Reactions with carbon suboxide was written by Hagelloch, Gunter;Feess, Erich. And the article was included in Chemische Berichte in 1951.HPLC of Formula: 1190-39-2 This article mentions the following:
C3O2 undergoes reactions at elevated temperatures without any noteworthy polymerization. When it is passed into dry PhMe at 100° the solution becomes increasingly yellow with a green fluorescence and, on evaporation, 20% of the C3O2 is recovered as polymers. In nonpolar solvents in the presence of AlCl3, or p-MeC6H4SO2H (I) at 20° no reaction takes place. Methylene bases of the Fischer-base type behave like tertiary bases and accelerate polymerization. With alcs. at 30° a slow reaction takes place; it is considerably accelerated at 65-70° with the formation of CH2(CO2R)2 (II). C3O2 is prepared in 40-43% yield by thermal decomposition of diacetyl tartaric anhydride at 770° (cf. C.A. 27, 1325). The reactions are carried out by passing the gas through a fritted distributor into the alc., either without a solvent or in PhMe, xylene, PhNO2, (CH2Cl)2 (III), or CH2(CO2Et)2 at 80°. The following II are prepared: R-CH2:CHCH2, b13 119-20°; CH2ClCH2, prepared in PhMe in 13.5% yield, b13 174°; cyclohexyl, 25% at 25°, 56% at 80° or at 25° with ultraviolet irradiation, or 70% at 80° in the presence of I, b13 194°; Me3C, in PhMe at 70°, b13 105°; p-MeC6H4, in PhMe with irradiation, small leaflets, m. 70°; p-O2NC6H4, in PhNO2 at 110°, leaflets, m. 174° (decomposition); picryl, in PhNO2 at 80°, leaflets, m. 102°; o-HO2CC6H4 (IV), in III with irradiation, long thin needles, m. 144° (decomposition); 3,5,2-Br2(HO2C)C6H2 (V), in xylene, fine needles, m. 176° (decomposition); 2-HOC6H4, in boiling C6H6, m. 140°, soluble in dilute NaOH, giving a red-violet color with FeCl3. CH2(COSBu)2, b13 178°, and CH2(COSCH2Ph)2, b2 195°, are prepared from the corresponding mercaptans in PhMe at 70°. C3O2 and glycol at 80° give a poly glycol malonate as a dark viscous oil; C3O2 and (CH2CH2OH)2 give a very viscous dark poly butanediol malonate. The reactivity of C3O2 is as follows: amines > primary alcs. > phenols and nitrophenols > secondary alcs. and H2O > thiols > tertiary alcs. IV stops the growth of Mycobacterium tuberculosis var. hominis in a solution of 1:40,000 on the Kirchner-Hermann, and 1:10,000 on the Hohn nutrient medium; V shows a lesser action. In the experiment, the researchers used many compounds, for example, malonic acid dibutyl ester (cas: 1190-39-2HPLC of Formula: 1190-39-2).
malonic acid dibutyl ester (cas: 1190-39-2) belongs to esters. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. Liquid esters of low volatility serve as softening agents for resins and plastics. Esters also include many industrially important polymers. Polymethyl methacrylate is a glass substitute sold under the names Lucite and Plexiglas; polyethylene terephthalate is used as a film (Mylar) and as textile fibres sold as Terylene, Fortrel, and Dacron.HPLC of Formula: 1190-39-2
