Carbon suboxide and some of its reactions. XX. Reaction of carbon suboxide with sodium alcoholates was written by Dashkevich, L. B.;Pechenyuk, V. A.. And the article was included in Zhurnal Obshchei Khimii in 1965.Recommanded Product: malonic acid dibutyl ester This article mentions the following:
Passage of C3O2 into RONa in ROH gave colorless precipitates, which heated with EtI 4-6 hrs. gave CH2(CO2R)2 and EtCH(CO2R)2, resp. (R shown): Me, 91%, b762 179-81°, and 0%; Et, 95%, b752 197-8°, and 0%; Pr, 80%, b762 229-30°, d2020 0.9798, n20D 1.4204, and 13.9%, b762 240-1°, 0.9863, 1.4219; Bu, 56%, b5 118-20°, 0.9650, 1.4265, and 37.3%, b5 130-2°, 0.9531, 1.4281; n-C6H13, 41.6%, b6 143-5°, 0.9211, 1.4370, and 53%, b6 168-70°, 0.9053, 1.4310; n-C7H15, 38.8%, b7 173-5°, 0.9228, 1.4365, and 61%, b7 190-2°, 0.9159, 1.4388; cyclohexyl, 38.2%, b10 168-70°, 1.0154, 1.4725, and 46%, b10 190-1°, 1.0289, 1.4742; n-C8H17, 0%, and 84.5%, b7 209-11°, –, 1.4430. In the experiment, the researchers used many compounds, for example, malonic acid dibutyl ester (cas: 1190-39-2Recommanded Product: malonic acid dibutyl ester).
malonic acid dibutyl ester (cas: 1190-39-2) belongs to esters. Esters are also usually derived from carboxylic acids. It may also be obtained by reaction of acid anhydride or acid halides with alcohols or by the reaction of salts of carboxylic acids with alkyl halides. 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.Recommanded Product: malonic acid dibutyl ester
