https://doi.org/10.1007/978-3-540-71325-8he presence on the zeolite of active sites other than acid sites or with the presence of impurities in the reactional mixture or again with the rapid formation of a coke deposit. The conditions for a precise characterization of the zeolite porous structure will be specified.

Zeolite-Induced Selectivity in the Conversion of the Lower Aliphatic Carboxylic Acids,yric acid as feed. Propionic acid is an intermediate case. With butyric acid a highly selective ketonization reaction into 4-heptanon occurs on zeolites containing an erionite cage in their structure.

Intracrystalline Complexation by Crown Ethers and Cryptands in Clay Minerals,lacing water molecules which belong to the hydratation sphere of the exchangeable cations. Stoichiometry, geometry, packing arrangement, acidic-base reactions, etc., are determined by the nature of the interlayer cations, as well as the mineral charge and steric limitations imposed by the host lattice.
