bubble points measurement for triethyl orthoformate Diethyl Malonate
The Journal of Chemical Thermodynamics, 2004Co-Authors: Congmin Wang, Yong Wang, Shijun HanAbstract:Abstract The bubble points for (triethyl orthoformate + Diethyl Malonate) at T = (373.15, 383.15, and 393.15) K and at p = 13.33 kPa, measured with an inclined ebulliometer are presented. The experimental results are analyzed using the UNIQUAC equation with the temperature-dependent binary parameters with satisfactory results. Experimental vapour pressures of triethyl orthoformate are also included.

110th Anniversary: Effects of Alcohol Concentration on the Reactions of Ethyl Acetate and Diethyl Malonate in Hot Compressed Water–Alcohol Mixed Solvents
Industrial & Engineering Chemistry Research, 2019Co-Authors: Makoto Akizuki, Kohki Ito, Yoshito OshimaAbstract:The effects of the alcohol concentration of a hot compressed water–alcohol (methanol or ethanol) mixture on acid-catalyzed ester reactions were investigated. In the water and water–methanol mixture, ethyl acetate reactions were promoted by the autocatalytic effect of the produced acetic acid, while Diethyl Malonate reactions were promoted by the catalytic effect of the solvent molecules. The kinetic analyses indicated that the catalytic effect of H+ derived from the dissociation of acetic acid decreased as methanol concentration increased. The catalytic effect of water molecules was highest in a mixed solvent of 10 mol % methanol, and that of methanol molecules increased as methanol concentration increased. In the water–ethanol mixture, the hydroxyl-decarboxylation of Diethyl Malonate to ethyl acetate and hydrolysis of ethyl acetate to acetic acid proceeded consecutively. The secondary ethyl acetate hydrolysis was suppressed in the water–ethanol mixture because of the differences in the effects of alcohol...
