Nota de aplicación
Any crystalline substance belonging to the class of zeolites as used for separation and filtering. Molecular sieves are honeycombed with regularly spaced cavities of uniform and very small size that block larger, foreign molecules and let smaller ones pass. A typical use is as response to vinegar syndrome in film. The molecular sieve has been employed as a scavenger for the acetic acid emitted during acetate-based negative degradation.
