Abstract
The present invention relates to the modification of the internal surfaces of zeolite crystals via treatment with alcohols containing at least four carbon atoms. The modified zeolites possess high thermal stability and the properties of the modified zeolites can be tailored to provide improved performance for use in separations processes.
