Acetic acidSilicaliteComposite membraneAbsorbentThe preferential pervaporation of acetic acid over water is achieved with silicalite filled polydimethylsiloxane (PDMS) membranes. The effect of silicalite addition is not positive at the feed temperature of 25掳C, but improves with increasing feed temperature...

Acetic acid, the most important of the carboxylic acids. Industrially, it is used in the preparation of metal acetates, used in printing processes; vinyl acetate, used in the production of plastics; cellulose acetate, used in making photographic films an
Acid anhydrides contain two acyl groups and have the general formula RC(=O)OC(=O)R or acyl—O—acyl. The acyl groups may be the same (symmetric) or different (asymmetric or mixed). The simplest and most common acid anhydrides are symmetrical derivatives of monobasic acids. Whether substitute...
The resulting mixed acid was separated by 6 columns of acetic acid. Refining method: acetic acid contains water, acetaldehyde, acetone, formic acid, propionic acid, esters, sulfates, sulfites, chloride, acetate and other impurities. The purification is carried out by adding equimolar anhydride to ...
Preferably the solvent is acetic acid mixed with water, in a ratio of about 5:1 to about 25:1, preferably between about 8:1 and about 20:1. Throughout the specification, acetic acid will be referred to as the solvent. However, it should be appreciated that other suitable solvents, such...
