Exempel på hur man kan använda MALONIC i en mening

• In 1951, while trying to find the non-organic analog to the Krebs cycle, he noted that in a mix of potassium bromate, cerium(IV) sulfate, malonic acid, and citric acid in dilute sulfuric acid, the ratio of concentration of the cerium(IV) and cerium(III) ions oscillated, causing the colour of the solution to oscillate between a yellow solution and a colorless solution.
• The nitrile group can be hydrolyzed with sodium hydroxide to sodium malonate, and acidification affords malonic acid.
• The Doebner modification of the Knoevenagel condensation entails the use of pyridine as a solvent with at least one of the withdrawing groups on the nucleophile is a carboxylic acid, for example, with malonic acid.
• As an alternative to its original preparation, Meldrum's acid can be synthesized from malonic acid, isopropenyl acetate (an enol derivative of acetone), and catalytic sulfuric acid.
• Ethyl acetoacetate is often used in the acetoacetic ester synthesis, comparable to diethyl malonate in the malonic ester synthesis or the Knoevenagel condensation.
• A number of other methods exist, including the Knoevenagel condensation of acetaldehyde with malonic acid in pyridine:.
• Methohexital can be synthesized in the classic manner of making barbituric acid derivatives, in particular by the reaction of malonic ester derivatives with derivatives of urea.
• The residual mixture contains iodinated malonic acid, inorganic acid, manganous catalysts, unreacted iodate and hydrogen peroxide.
• The malonic ester synthesis is a chemical reaction where diethyl malonate or another ester of malonic acid is alkylated at the carbon alpha (directly adjacent) to both carbonyl groups, and then converted to a substituted acetic acid.
• If elevated methylmalonic acid levels are accompanied by elevated malonic acid levels, this may indicate the metabolic disease combined malonic and methylmalonic aciduria (CMAMMA).
• In the metabolic disease combined malonic and methylmalonic aciduria (CMAMMA), acyl-CoA synthetase family member 3 (ACSF3) is reduced, which converts toxic methylmalonic acid to methylmalonyl-CoA and thus supplies it to the citric acid cycle.
• For the first step, the dianion from malonic acid half-ester is formed by treatment with butyllithium.
• Boris Belousov first noted, sometime in the 1950s, that in a mix of potassium bromate, cerium(IV) sulfate, propanedioic acid (another name for malonic acid) and citric acid in dilute sulfuric acid, the ratio of concentration of the cerium(IV) and cerium(III) ions oscillated, causing the colour of the solution to oscillate between a yellow solution and a colorless solution.
• Mutations in this gene have been shown to cause combined malonic and methylmalonic aciduria (CMAMMA).
• The compound is then condensed with ethoxy methylene malonic diethyl ester (EMME) and cyclized thermally (2).
• Early methods to produce BABA included from ammonia and crotonic acid under pressure; from the acetoacetic ester phenylhydrazone; or from malonic acid, acetaldehyde, and ammonia.
• Sodium or potassium ethoxide is also a suitable base for the malonic ester synthesis where diethyl malonate is used, since any transesterification reaction does not result in ester scrambling.
• It reduced malonic dialdehyde formation and increased integral antiradical activity in toxic liver damage in vivo.
• Unlike other malonic esters that are derived via malonic ester synthesis, diethyl phenylmalonate is typically indirectly derived via a Claisen condensation with diethyl oxalate and ethyl phenylacetate followed by decarbonylation.
• A copper based catalyst system has been developed for efficient aldol generation at mild conditions (Figure "Decarboxylative aldol reaction with malonic acid half thioester").
