The present invention relates to a method for the separation of acetic acid and water, mainly to solve the prior art high power consumption and high acetic acid dehydration process equipment manufacturing costs. 本发明通过采用对醋酸脱水塔加压的方式进行精馏脱水,热泵循环中采用水作为换热介质,醋酸脱水塔...
The present invention relates to a method for recycling water from a separation system for acetic acid and water. Materials with high water content are added to an azeotropic rectifying column; all light component oil flows back to the azeotropic rectifying column; water phase penetrates into a ...
Both these experimental data and our earlier results for acetic acid-water mixtures with supercritical carbon dioxide have been used to test an equation of state which has recently been developed by Grenzheuser and Gmehling for systems which contain associating fluids. Results indicate that the ...
1. Acetic acid is widely distributed in nature. For example in fruit or vegetable oils, mainly in the form of esters; in the tissues of animals, excretions and blood are present in the form of free acids. Many microorganisms can convert different organisms into acetic acid by fermentation...

Liquidliquid equilibria for the acetic acid + water + amyl acetate and acetic acid + water + 2-methyl ethyl acetate ternary systems were measured at (304.15, 332.15, and 366.15) K under atmospheric pressure. The experimental data were correlated with the NRTL model, and its interaction parameter...
Acetone is a volatile, colorless solvent used in industry and nail polish remover, whereas Acetic Acid is a sour-tasting liquid that acts as vinegar's main component and an industrial chemical.
Different viscosity grade sodium alginate (NaAlg) membranes and modified sodium alginate membranes prepared by solution casting method and crosslinked with glutaraldehyde in methanol:water (75:25) mixture were used in pervaporation (PV) separation of water+acetic acid (HAc) and water+isopropanol mixtur...
Vinegar is a naturally-occurring liquid that contains many chemicals, so you can't just write a simpleformulafor it. It is approximately 5-20% acetic acid in water. So, there are actually two main chemical formulas involved. Themolecular formulafor water is H2O. The structural formula for ac...
