It has been proven for the first time that the incorporation of methyl groups in microporous silica membranes enhances the service time in the dehydration of a butanol/water mixture at 95°C from a few weeks to more than 18 months. The observed water flux fluctuates between 4 and 5 kg/h·m2, and decreases with only ~7% per year, and the selectivity ranges between 500 and 20,000.
