Abstract
BY using crystalline network lattices with uniform interstices as sorbents, it has proved possible to carry out a great many resolutions of molecular mixtures1. Molecules which are of the right dimensions to enter and occupy the intra-crystalline interstices are then removed by selective sorption, leaving behind molecules which are too large or have the wrong shape, and hence toward which the network lattice is a non-sorbent. Crystalline parameters define with precision the dimensions of the interstices (which are linked to give channels) ; and, therefore, the molecular sieve action is equally clearly defined. As a result separations become quantitative in numerous instances (for example, n-paraffins from iso-paraffins using dehydrated chabazite as sorbent).
