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. Cyclic esters are called lactones, regardless of whether they are derived from an organic or inorganic acid. One example of an organic lactone is γ-valerolactone.Related Products of 1190-39-2

Preparation of malonic acid and its esters from carbon suboxide was written by Dashkevich, L. B.. And the article was included in Doklady Akademii Nauk SSSR in 1960.Related Products of 1190-39-2 This article mentions the following:

Pyrolysis of Ac2O solution of di-Et oxaloacetate best at 850-75° gave 45% C3O2. This passed into H2O containing a trace of HCl gave 97% malonic acid. Similar reaction with ROH in the presence of a few drops of HCl gave the following malonates: di-Me, 96%; di-Et, 97%; di-Pr, 94%; di-Bu, 90%; dicyclohexyl, 61%; dibenzyl, 38%; diphenyl, 69%. The reaction was best run at 60-70°. In the experiment, the researchers used many compounds, for example, malonic acid dibutyl ester (cas: 1190-39-2Related Products of 1190-39-2).
