    Solvolysis of esters

    Water generated by esterification can be removed as it is formed by way of pervaporation. We obtained some pretty good results with a ceramic pervaporation membrane, even under acidic environment. You can contact me at: maurice.velterop@pervatech.nl

    extractive distillation

    Maybe it is somewhat out of the scope of this discussion, but DMF and water can be readily separated by pervaporation.Take a look at www.pervatech.com

    Molecular Sieve Dehydration of Ethanol

    For pervaporation membranes that can handle temperatures up to 250 degrees C, I refer to the web page: www.pervatech.nl. They have ceramic pervaporation membranes suitable for pervaporation or vapor permeation. Dehydration of ethanol at these temperatures is not a problem for these type of...
