WebReagents & Solvents: Molecular Sieves. Definition: Molecular sieves are a microporous material which can selectively adsorb gases and liquids. They are synthetic zeolites (crystalline metal aluminosilicates) which upon dehydration can efficiently and selectively remove water or other solvents. The selectivity of a molecular sieve is determined ... WebPhysically active agents adsorb water on the surface and in the pores of the matrices and can be regenerated by heating or applying a vacuum. Examples include: t.h.e.® Desiccant, silica gel, molecular sieve, aluminum oxide, etc. Chemically active agents have two possible modes of action.
