more about Maleic Acid, 99%, ACROS Organics. This problem has been solved! But still, these two acids have very different physical properties. This is another method for obtaining fumaric acid. 3 Effective date : 12.14.2014 Page 2 of 8 Maleic Acid Created by Global Safety Management, 1-813-435-5161 - www.GSMSDS.com This maleic acid is also called as maleic acid or toxilic acid.
