Abstract
Silicalite with increased hydrophobicity may be made by steaming silicalite in an atmosphere of at least 10% water vapor at temperatures of 650.degree.-850.degree. C. When used as monodisperse spheres with a diameter in the range 1-20 microns such ultrahydrophobic silicalite is an excellent adsorbent for chromatographic separation of polar materials, including fatty acids, at both the analytical level and preparative level using simulated moving bed techniques.
