A new procedure for the synthesis of barbituric acid was written by Dick, J.;Drugarin, C.. And the article was included in Acad. Rep. Populare Romine, Baza Cercetari Stiint. Timisoara, Studii. Cercetari Stiinte Chim. in 1961.Related Products of 1190-39-2 This article mentions the following:
A mixture of 120 g. butanol, 50 g. malonic acid, and 3.7 g. H2SO4 is refluxed two hours to yield 72.5% pure dibutyl malonate (I), n20D 1.4255, d20 1.0005. I (15 g.) and 6 g. urea in 50 g. butanol is added to 50 g. butanol containing 2 g. Na; the mixture is refluxed two hrs., cooled to 70° 80 g. H2O and 10 g. HCl added, and the mixture further cooled to 40° and filtered to yield 73% barbituric acid (II). In the experiment, the researchers used many compounds, for example, malonic acid dibutyl ester (cas: 1190-39-2Related Products of 1190-39-2).
malonic acid dibutyl ester (cas: 1190-39-2) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Esterification is the general name for a chemical reaction in which two reactants (typically an alcohol and an acid) form an ester as the reaction product. Esters are common in organic chemistry and biological materials.Related Products of 1190-39-2
