LiquidLiquid Equilibria of Selected Dibasic Ester + Water
Experimental liquidliquid equilibria for various dibasic ester + solvent + water systems were obtained at 297 K. These systems are suggested as possible substitutes in applications where chlorocarbons and aromatic hydrocarbons are used. The dibasic esters can also be used as novel solvents in separation techniques.
CN101525446B - Method for refining dibasic acid dimethyl
The invention discloses a method for refining a dibasic acid dimethyl ester plasticizer, which comprises the following steps: dibasic acid dimethyl ester plasticizer crude product is refined by adopting a continuous decompression and rectification light-component and heavy-component removing method, after being filtered, the plasticizer crude product firstly enters a lightness-removing column
Synthesis of novel plasticizer ester end-capped oligomeric
In this work, a novel high efficiency plasticizer, an ester-capped oligomeric lactic acid mixture (EOL), was successfully synthesized by a two-step esterification reaction, with L -lactic acid as the main raw material. The structure of EOL was characterized by using FT-IR, 1 H NMR and time of flight mass spectrometry (TOF-MS).
FlexaTrac-DME | Ascend Performance Materials
FlexaTrac-DME (dimethyl or dibasic esters) is a clear, colorless, low-odor liquid produced by reacting methanol with streams of adipic, glutaric and succinic acids and then separated via fractionation. FlexaTrac-DMEs provide attractive alternatives to other solvents: Low volatile organic compounds (VOC) Biodegradable High solvency power
Dibasic ester
Dibasic ester or DBE is an ester of a dicarboxylic acid. Depending on the application, the alcohol may be methanol or higher molecular weight monoalcohols. Mixtures of different methyl dibasic esters are commercially produced from short-chain acids such as adipic acid, glutaric acid, and succinic acid. [1]
- What is dibasic esters?
- Dibasic esters.DBE blend is a clear, colorless liquid, with mild odor. It is an excellent alternative to other traditional solvents because of some of its properties such as; Low (negligible) toxicity, Low vapor pressure (high boiling point), slow evaporation, high flash point, high miscibility
