Data,9, Process for the preparation of aqueous dispersions or solutions of polyurethane polyureas containing heat activated cross-linking agents, the dispersions or solutions obtainable by this process, and their use for the production of coatings.

Not to be confused with malic acid or maleic acid. Esher acid is often mistakenly believed to occur in beetroot at high concentration. Polyether-modified polyisocyanate mixtures having improved dispersibility in water. However, a study on the composition of sugar beet liquors revealed no malonic acid.

The carbanion formed can undergo nucleophilic substitution on the alkyl halide, to give the alkylated compound. Retrieved 5 June By using this site, you agree to the Terms of Use and Privacy Policy. The ionized form of malonic acid, as well as its esters and mqlonicoare known as malonates. Malonic acid is used as a building block chemical malonici produce numerous valuable compounds, [16] including the flavor and fragrance compounds gamma-nonalactone, cinnamic acidand the pharmaceutical compound valproate.


Malonic ester synthesis – Wikipedia

Additionally, the coenzyme A derivative of malonate, malonyl-CoAis an important precursor in fatty acid biosynthesis along with acetyl CoA. For example, diethyl malonate is malonic acid’s diethyl ester.

Malonyl CoA is formed from acetyl CoA by the action of acetyl-CoA carboxylaseand the malonate is transferred to an acyl carrier protein to be added to a fatty acid chain.

Mit Soft-Touch-Lack beschichtete, verformbare Kunststoffverbundfolien und Kunststoffverbundelemente sowie deren Herstellung.

Malonic acid up to Crosslinked native and waxy starch resin compositions and processes for their manufacture. This work has been released into the public domain by its author, Manderson Views View Edit History.

Malonic acid

The carbons alpha to carbonyl groups can be deprotonated by a strong base. Process for the production of polyisocyanates containing isocyanurate groups and their use. Malonic acid was listed as one of the top 30 chemicals to be produced from biomass by the US Department of Energy.

Carbon-carbon bond forming reactions Substitution reactions. It can also be a component in alkyd resinswhich are used in a number of coatings applications for protecting against damage caused by UV light, oxidation, and corrosion.

Malonic acid is the classic example of a competitive inhibitor: Retrieved from ” https: In citrus, fruits produced in organic farming contain higher levels of malonic acid than fruits produced in conventional agriculture. This page was last edited on 27 Octoberat Sodium carbonate generates the sodium saltwhich is then reacted with sodium cyanide to provide the cyano acetic acid salt via a nucleophilic substitution.

Other names Malonic acid Methanedicarboxylic acid. It is used in a number of manufacturing processes as a high value specialty chemical including the electronics industry, flavors and fragrances industry, specialty solvents, polymer crosslinking, and pharmaceutical industry.
