Technical solution is: A DMAC azeotrope separation of acetic acid in the process, according to the following steps: 1) the use of weak base resin adsorption of acetic acid; adding water absorbent resin elution DMAC DMAC azeotrope materials in aqueous diluted to 5 ~ 90% of the material, and...
Examples include: water, alcohols (methanol, ethanol, or isopropanol), formaldehyde, acetic acid, acetone, and methyl ethyl ketone. Hydrophobic Solvents. Hydrophobic solvents can be either polar or nonpolar compounds and have an affinity for oils and greases, which they readily dissolve. They are ...
Study of the entrainer of n-Butyl acetate in azeotropic distillation simulation for acetic Acid-water system HAC-H_2O共沸精馏过程中共沸剂醋酸正丁酯的模拟研究 2. In order to separate n-hexane-ethyl acetate azeotrope,batch azeotropic distillation was often used and the entrainer played a key ro...

This article reports on a particularly effective binary repellent blend of ethyl butylacetylaminopropionate and nonanoic acid. A composition containing 25 mol% of the acid exhibits negative pseudo-azeotrope behaviour at 50 °C, meaning that the liquid vapour pressure is lower than that of the ...
A process for the separation of water from a water-containing mixture of azeotrope, with an extractant which removes water from the mixture or azeotrope, recovery of the non aqueous portion of the mixture or azeotrope as a product, and regeneration of the extractant for reuse by the removal ...
Isobaric Vapour-Liquid Equilibrium Data Measurement for a Binary System of Green Solvent 2-Methyltetrahydrofuran and Acetic acid at 101.3 kPa The VLE data were generated through binary interaction parameters from Aspen Hysys for Wilson, NRTL and UNIQUAC models and compared with the experimental ... ...
PURPOSE:To separate acetic acid and water in high efficency by azeotropic distillation of a mixture of acetic acid and water in the presence of an entrainer, detecting and controlling the change of the concentration of the components or the temperature in the azeotropic distillation zone.YOSHIDA, ...
Reports the discovery of a boiling state of constant composition and temperature in a mixture of acetic acid, isopropanol, isopropyl acetate and water that is simultaneously in both reaction and phase equilibrium. The knowledge of the existence of azeotropes in multicomponent mixtures in the absence ...
Here we report the discovery of a boiling state of constant composition and temperature in a mixture of acetic acid, isopropanol, isopropyl acetate and water that is simultaneously in both reaction and phase equilibrium. These states, which we call reactive azeotropes, were predicted recently. ...
