ABSTRACT:
This invention relates to the use of pore mouth control of microporous solids for developing novel molecular sieve adsorbents and their potential in the drying of alcohols. More specifically, the invention relates to the manufacture and use of a molecular sieve adsorbent, which selectively adsorbs water from azeotropic alcohol-water mixtures by pore mouth control of microporous solids with liquid phase metal alkoxide deposition on the external surface at ambient conditions of temperature and pressure. The prepared adsorbent is therefore useful for the commercial drying of alcohols.
